Start with the problem you need to solve
Describe the result you want before selecting a product or service. A key that sticks is an operating fault. A previous occupant who may still have a copy of a key is an access concern. A wish to fit a different kind of lock is a hardware requirement. These can overlap, but they are not interchangeable. If more than one applies, say so at the start so the proposed work can be discussed as a defined set of requirements.
Repair: restore suitable existing hardware
Repair work focuses on a fault in the lock or related door hardware. Tell the locksmith what the key, handle or latch does and when the problem appears. Keeping the existing hardware can be appropriate where it remains suitable and its operation can be restored. A repair does not, by itself, mean old keys have been retired. If control of those keys matters, include that as a separate requirement when discussing the job.
Rekey: change which keys operate the lock
Rekeying changes the key arrangement of compatible existing hardware. It can be useful after moving in, a change of occupants or uncertainty about keys that are no longer accounted for. It does not automatically correct a mechanical fault or change the type of lock fitted. The hardware and its condition need to be checked. If several doors should use the same key, explain the intended arrangement so compatibility can be considered across the affected entrances.
Replace or install: change the hardware
Replacement means changing existing hardware. Installation may also introduce a new fitting, such as a deadbolt or a smart-lock arrangement. Explain the door, existing fittings and how access should work. New hardware should be selected around those requirements rather than its appearance alone. If you already have a product in mind, identify it before arranging the work so suitability and installation requirements can be discussed.
Questions to ask before agreeing the work
A clear scope helps you understand what the proposed job will change and which concerns will remain. Discuss the affected entrances, the intended key arrangement, the existing fault and the proposed price. Where new hardware is suggested, ask how it relates to the problem and whether other doors are affected. Before the visit ends, confirm which locks were included and check the completed operation.
- Which entrances and keys are included?
- Is the concern a fault, old keys, different hardware or a combination?
- What is included in the proposed price?
- How will the finished arrangement be checked?
