Lock Rekeying in Las Cruces, NM

Why rekeying comes up so often here

Rekeying resets the pins inside an existing cylinder so the old keys stop working and a new key takes over. The lock body, trim and door stay as they are.

Two census figures explain why. About 41.5 percent of Las Cruces households rent, so keys change hands whenever residents do. And 40.2 percent of the city's homes date from 2000 or later; even a house that new may have passed through builders, sales agents and earlier owners, so nobody can say how many key copies are still out there.

Who rekeys, and what the rules say

• Buyers and movers. After closing or a move-in, rekey every exterior cylinder: front, back and any gate lock. If the home has an alarm that summons police or fire, city code Section 4-31 says the permit does not transfer, so a new occupant must apply within 30 days.
• Residents. New Mexico's Uniform Owner-Resident Relations Act lists owner duties in NMSA 1978 Section 47-8-20 without mentioning locks or rekeying between residents. Ask in writing, before signing, whether the locks have been changed.
• Before changing a cylinder yourself. Section 47-8-24 gives the owner a right of entry, generally on advance written notice and without consent in an emergency. Check the rental agreement and get the owner's approval first.
• Owners of rentals. Rekeying between residents makes an outgoing resident's keys stop working.
• Short-term rental hosts. Since January 1, 2026, city code Sections 16-506 to 16-512 require owners to register each unit but set no lock standard, so how often to rekey between guests is the host's call. A guest who leaves with a key is one reason to do it.

Listing your locks

List each lock by door, say which should share a key, and note any brand stamped on the lock face or key. Say whether you own or rent and whether the owner has approved the work. If a lock is worn or damaged, lock replacement may make more sense. Related pages: lock rekeying and Las Cruces.
