Rekeying vs. Replacing Locks: A Complete Guide for Farmington Homeowners
Rekeying costs $25–$50 per lock. Replacing costs $100–$250 per lock. The right answer isn’t always the cheaper one — it depends on what you’re trying to solve. This guide covers every scenario a Farmington homeowner encounters.
What Rekeying Actually Does
Rekeying changes the internal pin configuration of a lock cylinder. A locksmith swaps the key pins so your old keys no longer work and new keys do. The lock body, deadbolt mechanism, and all hardware stay the same. Rekeying solves the “who has my key” problem — not the “this lock is too weak” problem.
When to Rekey
- Just bought a Farmington home and locks are in good condition
- Lost a key and don’t know where it is
- Ended a relationship and partner had a key
- Roommate moved out with a copy of your key
- Hired and fired a contractor, housekeeper, or dog walker with a key
- You want all locks keyed alike — one key opens everything
- Rental turnover — new tenant’s keys only
When to Replace
- Lock is worn, stiff, or hard to operate — mechanical wear rekeying won’t fix
- Lock is Grade 2 builder-grade and you want a security upgrade
- Lock was damaged in a break-in attempt
- You want smart lock or keypad entry — requires new mechanism
- Lock is 20+ years old and has never been serviced

Keying Alike: One Key for Every Door
When rekeying multiple locks, ask your locksmith to “key alike” — setting all locks to the same key. Front door, back door, garage entry — all one key. Many Farmington homes have separate keys from previous owners. Consolidating to a single key at rekeying costs nothing extra and ends daily key-ring fumbling for good.
