Moving into a Las Cruces home often means you do not know how many copies of the old keys exist. A former owner, tenant, contractor, neighbor, or property manager may still have one. Rekeying can be a practical way to reset access without replacing every lock, provided the existing hardware is in usable condition.
Make a door list first
Walk the property and note front, back, side, patio, garage-to-home, gate, mailbox, shed, and casita doors. Decide which openings should use one key and which should stay separate. If a lock is loose, hard to turn, or visibly worn, flag it for repair or replacement rather than assuming rekeying alone will solve it.
| Property situation | Often makes sense | Also check |
|---|---|---|
| Bought an existing home | Rekey exterior and important interior access | Garage, side gates, casita, and mailbox |
| Moved into a rental | Confirm landlord’s access plan | Lease rules and emergency key storage |
| Changed tenants | Rekey between occupants | Do not rely only on collecting old keys |
| Lost a key | Rekey affected locks | Whether the lock is worn or damaged |
Rekeying vs. replacing
Rekeying keeps compatible hardware and changes the key that operates it. Replacement is better when the lock is damaged, the fit is poor, the keyway is obsolete, or you want a new deadbolt, finish, grade, or smart feature. We can review both options before the work so the plan fits the property.

Rekeying questions
What does rekeying change?+
Rekeying changes the internal pin configuration so the old key no longer operates the lock, while the existing lock hardware can remain in place if it is in good condition.
Should every exterior door be rekeyed?+
Review every exterior entry, garage-to-home door, side gate, and mailbox or outbuilding lock that should be included in the new access plan.
