Rekeying vs. Replacing Locks: Which Option Is Right for You?
Published July 16, 2026 · Last updated July 16, 2026
Rekeying is often considered when compatible lock hardware works well but the old keys should stop working. Replacement is usually considered when the hardware is damaged, unreliable, incompatible with the desired key plan, or no longer suits the property. The right option depends on lock condition, compatibility, access goals, and budget—not a universal rule.

What rekeying changes
Rekeying adjusts compatible lock hardware so a different key operates it and the previous key no longer does. It can be useful after a move, staffing or tenancy change, or when older keys are not accounted for.
Not every lock can be rekeyed into every desired arrangement. Hardware brand, cylinder type, condition, and compatibility must be evaluated.
What lock replacement changes
Replacement removes the existing lock hardware and installs different hardware. It may be appropriate when a lock is worn, damaged, unreliable, or unsuitable for the door and intended use.
Replacement also creates an opportunity to choose a different function or finish, but the new hardware must fit the door preparation and intended application.
How to compare the two options
Start with the goal: stopping old keys, correcting a mechanical problem, changing how several doors are keyed, or replacing hardware that no longer works reliably. Then document the number and type of locks involved.
A useful quote should account for compatibility, hardware condition, number of keys, number of openings, and the desired access arrangement.
Questions to ask after moving
Ask who may still have keys, whether all exterior locks operate correctly, and whether the existing hardware can support the desired key plan. Renters and managed properties should confirm who is authorized to approve changes.
Avoid assuming that every lock must be replaced or that every lock can be rekeyed. An evaluation should match the actual hardware and access concern.
Frequently asked questions
Not always. The number, type, condition, and compatibility of the locks affect the scope, so exact details are needed before comparing quotes. View pricing and the $29 service call fee.
Summary
A practical comparison of rekeying existing hardware and replacing the complete lock. The best next step depends on the actual hardware, vehicle, location, authorization, and requested outcome.
