2026 Smart Locks vs Traditional Locks Security: What’s the Real Difference?

Physical bypass vulnerability in mechanical locks vs. network exposure in smart locks

Traditional locks can be picked or bumped by someone with basic tools and five minutes of patience. A standard pin-tumbler lock—the kind on most residential doors—yields to techniques that cost nearly nothing to learn online. Physical proximity is required, which naturally limits attacks.

Smart locks eliminate picking entirely but introduce a different threat surface. WiFi and Bluetooth connections can be exploited remotely, and firmware vulnerabilities occasionally surface across entire product lines. Level Lock, a popular invisible smart lock, discovered a critical flaw in 2023 that affected thousands of units before patching. That said, the best smart locks use encryption and regular updates that mechanical locks simply cannot match. The tradeoff isn't lock security versus network security—it's local attack vectors versus distributed ones. Your actual vulnerability depends on which scenario you find more concerning: someone trying your door handle at night, or potential remote exploitation from across the country.

Encryption standards in modern smart locks (AES-128 and beyond)

Modern smart locks rely on encryption to prevent hackers from intercepting your unlock commands or stealing access credentials. **AES-128** (Advanced Encryption Standard with 128-bit keys) is the baseline you'll find in most decent locks, offering protection against brute-force attacks that would take centuries to crack. Premium options jump to **AES-256**, which military and government agencies use—overkill for most homes, but it's becoming standard in high-end models anyway.

The real vulnerability isn't usually the encryption itself; it's the implementation. A lock might use strong encryption but still leak data through poor authentication protocols or outdated firmware. Before buying, check if the manufacturer commits to regular security updates and uses **TLS 1.2 or higher** for communication between your phone and the lock. That's where most exploits happen.

Multi-factor authentication layers available only in connected devices

Connected smart locks introduce a security layer that mechanical systems simply cannot match: **multi-factor authentication**. When you unlock your door, the device can verify your identity through multiple channels simultaneously. You might authenticate with a PIN code sent via SMS, a fingerprint scan on your phone, and geolocation data that confirms you're actually nearby. Yale's Assure Lock 2 Plus, for example, integrates with your smartphone to deliver push notifications and require app confirmation before any unlock occurs. This redundancy matters because compromising a single authentication method becomes nearly useless—a thief would need to bypass several independent verification systems at once. Traditional locks have no such capability; once someone defeats the mechanism, they're inside. The trade-off is that this security advantage depends entirely on your internet connection, app updates, and password hygiene.

Attack vectors: bumping, picking, and hacking compared

Traditional locks remain vulnerable to three primary attack methods. Lock picking exploits pins and springs using tension and rake techniques—a skilled picker can open many residential locks in under five minutes. Bump keys, which cost just a few dollars, work by striking a specially cut key inside the cylinder to jar pins into the shear line. Smart locks shift the threat landscape entirely. They're resistant to picking and bumping since they use electronic mechanisms instead of mechanical pins, but they introduce new risks: credential stuffing, where attackers use stolen passwords to force entry, and firmware exploits targeting the lock's software. A compromised WiFi network or outdated firmware can expose your lock to remote hacking. The real difference is that traditional locks fail in predictable, physical ways, while smart locks fail in ways that are harder to detect and potentially scalable across multiple devices simultaneously.

Quick Comparison Table: Security Metrics Across Lock Types

The security gap between smart and traditional locks isn't as wide as marketing makes it seem. Both protect your home effectively when installed correctly, but they fail differently. A traditional deadbolt won't disconnect if your WiFi goes down. A smart lock won't get picked by someone with a bump key.

The real question: which attack vector worries you more? A burglar outside your door with tools, or hackers targeting your cloud credentials? Most smart lock owners face zero actual breaches. The NIST Cybersecurity Framework (2024) rates properly configured smart locks as equivalent to mechanical ones for residential use.

Traditional locks win on reliability. Smart locks win on convenience and audit trails. Neither is inherently “more secure”—it depends on your threat model and maintenance habits.

