Rekeying reuses your existing hardware and changes the internal pins so old keys stop working — usually faster and cheaper than new locks. The calculator estimates your cost based on lock count, residential vs. commercial property, and whether you still have a working key.
How much does it cost to rekey a house?
For most single-family homes, the cost to rekey a house lands in a typical range that covers a locksmith service call plus a per-lock rekey fee. Smaller homes with two doors are on the lower end; larger homes with 5+ entry points, a gate lock, or smart hardware sit higher. The calculator gives you a personalized estimate without exposing a generic price chart that may not match your situation.
What affects rekey service cost?
- Number of locks being rekeyed
- Residential vs. commercial property
- Whether you have a working key
- Keyed-alike vs. separate keys
- Lock brand and security grade
- After-hours or emergency visits
Rekey cost by number of locks
The more locks on the visit, the lower the average rekey locks cost per lock — because the service call is shared across all of them. A 1-lock visit costs more per lock than rekeying 5 locks in the same appointment. Enter your lock count in the calculator for a tailored estimate.
Residential vs. commercial rekey
Commercial rekey service cost is higher than residential because commercial-grade locks (mortise, IC core, high-security cylinders) take longer to service and use pricier pins. If your property is a storefront, office, or multi-tenant building, choose “Commercial” in the calculator for an accurate lock rekey cost.
Do you have the current key?
If you have a working key, the locksmith can rekey directly — fastest and cheapest. If the key is lost or doesn’t turn, the lock has to be picked or disassembled first, which adds a small per-lock surcharge. The calculator factors this in automatically.
When rekeying is better than replacing locks
- You moved into a new home and want old keys deactivated.
- A roommate, tenant, or contractor returned (or didn’t return) a key.
- You want all doors keyed alike with one master key.
- Your locks are in good condition — only the key needs to change.
Replacing locks makes more sense when hardware is damaged, outdated, or you want to upgrade to a smart lock. See our general locksmith cost guide for a broader comparison.

Frequently asked questions
How much does it cost to rekey a house?
Rekeying a typical house usually falls in a $95–$280 range. Expect a service-call fee around $65–$120 plus roughly $25–$55 per residential lock. Homes with 3–5 doors land in the middle of that range; larger homes or commercial-grade hardware cost more.
What is the average rekey service cost?
Most homeowners pay between $120 and $220 for a standard rekey visit covering 2–4 locks. The exact rekey locks cost depends on lock count, lock type, and whether you still have a working key.
Is rekeying cheaper than replacing locks?
Almost always. A lock rekey cost reuses your existing hardware and only changes the internal pins, so old keys stop working. New lock installs cost more because you pay for parts plus labor.
Can I rekey all my locks to one key?
Yes — as long as the locks are the same brand/keyway. Ask the technician for 'keyed alike' service and one key will open every rekeyed lock.
Do I need to have the current key?
No, but it lowers the cost to rekey locks. Without a working key, the technician has to pick or disassemble the lock first, which typically adds $15–$40 per lock.
How long does a rekey take?
Most residential rekeys take 10–20 minutes per lock once the technician is on site. A full-house visit is usually finished within an hour.
