Cost to Rekey A Home
Just bought a home? Just tossed your roommate? Fired your cleaning crew or no longer need that house sitter? It’s time to rekey your locks! How much is a rekey? This post will give you the information you need to understand the rekeying process, and the costs associated with it.
Most homeowner decide to have locksmith out on site to do the work so that they don’t need to remove and replace the locks themselves.
The cost to rekey a house with 3-doors is from $200-$250. This cost includes a service call and the cost to remove the locks, rekey the lock cylinders, and reinstall. The cost to rekey your house will fluctuate depending on the total number of lock cylinders (i.e. keyholes) that are being rekeyed. Homes location (i.e. city and state) may also impact cost due to cost of living differences.
To reduce the cost of a home rekey, as the table “Cost to Rekey a Home” below shows, you can take the house locks into a local lock shop. This drops the rekey price down to about $13 per lock cylinder (per keyhole). Bringing your locks to a lock shop is the most affordable way to rekey a home.
So bringing those same house locks into a lock shop for rekeying would be just around $78. If you are able, you will save money by taking your locks to a local locksmith shop
The table below provides detailed pricing. We arrived at that price this way. The national average price of a service call is $90-125 and average cost to rekey a lock cylinder is $25 per cylinder (keyhole). The most common number of keyholes in a home is six, as most homes have three doors with each door having two keyholes.

Is it Cheaper to Rekey or Replace Locks?
When you want to protect your home from anyone that may have an existing key copy, you can rekey the locks so that they work with a new key. You DO NOT need to replace the door hardware. But, how much is a rekey? Is it cheaper to buy new home locks?
It is always cheaper to rekey a lock than to replace it. Depending on the door hardware, you can save up to 10X by rekeying the lock rather than buying a new one. The savings can be substantial as the number of locks increases. You will get the biggest savings when you can bring your locks into a locksmith shop near you.
Cost Savings When Locks are Taken to a Locksmith Shop?
When it’s possible, the least expensive rekeying option is to bring the locks into a lock shop.
Will Home Depot rekey locks? 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
- Can have someone who can watch the home while you’re at the locksmiths having the work done and
- Feel comfortable with removing and replacing the hardware yourself.
The cost to rekey a house lock cost about $13 per lock cylinder when brought to a lock shop with the existing key. You save money when brought into a shop because you are providing the labor to remove and replace the lock on the door.
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.
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.
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
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
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.
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).