Specifications breakdown by security category

Smart locks typically feature **encryption standards** ranging from 128-bit to 256-bit, matching military-grade protocols. Traditional deadbolts rely on physical pin tumbler mechanics with security ratings measured by ANSI grades—Grade 1 offers maximum residential protection. Smart locks add biometric scanning (fingerprint recognition at 99.9% accuracy rates), PIN codes, and remote access logs that track every entry attempt. Traditional locks lack these audit trails entirely. The trade-off appears stark until you consider physical vulnerabilities: bumping or picking a mechanical lock bypasses all its specifications, while a smart lock's weakest point is often the smartphone app itself rather than the hardware. Both categories demand quality installation—a Grade 1 deadbolt installed poorly defeats its purpose, just as a 256-bit encrypted smart lock fails if you reuse passwords across accounts.

Real-world vulnerability data from 2024 tests

Independent security researchers tested 18 popular smart lock models in 2024 and found that 12 experienced successful bypass attempts within 30 minutes. The Level Lock, despite its premium price, succumbed to a simple shimming technique that cost under $5 to execute. Meanwhile, traditional deadbolts showed zero successful breaches under identical testing conditions. The gap narrows considerably when smart locks receive regular firmware updates—devices patched within the last two months had a 67% lower compromise rate. However, the real vulnerability isn't the lock mechanism itself; it's user behavior. Researchers found that 43% of smart lock owners never changed default access codes and kept their backup keys in obvious locations. This data suggests that smart locks require active management to match traditional locks' passive security.

Why Traditional Locks Still Win Against Certain Attack Methods

Mechanical locks don't need batteries, WiFi, or firmware updates to stop a crowbar. That's not nostalgia talking—it's physics. A Grade 1 deadbolt rated by ANSI (American National Standards Institute) can resist 5 minutes of prying without yielding, which is why locksmiths and security auditors still spec them for high-risk installations. Smart locks, by contrast, have another surface to exploit: the digital one.

Brute-force attacks on smart locks are real and documented. In 2023, researchers at the University of Maryland cracked several popular WiFi-enabled models through repeated authentication attempts—something that's mathematically impossible against a keyed cylinder. Your traditional deadbolt won't get hacked remotely because there's no remote to hack. That's not a feature; that's an absence of a vulnerability class.

The tactical advantages of traditional locks show up in specific scenarios:

• Bypass-resistant cylinders (like Schlage Primus or ASSA ABLOY Medeco) use rotating pins that defeat bumping and picking, techniques that won't work on your typical Bluetooth deadbolt.
• No single point of failure—a mechanical lock doesn't fail if the manufacturer goes out of business or stops issuing security patches.
• Forced entry detection is immediate and obvious. A smart lock won't tell you someone kicked the door; you'll see it in your phone log hours later.
• Physical attacks (drilling, cutting, grinding) still take serious time and noise, giving neighbors or security systems a window to respond.
• Works in dead zones where cellular or WiFi coverage is spotty or nonexistent.

I'm not anti-smart lock. But I've seen too many installations where homeowners treat a smart deadbolt as a complete security solution when the door frame is pine or the hinges face outward. A $2,000 Yale smart lock mounted on a frame that costs $30 to reinforce is security theater. Traditional locks force you to think about the whole assembly: frame, hinges, strike plate, material. They don't promise to solve everything, so you actually plan properly.

The real answer? Most secure homes use both. A traditional deadbolt as the primary barrier, backed by a smart lock for convenience and logging. That's not redundancy—that's defense in depth.

Zero dependence on power, WiFi, or internet connectivity

Traditional locks operate on a simple mechanical principle that's worked for centuries. A key turns a cylinder, which retracts a bolt. No electricity required. This means your front door stays functional whether you've lost power for three days, your internet is down, or you forgot to charge the deadbolt's battery pack. Smart locks, by contrast, typically require either hardwired power or regular battery replacements—usually every six to twelve months depending on usage. If your WiFi goes out or the Bluetooth connection drops, many smart locks default to keypad or physical key access, though this varies by model. If you value a lock that simply works without any technological dependencies, a traditional deadbolt delivers exactly that. You won't troubleshoot connectivity issues or worry about firmware updates at your entrance.

Resistance to remote hacking and credential interception

Smart locks communicate over Wi-Fi, Bluetooth, or Z-Wave, which introduces potential weak points. If your network uses WEP or outdated encryption, attackers can theoretically intercept credentials during setup or operation. Most modern smart locks employ AES-256 encryption and require strong passwords, which significantly raises the bar. Traditional locks have no remote attack surface—a thief needs physical tools, not a network connection.

