Lock Replacement in Lexington, KY

Newer doors and older doors

In the Census Bureau's 2020–2024 estimates, 27.2 percent of Lexington's homes were built in 2000 or later. On a door that new, replacing a worn lock comes down to matching the bore hole and backset, so measure both or bring the old lock along.

Some of the city's older doors sit in its H-1 historic overlay districts. Lexington has had local historic districts since the mid-1950s, and the city's list includes Gratz Park and South Hill along with Ashland Park, Bell Court and Western Suburb. An original door in one of them may carry a mortise lock. Putting a modern deadbolt in its place can mean re-cutting the door, whereas a mortise replacement sized for the existing pocket can keep the door as it was.

Replacing hardware in an H-1 district

Exterior changes to a property in an H-1 overlay need a Certificate of Appropriateness under Section 13-7 of the Lexington-Fayette zoning ordinance. The ordinance carves out routine maintenance: repairs to existing features, or swaps for identical pieces, that leave the exterior looking unchanged.

The city's Review of Elements chart treats door replacement in tiers. Staff may approve a replacement door of similar materials and configuration; removing a door or installing a new one goes to the Board of Architectural Review. If a change would show from the street, such as a new handle set, ask the Division of Historic Preservation whether approval is needed before you order it. This is general information, not legal advice.

Choosing the replacement

• On a newer door, give the bore and backset, or bring the old lock.
• On an older door, say whether it has a mortise lock and whether the trim is original.
• If the worry is lost or unreturned keys rather than a failing lock, rekeying keeps the lock you already have.

Older housing is more common in Louisville, where 36.5 percent of homes predate 1960. The lock replacement page covers the service, and Lexington has the rest of the city's notes.
