How to Rekey a Car Lock

If it's the first time you're considering rekeying a car lock, you may be wondering how it's done. Rekeying a lock involves changing the internal configuration of the lock so that the old key cannot be used to operate the lock. When you rekey a lock, you simply keep the old lock, but the old key will no longer operate it. There are many situations where you'll want to rekey a car lock, such as when you lose your car keys or when your locks are compromised. 

Let’s look at the process of rekeying a car lock.

Step 1: Evaluate The Car Lock

Before you start the process of rekeying your car lock, you’ll need to evaluate certain aspects of your vehicle. Find out the type of internal components your lock uses, the complexity of your car lock, and how much time it will take to complete the process.

Step 2: Extract The Lock and Tumbler

The second step is to remove the car lock and take out the tumbler. You’ll notice that the tumbler is set in a way that the existing key can be used to operate the car lock. To change the lock’s configuration, readjust the tumbler so that a new key will be used to operate the lock. This is one of the most time-consuming steps, but with the right tools and experience, you’ll be able to get it done.

Step 3: Mark Your Key Blank for Cutting

Insert a blank key into the tumbler device and mark the positions of each tumbler on the blank key. After marking the blank key, go ahead and cut your new key using a Dremel tool or a set of jeweler’s files. You’ll need to be careful when cutting your new key to avoid cutting the key at the wrong points.

Step 4: Test Your New Key

Once you’ve ensured your new key is cut correctly, reassemble your car lock and test your new key. Your new key should work perfectly if you've rekeyed the lock the right way. If your new key is working correctly, reassemble the entire system, and you'll be good to go.

There you have it. These are the simple steps you’ll need to follow to rekey your car lock. As you can see, rekeying a car lock can be complicated for someone who’s not a knowledgeable and experienced auto locksmith. That’s why this job should be left to a reliable "auto locksmith near me."
