In this quick guide, we’ll walk you through the process, when it’s safe to do it yourself, and when calling a pro might be the better option. At Sure Lock & Key, we’re here to make sure you stay safe and secure with the right tools, tips, and trusted residential locksmith services.

Top Reasons to Rekey Your Kwikset Smart Lock

For many homeowners, rekeying is an easy and practical solution to a common concern: control. With Kwikset SmartKey technology, it’s possible to rekey your lock in minutes using the Kwikset SmartKey tool — no need to replace the entire lock. Here are the most common reasons why people choose to do it:

1. You Moved Into a New Home

You can’t be sure how many spare keys are out there from previous owners, contractors, or realtors. Rekeying gives you full control from day one.

2. You Lost Your Keys

If your key is missing, there’s always a chance someone else has it. Rekeying ensures your home stays secure without needing a new lock.

3. Someone Moved Out

Roommate moved, or you had a breakup? Rekeying prevents former occupants from using old keys.

4. You Want One Key for All Locks

Tired of juggling multiple keys? If you have other Kwikset smart key deadbolts, you can rekey them to match a single key.

5. It’s Simply Time for an Update

Maybe your keys are worn or you want more secure access control. Rekeying is a small change that brings peace of mind.

Tools You’ll Need to Rekey a Kwikset Smart Lock

Before diving into the steps, gather the essentials:

Your current working key
The Kwikset SmartKey tool
A new key you want to use
Optional: Kwikset SmartKey rekey kit (if you’re starting from scratch or lost the original tool)

Note: You won’t be able to rekey a smart lock without the original key unless you disassemble the lock entirely or contact a professional. Also, keep in mind that not all Kwikset locks support SmartKey technology. If you find that your lock isn’t compatible or you’re planning to replace it altogether, follow our step-by-step guide on how to remove a Kwikset deadbolt lock to do it safely and correctly.

5 Steps: How to Rekey a Kwikset Smart Lock

Step 1: Prepare the Lock

Make sure the door is open and the lock is in the unlocked position. If you’re working with a deadbolt, keep the thumb turn in a vertical position.

Step 2: Insert the Existing Key

Place your current key in the lock and turn it 90 degrees clockwise. This step prepares the lock to enter rekeying mode.

Step 3: Use the SmartKey Tool

Insert the Kwikset smart key tool (a small pin-like tool) into the tiny hole next to the key slot. You should feel a slight click. Remove the SmartKey tool, but keep the key in place.

Step 4: Insert the New Key

Without turning, remove the old key and insert your new key into the slot. Now turn it 180 degrees counterclockwise, then return it to its original position. This completes the Kwikset smart key installation.

Step 5: Test the Lock

Remove the new key, then reinsert and turn it again to confirm it works. Your old key should no longer operate the lock. If you face issues, don’t force the key — this may damage the lock cylinder.

Mistakes to Avoid When Rekeying Smart Locks

Using a worn-out or damaged key
Inserting the SmartKey tool too forcefully
Turning the key in the wrong direction
Trying to use the Kwikset rekey kit on a non-SmartKey lock
Not checking if the lock is compatible with SmartKey technology
