How to Rekey Locks
How to rekey locks: a locksmith adjusts the lock’s cylinder so a new key works and the old key no longer does. The existing lock hardware usually stays in place; replacing it is a lock change.

What Does Rekeying a Lock Change?
Rekeying changes which key operates a compatible lock. A locksmith adjusts the lock cylinder so it responds to a new key and stops responding to the previous key. The lock’s exterior hardware generally remains in place, so rekeying is different from installing a new lock.
This can be useful after a move, a change in who has access, or a misplaced key. It lets you change the working key without automatically replacing the whole lock. Whether a particular lock can be rekeyed depends on its design and condition.

How to Rekey Locks: What Happens During the Service
The exact work depends on the lock, but the goal is straightforward: make a compatible existing lock work with a new key. For many common cylinder locks, that involves changing the cylinder’s internal keying rather than replacing the entire lock.
A locksmith first needs to identify the lock and check its condition. These are the general steps involved:
- 1. Identify the lock — The locksmith checks the lock type and whether its cylinder is suitable for rekeying.
- 2. Adjust the cylinder — For a compatible lock, the internal keying is changed to match a new key.
- 3. Test the new key — The rekeyed lock is checked with the new key to confirm that it operates as intended.
- 4. Review the keys you need — Tell the locksmith how many locks you want rekeyed and which doors should use the new key.
When Should You Rekey Instead of Replace a Lock?
Rekeying is worth considering when the lock itself is in usable condition but you want to change which key opens it. For example, after moving into a home, you may not know how many copies of the previous key are still in circulation. A new key can reset access for a compatible lock.
It can also suit a household or business that wants to update access after a key is lost or a person no longer needs entry. If you have several doors, explain which ones should share a key and which should remain separate. That helps the locksmith understand the arrangement you want.
A lock change may make more sense when the lock is damaged, worn, or not compatible with rekeying. Rekeying changes the keying inside a lock; it does not repair broken hardware or replace the lock itself.
Can Every Lock Be Rekeyed?
No. Some locks are not designed to be rekeyed, and a damaged or worn cylinder may not be a suitable candidate. The lock’s design and condition determine whether rekeying is practical; if it is not, replacing the lock may be the next option.
People sometimes ask, “What locks can locksmiths not open?” Opening a lock and rekeying it are different jobs. A lock that cannot be rekeyed may still be openable, while a damaged or unusual lock may need a closer assessment before a locksmith can advise what work is appropriate.
If you are unsure what type of lock you have, describe it when you call or arrange for a locksmith to assess it. You can also reach a locksmith in Wichita to discuss the lock and the access change you need.
What Does It Cost to Rekey a Lock?
Lock rekeying starts from $65 per lock. We tell you the price before any work starts, so you can review the quote before deciding how to proceed.
If you are searching for a rekey locksmith cost, check whether the quoted amount is for each lock. Someone comparing rekey cost from a locksmith should also describe how many locks need service and whether they want the same new key to work across them.
A locksmith’s cost to rekey depends on the specific lock and the work needed, so share the lock details when you call. Ask for the locksmith rekey price before work begins, and make sure you understand which locks are included in the quote.
What to Prepare Before You Arrange Rekeying
Make a list of the doors or locks you want changed and note which ones you would like to operate with the same key. If you have keys for the locks, keep them nearby so you can explain what currently works. You do not need to know the lock’s technical name to ask for help.
Tell the locksmith if a lock sticks, feels loose, or has other visible damage. That information can help determine whether rekeying is suitable or whether the lock needs a different solution. If the lock is at a home or business, arrange access to the doors you want assessed.

Frequently asked questions
Do I need to rekey every lock in my home?
No. You can ask about rekeying only the locks you want to include. If you want several locks to use the same new key, tell the locksmith which doors should be keyed alike so the locks can be assessed together.
Will my old key still work after rekeying?
A successfully rekeyed lock is set to work with the new key rather than the previous one. If you have several locks, make sure you know which ones were included so you do not assume an unchanged lock has also been rekeyed.
Can a locksmith rekey a lock if I have lost the key?
Possibly, depending on the lock’s design and condition. Tell the locksmith that the key is missing and describe the lock; they can assess whether rekeying or another option is suitable.
What information should I give when calling about rekeying in Wichita?
Share the type of property, how many locks you want addressed, and whether you want them to use the same new key. Mention any lock that is damaged or difficult to operate so the locksmith knows what to assess.
