Lock change and rekey work separates a change in key access from a change in hardware, then checks which approach fits the opening.
What this covers
- Key changes after staff departures or changes in occupancy.
- Missing keys and uncertainty about who holds copies.
- Existing cylinders that may be candidates for rekeying.
- Worn or damaged lock components that need assessment.
- Key arrangements across several business or building doors.
Rekey or replace?
Rekeying changes the internal keying of a cylinder so it operates with a different key. The surrounding lock hardware may remain. Replacement changes a cylinder, a lock assembly, or other components, depending on the condition and the intended function.
Start with the reason for the change. If keys are missing but the lock operates normally, ask whether the cylinder can be rekeyed. If the key catches, the handle feels loose, or the latch does not engage, the mechanical issue needs its own inspection.
Check the door as well as the lock. A door that sits out of position can make the lock feel stiff. Changing the keying does not alter hinge alignment or the position of the strike. Describe any need to pull, push, or lift the door while turning the key.
For several openings, map the keys before deciding on the work. One missing key may operate a shared entrance and an individual room. A management key may operate a wider group. The relevant question is which cylinders that key can turn.
Agree on the new key distribution before the work begins. Identify who receives keys, who holds any spare, and whether building management needs to be involved. Electronic credentials should be reviewed separately if the entrance also uses them.
What to have ready
- The reason for the change and any known missing keys.
- A list of doors operated by the current key.
- Current keys and photos of the hardware.
- Notes about sticking, looseness, or latching problems.
- Permission from the person responsible for the locks.
Common questions
Does rekeying mean replacing the whole lock?
No. It concerns the cylinder's keying. Whether the existing cylinder can be used depends on its design and condition.
Can several doors use one key?
That requires a review of the cylinders and the access arrangement. Do not assume different existing locks can all be placed on the same key.
Should we change keys after an employee leaves?
Review which keys were issued, which were returned, and what they operate. That gives the owner or manager a basis for deciding which cylinders to address.
