Are Smart Locks Safe? A Locksmith’s Honest Take for PA Homeowners

Let’s cut to the chase: you’re thinking about upgrading to a smart door lock, but you’re worried. Can these things actually be hacked? What happens when the battery dies at midnight? And are they really safer than the deadbolt your house came with?

Smart locks offer convenience, keyless entry, and remote access, but they aren’t a one-size-fits-all solution. Here’s what you need to know before you make the switch.

The Short Answer: Yes, But With Conditions

Trusted smart locks—Schlage, Kwikset, Yale, August—are generally safe. They prevent lock picking, let you lock remotely, and offer built-in safety measures like auto-lock and activity monitoring. Many also connect with home security systems and smart home devices.

Trade-offs: They rely on batteries, WiFi, and updates. Poor connectivity or neglected maintenance can make gaining access tricky. Choose well-built smart locks with backup keys or built-in emergency systems.

Best setup: Combine a smart lock with a Grade 1 traditional deadbolt. Enjoy keyless convenience without losing the reliability of standard locks, safe for residential use.

Why Smart Locks Actually Make Your Home Safer

No Keyhole Means No Picking

Smart locks eliminate traditional keyholes, removing a major vulnerability of standard locks. Skilled burglars can pick a Grade 1 deadbolt lock quickly, but keyless smart locks stop that entirely. Some models include a high-security backup cylinder for emergencies.

You Know Exactly Who’s Entering (and When)

Many smart locks log every entry. Track when kids arrive, contractors stop by, or guests use temporary codes. For rentals or Airbnb hosts, this access control adds real security and peace of mind.

No More Lost Keys or Lockouts

With smart locks, physical keys aren’t necessary. Create unique codes for household members, temporary codes for visitors, and revoke access instantly. No more hiding spare keys or worrying about unauthorized copies.

Auto-Lock and Remote Control

Ever left for vacation and spent the first day wondering if you locked the front door? Smart locks solve that. Most models auto-lock after a set time, and you can check or lock your door remotely through an app. It’s one less thing to worry about.

Plays Nice With Home Security Systems

If you’ve already got cameras, alarms, or smart lights, modern smart locks integrate seamlessly. Some setups can trigger “away mode” when everyone leaves—lights dim, thermostat adjusts, and the door locks automatically. It’s convenient, and it adds another layer of security.

The Risks You Should Actually Worry About

Yes, Smart Locks Can Be Hacked (But So Can Your Front Door)

Smart locks can be hacked, but physical break-ins are far more common. According to FBI burglary statistics, 55.7% of burglaries involved forcible entry, 37.8% were unlawful entries where no force was used, and 6.5% were attempted forcible entries. Most burglars still rely on kicking doors or breaking windows rather than bypassing encryption.

To keep smart locks safe:

• Choose reputable brands with strong encryption (AES 128- or 256-bit).
• Secure your WiFi network with a strong password and WPA3 encryption.
• Enable two-factor authentication on the lock’s app.
• Keep firmware and apps updated.

Many smart locks also include a built-in backup system like Bluetooth, a physical key, or an external battery port for emergencies.

Batteries Die, WiFi Drops, and Apps Glitch

Here’s where smart locks get frustrating: they rely on technology that can fail. Batteries typically last 6-12 months, but Pennsylvania winters drain them faster. Cold temperatures can significantly reduce battery performance—alkaline batteries may provide only 15% of their normal capacity in extreme cold below -10°C.

If you’re not tech-savvy or if you live in a rural area with an unreliable internet connection, a smart lock might cause more headaches than it solves. A traditional deadbolt doesn’t need WiFi, batteries, or software updates. It just works.

Are Smart Locks Safe and as Strong as Regular Deadbolts?

The Physical Security Is the Same (When Done Right)

Here’s something most people don’t know: smart locks follow the same security standards as traditional locks. They’re rated by the American National Standards Institute (ANSI) and the Builders Hardware Manufacturers Association (BHMA) using a three-tier grading system:

• Grade 1: Highest residential security (commercial-grade strength)
• Grade 2: Solid for most homes
• Grade 3: Basic security, not recommended for exterior doors

A Grade 1 smart lock like the Schlage Encode or Kwikset Halo is just as physically secure as a Grade 1 traditional deadbolt. Same bolt strength, same strike plate, same resistance to forced entry.

The Real Difference: Picking vs. Hacking

Bottom line: Both lock types offer robust security. Smart locks carry cybersecurity risks; traditional deadbolts face lock-picking risks. Pick your poison.

Who Should Get a Smart Lock (and Who Shouldn’t)

Smart Locks Are Best For You If You:

Smart locks are ideal for homeowners who are comfortable managing apps and smartphones, use keyless entry regularly, and want to track when family members or guests enter. They’re also a great choice for managing rentals or providing temporary access codes, and for those who appreciate auto-lock features or integration with smart home systems. Reliable WiFi helps, but Bluetooth-only models work well if connectivity is limited.

