Short answer: Time of day, the kind of lock, how many locks, any new hardware and the drive. Ask about all five and you will not be surprised.
| Factor | What it changes |
|---|---|
| Time of day | Nights, weekends and holidays cost more. If it can wait until morning, it will usually cost less. |
| Kind of lock | A standard knob is quick. A high-security cylinder, a smart lock or a commercial lock takes longer and may need special parts. |
| How many locks | Rekeying the second and third lock on the same visit costs much less than the first. |
| New hardware | Rekeying reuses your locks. Replacing them adds the cost of the new locks. |
| Distance | Most companies cover a set area. Very rural addresses may add travel time. |
| Car keys | The key or fob and the programming, not the cutting, are most of the cost. |
Questions that keep the bill honest
- Is that the trip fee, or the total?
- What would make it cost more?
- Are parts included?
- Do you charge by the job or by the hour?
Ways to save
- Schedule it. A rekey or new deadbolt booked for a weekday costs less than an emergency call.
- Do everything at once. Have every exterior lock keyed alike on one visit.
- Make spares now. A spare house or car key costs far less than a lockout or a lost-key call.
