Smart locks for apartment doors

Updated

Look at your lock before you look at smart locks. If your apartment door has a normal deadbolt above a separate knob or handle, you have options, and a retrofit lock like the August Wi-Fi Smart Lock can keep your key working. If it has one tall lock body set into the door edge, a mortise lock, the makers we checked say their smart locks will not fit.

A deadbolt with a thumb turn inside, and a knob or handle below itSingle cylinder deadboltRetrofit locks and most smart deadbolts

One tall plate on the door edge, handle and deadbolt in one unitMortise lockNot the August or the Yale locks, per their support pages
Only one hole, a handle with a key in itHandleset or keyed lever, no deadboltA lever style smart lock, not a deadbolt

August's support page says its smart locks only fit single cylinder deadbolts, and lists mortise locks and double cylinder deadbolts as not compatible. Yale's support page says a mortise prepped door is not compatible with its locks.

The smart lock that keeps your key

People search for a smart lock that keeps the key they already have. That is a retrofit lock. The August Wi-Fi Smart Lock fits over the inside of a single cylinder deadbolt and turns it with a motor. The outside of the door and every copy of the key stay the same. For an apartment that matters, because the building manager's key still works.

The caveats are real. There is no keypad unless you buy one. August's own FAQ says up to 3 months of battery with WiFi on, and owners report less in some homes. And it only works as well as the deadbolt it turns. Do the free throw check first.

If you can swap the whole deadbolt

With written permission, a full smart deadbolt gives you a keypad. Measure first. The common size is 1-3/8 to 1-3/4 inches thick, a 2-3/8 or 2-3/4 inch backset and a 2-1/8 inches hole. Older buildings do not always match. Our fit checker compares your numbers with the listings.
