This is because of the expense to get a locksmith onsite which takes the form of a trip charge.

Sometimes, but only if you are buying new locks through them (they will rekey them to match one key). A locksmith will rekey locks you bring to the for much less than the cost of a new lock.

The main price differences between having a locksmith out to your home to rekey and bringing the locks to a lock shop occur because:

  • You’ll save the trip charge (the cost associated with getting a locksmith to your location), and
  • The rekey will be a little less expensive, because you will be doing the removal and reinstall of the hardware.

Locksmith Pro Tip: When in doubt, take pictures at each step when removing the lock body from the door – this will help you replace the hardware properly!

Taking your locks into a locksmith shop for rekeying is a great low-cost option available to you if you:

  • Only have one or 2 locks on a single door and

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 $7 additional.

The Cost to Rekey Locks at My 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.

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 our home to perform the key is $75, depending on where you live. The cost to rekey each cylinder will be a little bit more expensive because the locksmith is doing the removal and replacement of the hardware. The cost to rekey a lock will be around $20 per lock cylinder (every keyhole).

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 $7.

High Security Key Blank
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 keyblanks.

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 yourself are available on our website, and we sell Smartkey Rekey Kits available with a change tool and two new keys.

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 Home Locks


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

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 take care of this too. The cost (lock and labor) to rekey/replace mailbox lock is around $40.

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).
