Smart Lock Installation in Knoxville, TN

Will your door take a smart lock?

Most retail smart deadbolts expect a modern door with a standard round bore. About one Knoxville home in three predates 1960 (33.5 percent, by Census estimates), and a door that old may hold a mortise lock or holes sized for hardware no longer sold. Those doors need a smart lock made for mortise hardware, a model that mounts over the existing deadbolt on the inside, or some carpentry first. Before you buy, photograph the edge and both faces of the door and note whether a deadbolt already sits above the knob.

In Old North Knoxville, exterior work that needs a building permit first needs a Certificate of Appropriateness from the Knoxville Historic Zoning Commission, while interior changes and work that needs no permit are not reviewed. A model that mounts on the inside leaves the street face of an original door alone. This is general information, not legal advice.

Shared entrances and rentals

Renters are more than half of Knoxville households, so many questions start with a landlord. Get written approval before changing a lock, and agree on how the landlord will get in. In a converted Fourth and Gill house, the shared front door serves every apartment, so a smart lock there needs the owner's sign-off and a working code for each tenant. A Fort Sanders brick apartment building raises the same question for its entry door.

Cold, damp and batteries

NOAA describes moderately large temperature swings and abundant precipitation in Tennessee. Cold cuts battery output, so a lock that runs fine in autumn may show a low-power warning on the first cold snap, and damp can foul an unsealed outdoor keypad. After an ice storm, do not chip ice off the buttons; let it thaw.

• Change batteries before winter, not after the warning.
• Choose an all-weather model if the door has no porch roof.
• Keep a mechanical key or another backup way in, with someone who can reach the door.

What to include in your request

In a smart lock installation request, give the door type, the lock model if you have one, and whether you rent. If other people still hold old keys, pair the install with lock rekeying. See the Knoxville page for more.
