Rekeying changes the internal combination of a compatible lock cylinder so that old keys no longer operate it. It is different from installing a new lock. Whether it makes sense depends on the hardware's condition, security needs and how many doors need to work with the same key.
Rekeying and replacing are not the same job
During a typical rekey, a locksmith changes the relevant parts of the existing cylinder to match a new key. The housing, knob or deadbolt may stay in place. Replacing a lock installs new hardware. Rekeying is attractive when the lock is sound and you simply need to stop old keys working. Replacement can be appropriate when the existing lock is damaged, too worn or lacks features you need.
| Situation | What to ask about |
|---|---|
| Just moved in | Rekey existing compatible locks; check all exterior doors. |
| Former tenant has keys | Confirm authorization and coordinate rekeying or access changes. |
| Deadbolt sticking or damaged | Diagnose repair versus hardware replacement. |
| Want keypad entry | Ask about smart-lock fit, installation and access management. |
What affects the cost to rekey locks?
Number of cylinders, type and brand of lock, whether all locks can use one key, travel charges and whether the locks need repairs can all change the estimate. Ask whether a price is per cylinder, per door or for the visit, and how many new keys are included. A low advertised starting price is not necessarily the final invoice.
Can different doors use the same new key?
Sometimes. Cylinders usually need compatible keyways and appropriate hardware. If you've mixed lock brands across several entrances, a locksmith should inspect them before promising a single-key solution. Don't assume every smart lock or security cylinder uses an ordinary rekeying method.
Santa Fe homeowners and property managers: what to prepare
- List each exterior entrance, garage-access door and rental unit involved.
- Say if the property is currently occupied and whether a tenant or manager controls access.
- Count how many working keys exist and whether any are unaccounted for.
- Ask the technician to inspect existing deadbolts and strike alignment rather than automatically replacing every part.
A historic home near downtown and a newer residence on the Southside can have different hardware; the individual lock condition is what matters. Service eligibility and travel must be confirmed, not inferred from the address alone.
Frequently asked questions
Will my old keys stop working after rekeying?
For a properly rekeyed cylinder, the previous key combination should no longer operate that cylinder. Check all intended doors before the technician leaves.
Can I rekey a lock myself?
Some lock products offer consumer rekeying methods, but compatibility and correct operation matter. When multiple exterior doors or tenant access are involved, professional evaluation may be worthwhile.
Can all my doors share one key?
Only when the hardware and keyways are compatible. Tell the locksmith which doors you want keyed alike.
