Do Cincinnati doors suit a smart lock?
Most smart deadbolts are made for a modern door with a standard bored hole and a separate latch. Many Cincinnati doors are older than that: Census Bureau estimates for 2024 put 41.6 percent of the city's homes in buildings from 1939 or earlier. A pre-war door with a mortise lock in its edge may need a model built for mortise locks, a retrofit unit that keeps the existing cylinder and replaces only the inside thumbturn, or new hardware altogether. Check the door thickness, the backset and the space around the current lock before buying.
In Over-the-Rhine, in the city's other local historic districts and on landmarks, exterior work goes through the Historic Conservation Office and a Certificate of Appropriateness, even when it is exempt from a building permit. A keypad on the street side of a door is visible hardware, so ask the office before fitting one. A retrofit that changes only the inside thumbturn leaves the outside as it was.
Rentals and shared buildings
Renters hold 59.9 percent of the city's occupied homes, and 13.6 percent of homes are in buildings of 50 or more units, so many residents would need an owner's approval before changing a lock. Ohio's landlord–tenant law, Revised Code Chapter 5321, has no section that deals specifically with locks, so check the lease for lock and key terms. Get any approval in writing and agree how the landlord will get a code or key. Lobby and street doors normally belong to the building. This is general information, not legal advice.
Batteries and Ohio winters
NOAA puts Ohio at about six nights a year at 0°F or lower, though the 2013–14 and 2014–15 winters averaged 18. Cold cuts battery output, so fit fresh batteries before winter and act on low-battery warnings. Whatever the model, keep a mechanical key or another backup way in, stored somewhere other than inside the house.
What to include
Give the door type and age, the current lock (knob and deadbolt, or mortise), whether you own or rent, whether the building is in a local historic district and the model you have in mind. The smart lock installation page covers the service, and lock rekeying can set the backup key. The Cincinnati page adds the city's historic district and rental rules.

What smart lock installation covers
Fitting and setting up keypad and app-controlled smart locks on doors that are compatible with them.
- A check that the lock suits your door's thickness, backset, and existing holes
- Removal of the existing deadbolt if needed
- Installation and alignment so the bolt moves smoothly
ID and proof you may access the property are checked before any work.