Traditional Deadbolts Are Better If You:

Traditional deadbolts are better suited for those who prefer simplicity and minimal technology. They are a smart choice for rural homes with weak WiFi, older homes with non-standard doors, or situations where door modifications aren’t possible. Deadbolts also provide a reliable solution for anyone who wants a lock that works indefinitely without updates, battery swaps, or app management.

The Hybrid Approach: Best of Both Worlds

Many homeowners choose both: a smart lock for convenience and a Grade 1 traditional deadbolt as backup. This keeps the lock secure even if the smart lock’s battery dies, the app malfunctions, or WiFi connectivity is lost. It’s a slightly higher upfront cost, but it combines convenience with reliable residential lock security.

How to Choose a Safe Smart Lock

Stick With Brands You’ve Actually Heard Of

Don’t cheap out here. The no-name smart locks on Amazon with suspiciously low prices? I’ve seen more of those fail in the first year than I can count. Stick with:

• Schlage (Encode, Sense)—100+ years of lock manufacturing
• Kwikset (Halo, Obsidian)—solid security, good track record
• Yale (Assure Lock)—established lock manufacturer founded in 1868
• August (Smart Lock Pro)—owned by Assa Abloy, a reputable parent company

Look for Strong Encryption and Security Features

This is where the technical stuff matters:

• AES 128-bit or 256-bit encryption (same level as banks use)
• Bluetooth Low Energy (BLE) 5.0 or newer
• Two-factor authentication on the companion app
• TLS/SSL encryption for cloud communication

If the product page doesn’t clearly state these security features, walk away.

Check the ANSI Rating

Pick a smart lock with the right rating: Grade 1 for exterior doors, Grade 2 for most homes. Avoid Grade 3—looks can be deceiving, and the physical security is too weak.

Make Sure There’s a Backup Plan

Always choose a smart lock with a built-in backup system, like a mechanical key or external battery port. Some models retrofit over your existing deadbolt, keeping a physical key as a reliable fallback.

Bluetooth Should Work Without WiFi

Smart locks should work offline via local Bluetooth. If your WiFi network drops, you can still lock or unlock your door safely without relying on the cloud.

DIY vs. Professional Installation (Why It Matters)

Common DIY Mistakes We See All the Time

I’m not saying you can’t install a smart lock yourself; plenty of handy homeowners do it just fine. But I am saying we get a lot of calls from people who tried DIY and ran into problems:

• Misaligned bolt—the lock doesn’t fully extend into the strike plate, leaving a security gap
• Weak WiFi signal at the front door—they didn’t test connectivity before drilling holes
• Wrong backset or door thickness—the lock doesn’t fit properly, leaving gaps or binding
• App setup errors—weak passwords, no two-factor authentication, firmware never updated
• Skipped strike plate reinforcement—long screws into the door frame studs are critical for security

Pennsylvania-Specific Factors We Always Consider

• Cold winters reduce battery life—we tell every client to check batteries before November. Extreme cold can reduce alkaline battery performance by up to 85%, so consider lithium batteries for better winter reliability.
• Older homes often have non-standard doors—thicker frames, odd measurements, multiple layers of paint, and wood
• Rural areas have weak WiFi—Bluetooth-only models might be better than WiFi-dependent systems
• Power outages are common—always keep a mechanical backup key or external battery option

Smart Lock Security Best Practices

Digital Security

For digital security, always use a secure WiFi network with WPA3 encryption and a strong password. Enable two-factor authentication on your smart lock app, and create unique access codes for each user rather than sharing the same code.

Temporary codes for guests should be set up carefully and deleted as soon as they are no longer needed. Regularly updating the firmware and app is essential, as manufacturers release patches to fix security vulnerabilities and keep smart locks safe.

Physical Security

Physical security is just as important. Reinforce your door frame with 3-inch screws into wall studs to prevent forced entry, and use a solid-core door, since hollow doors are easily compromised regardless of the lock quality. Installing a front-door camera allows you to monitor access attempts, and choosing a smart lock with tamper alerts ensures you’ll be notified immediately if someone tries to force it.

The Bottom Line: Should You Trust Smart Locks?

Here’s My Honest Assessment After 25+ Years

Smart locks are safe when:

• You’re comfortable with smartphone apps and basic troubleshooting
• Your home has reliable WiFi (or you choose a Bluetooth-only model)
• You pick a Grade 1 smart lock from Schlage, Kwikset, Yale, or August
• You maintain firmware updates, check batteries, and follow security best practices
• You accept the trade-off: convenience and monitoring in exchange for battery maintenance

Smart locks are not safer than traditional Grade 1 deadbolts if:

• You choose a cheap off-brand lock with weak encryption
• You neglect maintenance (old firmware, dead batteries, weak passwords)
• Your WiFi is unreliable, or you lack tech support
• You’re not comfortable managing the technology

The safest option? Hybrid setup. Smart lock for daily convenience and monitoring, traditional Grade 1 deadbolt as backup. That gives you the best of both worlds.
