Can You Rekey a Smart Lock? 

It depends on the type of smart lock you have. Some smart locks like the August Smart Lock Pro come with a detachable faceplate that allows you to quickly and easily replace the cylinder without having to replace the entire lock.

However, other smart locks like the Schlage Connect are not designed to be taken apart and require the entire lock to be replaced if you want to change the keys. 

The next step is to contact the manufacturer or check their website if you have questions about rekeying your smart lock.

It should be possible for them to tell you whether or not your particular model can be rekeyed. Alternatively, you can follow this article and find the rekeying method that suits your smart lock type.

In short, smart locks offer a lot of advantages over traditional keyed locks but one potential disadvantage is that they can’t be easily rekeyed like their older counterparts. So, what does that mean for you if you want to change your locks? Let’s take a look. 

What are the types of smart locks: How do you rekey each one?

An electronic locking mechanism replaces a traditional keyed cylinder in a smart lock. Smart locks can be opened using a smartphone, fingerprint, key fob, or in some cases, even voice commands.

Most smart locks also allow you to track who enters and exits your home, as well as set up entrance schedules and geofencing features. 

The market today offers a wide range of smart locks on the market, each with its specific features and benefits. Smart locks come in a variety of types, including:

1. Bluetooth-enabled smart locks

These locks use Bluetooth technology to communicate with your smartphone or another compatible device. Here’s how to rekey it:

Step 1: If you’re using a Bluetooth-enabled lock, the first step is to make sure that your lock is properly paired with your device. To do this, consult your lock’s instructions to find the correct pairing procedure.

Step 2: Once your lock is paired with your device, you’ll need to download a rekeying app. There are a few different options available, but we recommend the Kwikset Kevo app for iOS or Android.

Step 3: Open the app and follow the on-screen instructions to create an account. As soon as you’ve created an account, you’ll be able to log in and access your locks from anywhere.

Step 4: Now that you’re logged in, you’ll need to find the “Rekey” option within the app. This may be located in a menu, or it may be a button on the main screen. When you’ve found it, tap it to begin the rekeying process.

Step 5: The app will walk you through the rest of the process, which includes placing your old key into the lock and following the on-screen instructions. Once you’ve completed the process, your lock will be successfully rekeyed!

2. Keyless entry smart locks

These locks do not require a key to be used, making them more convenient and secure. You can rekey them by following the process:

Step 1: Remove the battery cover

The first step is to remove the battery cover from the back of the lock.

Step 2: Remove the batteries

Once the cover is off, you will need to remove the batteries. Some locks may have a release tab that needs to be pressed to take out the batteries.

Step 3: Locate the reset hole

On the back of the lock, there is a small hole that is used for resetting the lock. The paperclip or something similar needs to be inserted into this hole.

Step 4: Press and hold the reset button

With the paperclip still inserted, you will need to press and hold the reset button for about 10 seconds. This will reset the lock and you should now be able to use it without a key.

3. Fingerprint smart locks

The locks, as their name suggests, are fingerprint-activated, ensuring that only you have access to your home or office. You can rekey them if necessary but the process is a little bit more complicated than a normal lock. Let’s see how you can rekey them:

Step 1: Start by removing the screws that hold the backplate in place.

Step 2: With the backplate removed, you should see a small metal rod sticking out from the bottom of the lock. This is the locking mechanism.

Step 3: Using a small screwdriver or a similar tool, gently push on the locking mechanism until it pops out of the lock.

Step 4: Once the locking mechanism is removed, the last step is to remove the old key from the lock. To do this, simply insert a small screwdriver or similar tool into the hole where the key was and twist until the key pops out.

Step 5: With the old key removed, you can now insert your newly made key into the lock and reattach the backplate. Make sure to screw it in place tightly so that the lock is secure.

Step 6: Now your lock is ready to go with your upgraded key!

4. RFID Smart locks

RFID locks use radio frequency identification technology to identify the user and grant or deny access. Here’s how to rekey them:

Step 1: Locate the control panel for your lock. This is usually located near the keypad, and it will have a small slot for a key or other tool.

Step 2: Find the rekeying tool that came with your lock. It will be long and thin, and it will have a small button or switch on one end.

Step 3: Insert the rekeying tool into the slot on the control panel.

Step 4: Press and hold the button or switch on the rekeying tool.

Step 5: Enter your updated code into the keypad.

Step 6: Release the button or switch on the rekeying tool.

Step 7: Test your updated code to make sure it works.

Step 8: Repeat steps 3-7 for each additional lock that you want to rekey.

Pro Tip: RFID smart locks are a superior option for security since they’re more difficult to pick than traditional locks. They’re also convenient since you don’t have to carry around a key. However, if you lose the rekeying tool, it can be difficult to reset the lock. Make sure you keep it in a safe place!
