Lock Replacement in Jacksonville, FL

Older doors in a young state

Florida's housing is young: Census Bureau estimates for 2024 put 68.0 percent of homes in buildings from 1980 or later and only 1.8 percent in buildings from before 1940. Jacksonville's inner neighborhoods are older.

• Riverside, first platted in 1868, grew after the Great Fire of 1901 and is known for its bungalows.
• Avondale, developed from 1920, is mostly Mediterranean Revival.
• Springfield grew most from the early 1880s through the 1920s. Most houses are two-story wood frame, with Queen Anne, Stick style and Prairie School examples among them.

A door that old may have carried several generations of hardware, so old bores, a mortise pocket or a patched edge can all be present, and the new lock has to fit the door as it is now.

When replacement is the right call

• The key turns but the bolt or latch does not fully move.
• The lockset keeps working loose, or parts are cracked, bent or seized.
• A knob-only door needs a deadbolt, or a round knob is hard to grip and a lever would suit better.

If the hardware works and the aim is only to retire old keys, lock rekeying is the smaller job.

Historic district approvals

Chapter 307 of Jacksonville's Ordinance Code covers historic preservation, and Section 307.106 sets the procedures and criteria for a Certificate of Appropriateness (COA). Springfield is both on the National Register and locally designated. The city's FAQ says a COA comes before exterior work on a historic district property or local landmark, and before interior work that changes windows or exterior doors. It puts staff COAs at a week or two and Historic Preservation Commission review at least a month, and warns that work begun without one may receive a violation. The city's Land Development Map shows by address or real estate number whether a property is covered. This is general information, not legal advice.

What to send

• Photos of the lock and door edge, inside and out.
• The door's thickness and material, and whether it is original.
• Whether the house sits in a historic district.