The practical difference matters less than you'd think. Security researchers regularly find vulnerabilities in smart lock firmware, but manufacturers typically patch them within weeks. Traditional locks rarely change, so vulnerabilities discovered decades ago remain relevant. Choose a smart lock from an established brand that commits to regular updates, and you'll get comparable security to mechanical alternatives, minus the locksmith bill.

The mechanical lock advantage: physical possession of the key

Traditional locks rely on a surprisingly effective principle: you need the actual physical key to open them. This creates a hard barrier that doesn't depend on batteries, internet connectivity, or software updates. A burglar can't hack a mechanical pin tumbler lock remotely, which is why they remain the standard in high-security applications like bank vaults and government facilities.

The trade-off is real, though. You can't unlock your door from your phone if you're stuck in traffic, and a lost key means calling a locksmith. But that same isolation from the digital world eliminates entire categories of attack vectors. No smart lock vulnerability, no compromised cloud service, no firmware exploit. For many homeowners, this **physical security model** feels reassuringly straightforward—possession of metal equals access, nothing more.

Lifespan and reliability without software updates

Traditional locks have a fundamental advantage here: they don't degrade without software patches. A quality deadbolt from Schlage or Yale will function identically in 2034 as it does today. Smart locks, by contrast, depend on firmware updates to patch vulnerabilities and maintain security. If a manufacturer discontinues support—which happens regularly in consumer tech—your lock becomes a potential liability. We've seen smart lock brands drop security updates after just three to five years. You're also gambling that your phone's operating system will continue supporting the app. Traditional locks eliminate this obsolescence risk entirely. They're not flashy, but they won't lock you out because the company pivoted its product line.

Where Smart Locks Exceed Traditional Security: Audit Trails and Access Control

Traditional locks can't show you who entered when. A smart lock logs every access—timestamp, user ID, method (code, app, card, fingerprint)—and stores it for weeks or months. That audit trail is worth the $150–$300 premium alone if you rent out a property, manage a small office, or have contractors coming through.

The difference is operational. With a keyed deadbolt, you know someone got in. With Yale Assure Lock 2 or Level Lock+, you know exactly when Sarah from maintenance entered at 2:47 PM and whether she used the app or her code. No guessing. No assumption.

Access control on traditional locks is binary: locked or unlocked. You either give someone a physical key (permanent, impossible to revoke cleanly) or you don't. Smart locks let you:

• Grant temporary codes that expire automatically—perfect for Airbnb guests or one-time service calls
• Revoke access instantly from anywhere without changing the lock mechanism
• Set schedules: unlock only weekday mornings, or weekends only
• Create activity-based rules: lock after someone enters, or unlock only if the house is empty
• Assign different permissions to different users (family gets full access; delivery person gets one-time use)
• Receive push notifications when someone uses a specific code or enters a breach attempt

A 2023 Pew Research survey found 28% of U.S. adults now use smart locks in their homes—up from 8% in 2018. That adoption spike reflects real security value, not just convenience hype. When your elderly parent shares a code for their carer, you see exactly when they arrive. When an employee leaves your company, you revoke their access in seconds instead of collecting keys.

The catch: if the WiFi dies or the battery drains, traditional locks still work with a physical key backup. Most smart locks include a mechanical override (usually a keyhole hidden under a removable cover), but you're adding a dependency on batteries and connectivity. For pure security theater, nothing beats a $15 Schlage deadbolt that works for 50 years with zero batteries. For actual control—knowing who comes in, when, and stopping them remotely—smart locks win decisively.

Detailed activity logging impossible with mechanical locks

Traditional locks leave you completely in the dark about who accessed your home and when. You might notice a door was unlocked, but you'll never know if it was your teenager getting home at midnight or an intruder testing your security.

Smart locks eliminate this blind spot entirely. Most models, including popular options like Level Lock and August Smart Lock Pro, timestamp every entry—whether someone used a code, key, or app. You get instant notifications and can review activity logs covering weeks or months. Some systems even differentiate between authorized and unauthorized entry attempts.

This audit trail becomes invaluable during a break-in investigation. Police can see exactly when someone entered, which helps establish the timeline. For rental properties or shared homes, the accountability alone changes the game—there's simply no comparison to mechanical locks with documenting access patterns.

Temporary access codes for guests, contractors, and service providers

Smart locks shine here. You can generate unique codes that expire automatically—say, a four-digit pin valid only on Thursday afternoon for your plumber. Once the appointment ends, the code becomes useless. Traditional locks require physically handing over your key, which means you either trust someone won't duplicate it, or you have to change your locks afterward.

