Yale Assure Lock 2 (Z-Wave)
Best Overall for Fire ExitPros
- UL listed for fire exit safety
- Physical thumb-turn always works
- Works with most smart home hubs
Cons
- Requires Z-Wave hub
- No built-in Wi-Fi
The Yale Assure Lock 2 is the only smart lock on this list with a UL 1034 listing for burglary resistance and a fail-safe mechanism that ensures the lock retracts when power is lost. Owner reviews on retailer sites consistently mention the reliability of the thumb-turn for quick egress, even during a power outage. The lock uses standard 4x AA batteries that last around 12 months with normal use.
Installation is straightforward on standard doors, and the Z-Wave connectivity means it integrates with systems like SmartThings and Ring Alarm. The lack of built-in Wi-Fi is a minor inconvenience, but it improves battery life and security. For fire exit compliance, this is the safest choice.

Best Retrofit for Fire ExitPros
- Works with existing deadbolt
- Easy twist-to-open egress
- Built-in Wi-Fi, no hub needed
Cons
- No UL fire rating
- Battery life shorter than Yale
The August Wi-Fi Smart Lock mounts over your existing deadbolt, so you keep your current key and lock cylinder. This is important for fire exits because you can always unlock the door with the physical key if the smart lock fails. Owner reviews highlight the smooth twist knob that allows quick exit without fumbling.
The lock connects directly to Wi-Fi and works with Alexa, Google, and Apple Home. Battery life is around 6 months, which is shorter than dedicated fire-rated locks. For retrofit applications where you want smart access without replacing the entire lock, this is a solid choice.

Cons
- Higher price point

The Schlage Encode Plus is built to BHMA Grade 1 standards, the highest residential security grade. It features a built-in alarm that sounds if someone tries to force the lock, which adds a layer of safety for fire exit doors that might be left unlocked. The thumb-turn on the interior provides quick egress, and the Apple Home Key feature works even if your phone battery is dead.
Owner reviews praise the robust build quality and reliable Wi-Fi connection. The lock is larger than some competitors, so check your door clearance. For Apple users who want the convenience of NFC unlocking without sacrificing fire exit safety, this is a top choice.
Ring Smart Lock Pro
Best for Ring Alarm UsersPros

The twist knob egress is intuitive, and the lock supports auto-unlock when you arrive home. Owner reviews note the convenience of the Ring ecosystem integration.
The lock requires the Ring Alarm Bridge for connectivity, which adds to the cost if you don't already have one. Battery life is average at 6 months. For existing Ring users who want a smart lock that integrates with their alarm system, this is a practical option.
Kwikset Halo Touch
Best Simple TouchscreenPros
- Touchscreen works without app

The physical thumb-turn on the interior provides reliable egress, and the SmartKey feature lets you re-key the lock yourself if needed. Owner reviews appreciate the straightforward setup and the ability to use codes for guests.
The lock connects directly to Wi-Fi and works with Alexa and Google Assistant. The touchscreen can be less responsive in very cold weather, which is a consideration for exterior fire exits. For users who want a no-fuss smart lock with a physical key backup, this is a reliable choice.
What to Check Before Buying a Smart Lock for a Fire Exit
Fire exit doors have specific requirements that standard smart locks may not meet. First, confirm your local fire code allows electronic locks on egress doors. Many codes require a manual release mechanism that works without power. Look for locks with a physical thumb-turn or twist knob on the interior side. Avoid models that rely solely on electronic or app-based unlocking for egress.
Check the lock's UL or ANSI certification. UL 1034 listing indicates the lock has been tested for burglary resistance and fail-safe operation. BHMA Grade 1 or 2 certification ensures the lock can withstand repeated use. Also verify that the lock does not require any special tools or keys to open from the inside during a power outage.
Mistakes to Avoid
One common mistake is installing a smart lock that requires a key or code to exit. This violates most fire codes and can be dangerous in an emergency. Always choose a lock with a mechanical thumb-turn or lever that does not depend on batteries or connectivity.
Another mistake is ignoring door clearance. Some smart locks have large escutcheons that can interfere with door closers or panic hardware. Measure your door and frame before purchasing. Finally, avoid locks that do not offer a physical key backup for the exterior, as this can leave you locked out if the electronics fail.
