Home locks
Rekey or replace your house locks?
Rekeying changes which key operates a compatible lock while retaining much of its hardware. Replacement changes the hardware itself. The right choice depends on condition, compatibility and whether you want different features, not simply on how many keys have been lost.
When rekeying is worth discussing
If existing locks work properly and you want to change key access, rekeying may meet that goal. Count each keyed cylinder and mention any locks that already use different keys. A door can have more than one cylinder, so a door count alone may not describe the job.
When replacement deserves attention
Loose, damaged or unsuitable hardware may need repair or replacement as well as a change of key. A request for a smart lock, a different style or a different lock function also changes the scope. Ask which parts of the existing installation can safely remain.
Ask for an option-by-option estimate
Compare the cost and result of rekeying, repair and replacement. Include keys, cylinders, installation and any necessary adjustments. If several doors should share one key, compatibility needs to be assessed before that outcome is promised.
Compare the outcome door by door
List the reason for each change: a missing key, worn operation, mismatched keys, a different finish or a new access feature. Rekeying can change key authorization without correcting every hardware defect. Replacing one damaged assembly may be sensible while compatible working locks are rekeyed. Request an itemized option for each door so a whole-house package does not hide which work is actually needed.
Check more than the new key
Try the agreed keys with the door open and then closed. Check the interior thumbturn, latch engagement and any knob or lever involved in the job. Record how many new copies were delivered and which locks share them. If an electronic keypad is also present, confirm its users separately: a mechanical rekey does not itself remove old digital credentials.
Match the repair to your reason for changing the lock
| Your objective | Discuss | Check separately |
|---|---|---|
| Stop an old key working | Rekeying compatible, serviceable cylinders | Other mechanical locks and digital credentials |
| Repair damaged hardware | Repair or replacement based on inspection | Door and frame condition |
| Add a new access feature | Compatible replacement or upgrade | Fit, power, accounts and backup access |
Before you call
- Count every keyed cylinder
- List damaged or sticking locks
- Decide which doors should share a key
- Compare complete rekey and replacement estimates
Follow-up questions
Does rekeying improve a door that is hard to close?
It changes the key combination in compatible hardware. A closing or alignment problem needs its own assessment and may remain after a rekey.
Can I replace one lock and rekey the others?
Often that is an option when the resulting keyways and hardware are compatible. Ask for a mixed repair plan based on the actual doors.