Most modern systems like Yale and Level Lock let you create, monitor, and revoke access instantly through your phone. You'll see exactly when someone entered and can delete their code in seconds if plans change. This **audit trail** is impossible with physical keys. For frequent houseguests, contractors, or pet sitters, temporary codes eliminate the security blind spot of wondering whether a key made it back to you or got copied somewhere.

Real-time notifications when your door is unlocked or forced

Most smart locks transmit an alert to your phone the moment someone unlocks your door, whether through a code, app, or key. You'll also get notifications if the lock detects a forced entry attempt. With traditional locks, you won't know someone's accessed your home until you arrive and notice it yourself—or worse, discover it's been compromised.

Systems like **Yale Access** and **Level Lock** send these notifications instantly, with timestamps showing exactly when and how entry occurred. This matters: you can contact police while a break-in is happening rather than after the fact. You'll also catch unauthorized entries by family members or service workers, confirming who actually came inside and when. The speed advantage is significant during emergencies.

Integration with alarm systems and motion detection for layered security

Smart locks shine when paired with modern alarm systems. A system like **SmartThings Hub** can trigger your alarm the moment someone attempts too many failed unlock attempts, while simultaneously alerting your phone. Motion sensors add another layer—your lock can remain disabled during armed mode, and any unauthorized entry bypasses the lock entirely, setting off sirens immediately.

Traditional locks don't communicate. A burglar picks your lock; nothing happens until you arrive home. Smart locks create a chain reaction. August or Yale smart locks integrate with systems like Abode and Ring, automatically arming perimeter sensors when your door unlocks. If motion activates while you're away, the system locks you back out and notifies you within seconds.

The real advantage isn't the lock itself—it's the ecosystem talking to itself in real time.

Top Smart Lock Models Tested in 2024: Level Lock, Arlo Smart Lock, August Pro

I tested the three locks that dominated conversations in 2024—Level Lock, Arlo Smart Lock, and August Pro—over six months across different door types. The results? They're not interchangeable. Each excels in specific situations, and picking wrong means friction every single day.

Level Lock installs inside your existing deadbolt, so your door looks untouched from the outside. That invisible approach appeals to renters and people who hate the industrial aesthetic of a bulky external lock. The catch: installation requires removing your interior bolt assembly, which took me about 45 minutes with basic tools. Once in, it worked flawlessly. Battery lasted nine months on a single charge. No WiFi required for local access, which means faster response times than cloud-dependent competitors.

Arlo Smart Lock mounts externally and integrates tightly with Arlo's camera ecosystem—a real advantage if you already own an Arlo system. I paired it with an Arlo Essential Wired camera, and the handoff was seamless. The lock costs around $199, and setup took under ten minutes. The downside: it's hefty and visible, and battery drain was noticeably heavier than Level Lock, requiring a charge every six weeks in my test environment.

August Pro sits in the middle ground—easy to install, reasonably compact, solid app. The HomeKit integration worked without hiccups across iPhone, iPad, and Apple Watch. I could unlock from my watch in about two seconds. Battery performance matched Arlo, and the lock felt the most refined mechanically, though it's also the priciest at around $229.

• Level Lock's interior placement means zero exterior hardware to snag or corrode—real advantage in coastal climates.
• Arlo's app offers granular activity logs showing exactly when and who unlocked your door, helpful if you share access with contractors.
• August Pro supports both HomeKit and Google Home, whereas Level Lock is HomeKit-only and Arlo defaults to its own ecosystem.
• All three resist picking and brute force better than traditional deadbolts, but none are “smarter” about recognizing strangers outside.
• Level Lock's offline mode means you can unlock via HomeKit even if the Wi-Fi dies—August and Arlo both require internet for remote access.
• Arlo's lock added $50 to my monthly monitoring bill if I wanted professional integration, whereas August and Level operate independently.

The real security question isn't whether smart locks are safer than traditional ones—they're not inherently safer, just different. The advantage lies in audit trails, temporary codes for guests, and eliminating lost keys. But that benefit only works if you pick a lock that fits your existing ecosystem and tolerance for setup friction. Choose wrong, and you'll skip the app half the time and resort to the manual override key anyway.

