Keypad and app locks are popular in DC for good reason: no keys to lose, codes for guests and cleaners, and a log of who came in. Most install on a standard deadbolt hole in minutes. Older doors need a closer look.
Check 1: is there a standard deadbolt?
Most smart locks replace a regular deadbolt. If your door has only a mortise lock, you can add a deadbolt above it for the smart lock, or use a model made for mortise doors.
Check 2: door thickness and backset
Historic doors are often thicker than the modern standard. Many smart locks have a thick-door kit; some do not.
Check 3: does the bolt throw freely?
This is the big one. If you have to push or pull the door to lock it, a motorized lock will jam and drain batteries. Wood doors swell in DC summers, so the strike and latch need to be aligned before the lock goes on. A locksmith does this as part of smart lock installation.
Condos and rentals
Check building rules. Some associations restrict what can be changed on the hallway side of a unit door.
