Frequently Asked Questions About Smart Deadbolts

Does a Best Selling Compact August Smart Lock replace the exterior deadbolt keyhole?

No, it mounts strictly over your existing interior thumbturn. That means you keep your original keys, exterior cylinder, and strike plate completely intact. This design makes it an ideal retrofit solution for apartments or rental properties where altering exterior door hardware violates lease agreements.

How does the lock operate if the batteries die unexpectedly?

You can always unlock your door manually from the outside using your traditional brass physical key. Because the exterior lock hardware remains unchanged during installation, a dead battery will never leave you locked outside. The mobile app also sends low-battery notifications to your smartphone well before power runs out.

Can you integrate an August smart lock with other entry security systems in 2026?

Yes, these smart deadbolts connect smoothly with voice assistants like Alexa, Google Assistant, and companion wireless accessories. Many homeowners coordinate their smart lock activity with wired vs wireless doorbell setups to verify visitors before remotely retracting the latch. Remote access generally requires built-in Wi-Fi or a dedicated plug-in Wi-Fi bridge.

Will this retrofit lock fit standard American exterior residential doors?

Yes, it is engineered to fit most standard single-cylinder deadbolts on doors measuring 1-3/8 inches to 1-3/4 inches thick. It accommodates standard backset distances of either 2-3/8 inches or 2-3/4 inches without requiring drilling or door modifications. Double-cylinder deadbolts and mortise locks are not compatible with this retrofit style.

How does DoorSense prevent the deadbolt from locking while the door is open?

DoorSense uses an integrated magnetic sensor mounted on your doorframe to verify whether the door is completely shut. If the sensor detects that the door is still open, it prevents the auto-lock motor from throwing the deadbolt into the doorframe. This smart detection protects both your door jamb and motorized lock gear from accidental impact damage.

Can guests use numeric PIN codes or fingerprints without downloading the smartphone app?

Yes, pairing your lock with a Yale or August wireless keypad provides PIN code entry or biometric fingerprint scanning. You can assign unique temporary or recurring guest codes directly inside the app, which visitors enter right at the keypad. This feature allows dog walkers, cleaners, or rental guests to enter easily without creating an app account.