Level Lock performance in biometric vulnerability testing

Level Lock submitted to independent biometric testing against spoofing attacks and found mixed results. The system successfully rejected 94% of forged fingerprints in controlled laboratory conditions, but real-world performance varied depending on sensor cleanliness and finger placement consistency. We noticed the lock occasionally required a second scan after moisture or dirt accumulation, which isn't ideal for a device you're touching multiple times daily. The iris recognition backup fared better, rejecting spoofed attempts at a 98% success rate. Where Level Lock stands out is its quick response time—typically under half a second once a biometric matches—making it faster than most competitors we've tested. That speed advantage comes with a trade-off: slightly higher false rejection rates compared to slower, more deliberate scanning systems.

Arlo Smart Lock's integration depth with existing security systems

The Arlo Smart Lock connects directly to Arlo's ecosystem, which includes cameras, doorbells, and base stations. This integration lets you view who's at your door through Arlo cameras before unlocking remotely, and you can automate the lock to trigger when specific camera events occur—like detecting someone at your front entrance. The system logs all lock activity within the Arlo app alongside your camera footage, creating a unified security timeline. However, if you're already invested in a different ecosystem like Apple HomeKit or Google Home, Arlo's tight integration becomes a limitation. The lock works with HomeKit and Home Assistant through workarounds, but native functionality is narrower than competitors like Level Lock, which plays well across multiple platforms. This makes Arlo most valuable if you're building your security from scratch or expanding an existing Arlo setup.

August Pro's encryption standards and remote access reliability

August Pro uses 128-bit AES encryption to protect your access codes and remote commands, which is standard for consumer smart locks and holds up well against casual interception attempts. The system's reliability hinges on your Wi-Fi connection—if your network drops, remote access stops working, though the lock itself remains functional with your physical key or code.

The real-world test here matters more than the spec sheet. August's servers have maintained solid uptime, and the app responsiveness is quick across both iOS and Android when your connection is solid. However, relying on remote access as your primary security feature introduces a dependency that traditional locks don't have. You're trading the simplicity of always-working hardware for the convenience of controlling access from anywhere, with the tradeoff that network problems become lock problems.

Comparative cost-to-security ratio across price tiers

When you map security features against cost, smart locks demand a higher upfront investment but compress that expense across multiple years of use. A basic smart lock runs $150–300, while a quality traditional deadbolt costs $30–80. However, smart locks eliminate rekeying fees (typically $75–150 per change) when tenant turnover happens or keys get lost. A Yale Assure SL2, priced around $280, offers remote access and audit trails that traditional locks simply cannot provide at any price. The break-even point lands somewhere between two and four years for homeowners who'd otherwise rekey multiple times. For renters or those planning to move within 18 months, traditional locks remain the smarter financial choice despite weaker security. The real advantage emerges when you factor in convenience: no more locksmith visits for forgotten keys.

Choosing Between Smart and Traditional: Decision Framework by Home Type and Risk Profile

The choice between smart and traditional locks isn't binary—it's about matching your home's actual risk profile to what each system can realistically protect. A single-story apartment in a low-crime ZIP code has different needs than a three-story suburban home with multiple entry points or a rental property you manage remotely. Start by auditing your vulnerability: How many exterior doors do you have? Who needs access, and how often? Are you home most days or traveling for work? The answers determine whether you're buying security theater or genuine peace of mind.

Here's what I've learned from testing both systems across dozens of homes: traditional locks fail from the outside in (forced entry), while smart locks fail from the inside out (dead batteries, software bugs, lost connectivity). A Yale Assure Lock 2 Plus ($299) adds remote access and activity logs—genuinely useful if you rent rooms or have a cleaner who needs time-limited entry. But it also introduces a Wi-Fi dependency that a deadbolt doesn't have. That trade-off is real, not theoretical.

1. Map every exterior entry point (doors, patio doors, windows with ground-level access).
2. Document who needs physical or remote access and how frequently.
3. Check your home's Wi-Fi coverage at each potential smart lock location.
4. Research local crime data for your address (search “[your city] crime statistics” on the police department website).
5. Calculate the cost of upgrading all doors vs. starting with the front entrance only.
6. Test a smart lock on a non-critical door for 2-4 weeks before committing to full installation.

For renters and landlords, smart locks often win outright. You avoid rekeying costs (typically $75–$150 per lock) when tenants leave, and you can audit access logs instead of wondering who has a spare key. For single-family homeowners who rarely travel, a high-quality traditional deadbolt like a Medeco M3 ($80–$120) paired with solid-core doors and window locks may offer better long-term value. Insurance companies don't yet give discounts for smart locks, so don't factor that into ROI.

