Double Sided Deadbolt = 2 Cylinders

A ‘cylinder’ is where a key goes into a the lock – so each keyhole you have will need to be changed and incur this cost. Some locks have 2 cylinders – a key on each side, and some instead have a thumb turn and only one cylinder. Rekeying is priced by cylinder, and not by locks, so keep this in mind – just count the number of keyholes.

If you don’t have the existing key, the locks can still be rekeyed but it will cost slightly more as it will take longer to perform the rekey. Expect around $8 additional.

Cost Saving When a Locksmith Goes to Your Home

For larger jobs with more doors and cylinders to be changed (or if you just aren’t comfortable or willing to do a little of the work), it will be worth your time and money to hire a locksmith to come out to your location.

If you have a locksmith come out to your home, you start to save money at roughly 4 locks. That is, you will need to have at least 4 locks rekeys before it is cheaper to rekey than to replace. However, you do have the added value of having a local locksmith take care of everything and ensuring everything is functioning properly even if the price is comparable. After 4 locks, it’s less expensive to rekey the home.

A Trip Charge Covers the Cost of Getting a Fully Outfitted Locksmith Van to Your Home

The cost of a trip charge to get a locksmith to your home to perform the rekey will be around $90-125, depending on where you live. The cost to rekey each lock at your location will be about $25 per cylinder, plus the trip charge. It is more expensive to rekey a lock at your location because the locksmith is doing the removal and replacement of the hardware.

Arizona Locksmiths charge 5% less than the national average as our cost of living is lower than many other states.

There are also some circumstances when the costs will be a little higher. For instance, if you don’t have a working key for a door lock, all is not lost – locksmiths can still rekey them, but they will have to pick the lock open in order to pull the cylinder. When you don’t have the current key the cost to rekey the lock will have a surcharge of about $8.

High Security Key Blank

House Rekey Cost Variables

You may also have specialty hardware if you live in an upscale home; things like profile cylinders (which take a longer time to rekey due to how they are built) or some homes have complex 3 – point lock systems that are a bit more time consuming in getting the cylinders out for a rekey.

You may have a high security lock system in place. If you have high-security locks in the home, you will know it. The keys won’t look like any other you have ever had. These lock systems often have more internal moving parts which are retooled in the rekey, and the keys themselves are usually more expensive. These are great for security, but the trade-off is a higher price for the key blanks.

Each of these scenarios will add a moderate cost increase to your rekey, but most homes we go out to have the most common brands (Schlage, Kwikset, Yale, Baldwin are all popular), and these are fairly standard at the basic prices we’ve listed above.


Rekeying a Kwikset Smartkey Lock – Special Case

Kwikset SmartKey Locks Can be Identified by the Extra Hole

One other note – newer Kwikset residential products (and, by licensing agreement, some newer Baldwin products) have a different kind of cylinder system using wafer technology instead of pins, called a ‘SmartKey’. You can recognize this by the addition of a second small hole next to the keyhole.

One of the added benefits to this system is that the home owner can rekey their own Smartkey locks for $0 (so long as you still have the current working key, and a small tool provided by Kwikset).

Instructions for how to rekey SmartKey locks and Smartkey Rekey Kits are available on our website .

However, if you have a Kwikset Smartkey lock without the existing key it is very labor intensive to rekey the lock. It requires a special reset cradle and a lot of time. In some cases, it’s less to just replace this lock if you don’t have the keys. To rekey a Kwikset Smartkey lock rekeyed without the existing key, you can expect to pay about $30.


The Cost to Rekey Other Common Locks Around the Home

Rekeying Padlocks:

ABUS Padlocks Can Work from House Keys

Padlocks by a number of manufacturers like Master Lock, American Lock, and ABUS can also come in rekeyable keyways. If you buy, or have the right product, these can be rekeyed to match your house key. These are great when you don’t want to track additional keys, such as with a side gate or shed.

You can pick up a rekeyable ABUS padlock on Amazon for a great price. Just order the keyway that matches your house key. Take it into you local locksmith shop and they will rekey it to match your house key. Or, even better, support your local locksmith and they will get you all set with a padlock that works with your home key in one stop.

The cost to rekey padlocks is usually the same as any other lock cylinder. Your local locksmith shop can help you get the right padlock or rekey an existing one.

Mailbox Rekey

If You’ve Just Moved In, Have the Mailbox Rekeyed Too

The Cost to Rekey Mailbox Locks:

Many community mailbox banks have locks that are the responsibility of the home owner (you can verify if this is the case with your local post office). These locks typically aren’t made to be rekeyed, but they can be replaced easily enough.

While a locksmith is at your house performing a rekey, have them rekey the mailbox too. The cost (lock and labor) to rekey/replace mailbox lock is around $40. Plus the trip charge if the locksmith is not already out onsite.

For this price the locksmith will drill out the mailbox lock (when you don’t have a key) and replace the lock with a new lock. If you can get the postman to open the box for you, just remove the lock and take it into a local locksmith shop. They will have the replacement lock on hand. It is best to bring them the lock because there are a few types and the locksmith will want to match it.

In some communities, however, there may be proprietary locks which may not be able to be addressed with a locksmith (you would go instead to a home or community association or the post office to address these).
