What does it typically cost to rekey a lock?
Lock rekey cost is usually split into two parts: a per-lock labor charge and a one-time service or trip fee for the locksmith coming to you. The per-lock labor to rekey a standard residential pin-tumbler lock commonly falls in the $15 to $50 range, while the trip or service fee for a mobile locksmith often runs about $50 to $150 depending on your area and the time of day.
Because the trip fee is charged once per visit, rekeying several locks at the same appointment lowers your average cost per lock. A single-lock visit might total roughly $75 to $200, while rekeying four to six matching locks in one trip can spread the service fee across all of them and bring the per-lock figure down noticeably.

- Per-lock labor for a standard residential lock: roughly $15 to $50 each, as an estimate
- Service or trip fee: often about $50 to $150 per visit, varies by area
- Single-lock visit total: commonly around $75 to $200, as an estimate
- Multiple matching locks in one trip: lower average cost per lock
What is rekeying, and why is it usually cheaper than replacement?
Rekeying means a locksmith opens the lock cylinder and changes the internal pins (the small spring-loaded pin stacks inside a pin-tumbler lock) so the lock works with a new key and no longer works with the old one. The lock body, deadbolt, knob, and strike plate all stay in place; only the key that operates the lock changes. In short, rekeying reconfigures the cylinder rather than swapping the hardware.
Replacement, by contrast, means removing the existing lock hardware and installing a brand-new lockset. That adds the cost of the new lock itself plus more labor, which is why replacement is typically more expensive than rekeying when the existing hardware is in good condition.
A common money-saving option is having a locksmith rekey several locks to match a single key (keying alike), so one key opens your front door, back door, and garage entry. The pins are set to the same combination across each cylinder, which is convenient and avoids buying matched hardware sets.
- Rekey: change the cylinder pins so a new key works and the old key does not
- The physical lock stays in place; only the working key changes
- Replace: remove old hardware and install a new lock, which usually costs more
- Keying alike lets one key operate several rekeyed locks
What factors affect your lock rekey cost?
Several variables move the price up or down within these typical ranges. The biggest is how many locks you need done and whether they share a compatible cylinder type, because the per-visit service fee is spread across all the locks rekeyed in one appointment.
Lock type and brand matter too. Standard residential pin-tumbler deadbolts and knob locks are the most straightforward to rekey. High-security cylinders, certain commercial locks, and some smart-lock cylinders can require special pins, restricted keys, or extra time, which raises the labor portion. Timing also plays a role: after-hours, weekend, or holiday visits often carry higher service fees than a scheduled weekday appointment.
Finally, location and accessibility affect the trip fee. A longer drive, difficult parking, or a lock that is worn, painted over, or partly seized can add time. If a cylinder is damaged beyond a clean rekey, a locksmith may recommend replacement instead, which changes the cost basis entirely.
- Number of locks rekeyed in one visit: more locks means a lower cost per lock
- Lock type and brand: standard versus high-security or specialty cylinders
- Whether you want locks keyed alike to one shared key
- Time of service: weekday appointment versus after-hours or weekend
- Your location, drive distance, and how accessible the locks are
- Lock condition: worn or damaged cylinders may need replacing instead
Rekey vs. replace: which is the better value?
If your existing locks are in good working order and you simply want to control who has a key, rekeying is usually the more economical choice, because you keep the hardware you already own and pay mainly for labor. Common reasons people rekey include moving into a new home, losing a key, ending a roommate or tenant arrangement, or wanting all exterior doors on one key.
Replacement makes more sense when the hardware itself is the issue. If a lock is corroded, mechanically failing, or outdated, or you want to upgrade to a different style, finish, or a higher security grade, installing new locks can be the better long-term value even though the upfront cost is higher.
A practical way to compare is total cost per door. Rekeying typically involves the service fee plus modest per-lock labor. Replacement adds the price of each new lockset on top of installation labor. For a few doors with sound hardware, rekeying is often the lower-cost path; for failing hardware or a security upgrade, replacement can be worth the difference. A locksmith can assess your specific locks and give you a free quote for both options.
- Choose rekey when hardware is good and you just need new keys or one shared key
- Choose replace when locks are damaged, outdated, or you want an upgrade
- Rekey cost is roughly the service fee plus per-lock labor, with no new hardware to buy
- Replace cost is roughly installation labor plus the price of each new lockset
How to get an accurate rekey estimate and avoid surprises
Because rekey pricing depends on details, the fastest way to a real number is to share a few specifics up front: how many locks you need rekeyed, the lock brand or type if you know it, whether you want them keyed alike, your location, and when you need it done. With that, a locksmith can give you a clear estimate before any work begins.
Ask whether the service fee is separate from per-lock labor and whether it is waived or rolled in when work is performed; this is the single biggest source of confusion on a final bill. Confirm the per-lock rate, ask if there is any added charge for high-security or specialty cylinders, and get the estimate before the locksmith starts so there are no surprises.