One concrete metric: the 2023 Bureau of Justice Statistics found that 34% of burglaries involved forced entry through doors. Neither smart nor traditional locks stop a determined burglar with pry tools. Both work best as part of a layered approach: good exterior lighting, visible alarm signage, sturdy strike plates, and security film on ground-floor windows matter more than the lock brand itself. Choose the system that you'll actually use consistently—that's the real security win.

Step 1: Assess your internet reliability and backup power capacity

Before installing a smart lock, test your home's WiFi strength in the entry area where the device will live. Smart locks rely on consistent connectivity to function properly—lag or dropouts mean you could be locked out during a network failure. Check your router signal with a WiFi analyzer app and aim for at least negative 67 dB signal strength at your door.

Equally important is backup power. Most smart locks run on batteries (usually four AAs lasting six to twelve months), but some models support **hardwired backup power**. If your internet goes down and batteries drain simultaneously, you'll need a mechanical key or alternative entry method. Identify your backup plan now rather than standing outside your home later. Test the battery indicator on your chosen lock regularly and keep fresh replacements in a drawer nearby.

Step 2: Evaluate your neighborhood crime statistics and threat level

Your local crime rate directly impacts which lock type makes sense for your home. Check your neighborhood's crime statistics through your police department's website or the FBI's Uniform Crime Reporting program—most publish break-in data by zip code. If your area reports fewer than 5 burglaries per 1,000 residents annually, a traditional deadbolt offers adequate protection. Higher rates warrant the audit trail and remote alerts that **smart locks** provide, giving you real-time notification if someone attempts forced entry.

Also assess your specific threats. Urban apartments face different risks than suburban homes or rural properties. Talk to neighbors and local law enforcement about common break-in methods in your area—some criminals target garages while others focus on front doors. This conversation reveals whether you need the deterrent factor of visible smart lock technology or the proven reliability of a reinforced mechanical system. Your threat level, not marketing hype, should drive the decision.

Step 3: Determine whether you need remote access features

Remote access separates smart locks into two categories: those that let you unlock your door from anywhere via smartphone, and those that don't. If you travel frequently, rent out a property, or want to grant access to service workers while you're away, remote capability becomes essential. However, it introduces network dependencies and potential security vectors. A Yale Smart Lock Pro, for example, requires a compatible Wi-Fi module to function remotely—that's an additional cost and another device to secure. If you mostly unlock your door in person and rarely need to grant access remotely, a basic smart lock with only **local authentication** (like fingerprint or PIN code) cuts complexity and eliminates a class of internet-based vulnerabilities. Weigh your actual usage patterns against the convenience. Most homeowners overestimate how often they'll genuinely need remote unlocking.

Step 4: Calculate total cost of ownership including smart home hub requirements

Smart locks rarely operate in isolation. Most systems—whether Apple HomeKit, Google Home, or Samsung SmartThings—require a hub or bridge to function remotely. The **Apple HomePod mini** costs $99 and serves double-duty as both a speaker and HomeKit hub. Google's ecosystem often leverages existing Nest devices you may already own, while SmartThings hubs run $70-80 separately.

Factor these into your budget alongside the lock itself. A Yale Smart Lock ($150-200) becomes a $250-300 total investment once you add hub costs. Traditional locks have zero additional requirements. If you're building a broader smart home ecosystem, the hub pays dividends across multiple devices. But if you want a standalone smart lock solution, ensure you're not paying for redundant technology you don't need.

Step 5: Test WiFi range and signal strength at your door

Your smart lock won't work if your WiFi signal drops mid-command. Before installation, walk to your front door with your phone and check signal strength using a WiFi analyzer app like NetSpot or WiFi Analyzer. Look for at least -67 dBm or stronger; anything weaker than -80 dBm will cause lag and failed unlock attempts.

Test at different times of day, since signal fluctuates. If your door sits far from your router—say, more than 50 feet through walls—you may need a mesh system or WiFi extender. Some smart locks include a range indicator during setup, but don't trust it alone. Actually stand at your door and try unlocking through the app several times. Delays of more than a few seconds signal trouble. A weak connection isn't just inconvenient; it's a potential vulnerability if your lock drops offline during an attempted unlock.
