How to Rekey a Kwikset Door Knob: A Comprehensive Guide

Understanding how to rekey a Kwikset door knob can be a valuable skill, enhancing both your convenience and security. Whether you need to match an existing Kwikset lock or simply seek to expand your key access, this guide is designed to simplify the process of rekeying your Kwikset door knob. We will cover everything from sourcing the necessary tools to completing the rekeying process, ensuring that you can handle the task confidently.

Step 1: Removing the Kwikset Cylinder

To rekey your Kwikset door knob, the first step is to remove the cylinder. This is where the Kwikset EZ Key system and the specialized Kwikset Cylinder Removal Tool come in handy. Although you can use a Phillips screwdriver and a flat screwdriver, the Kwikset tool is significantly more efficient and less likely to damage the lock. The tool is designed to fit the unique design of the Kwikset door knob, saving you time and effort.

Before you start, ensure you have the actuator bar removed from the center of the curved bar by pressing the tab at the bottom of the curved bar. Then, use the cylinder removal tool to reach into the hole where the actuator bar was and squeeze the two prongs in the back of the cylinder. This simple maneuver will remove the cylinder from the door knob. If you lack the tool, a combination of a Phillips screwdriver and a flat screwdriver can work, but it's much more challenging and requires precise technique.

Step 2: Rekeying the Cylinder

Once you have the cylinder out, you can rekey it just like any other cylinder. To rekey it to match another existing Kwikset lock cylinder, bring the key for that lock along with the door knob to a home center that carries Kwikset products. The trained staff there can swap out the pins for you, saving you time and ensuring the lock functions correctly.

Step 3: Replacing the Existing Key with a New One

To rekey the cylinder itself, find or make another Kwikset key that you want to use. Remove the clip in the back of the cylinder that holds the core in. Use the existing key to unlock the cylinder and turn it 90 degrees, then use a following bar to push it out from the back. Remove the existing key and replace it with the new one.

Replace the tumblers in the cylinder so that the top of the new tumblers is even with the top of the core. If necessary, file the last bit to ensure they align perfectly. Insert the core back into the cylinder by using it to push the following bar out, then reattach the clip at the back of the cylinder.

Final Steps and Tips

After completing the rekeying process, it's a good idea to test the lock thoroughly. Make sure that there is no gap between the core and the following bar or the top pins may fall into the gap, requiring you to repack all the top pins and springs into the cylinder. Following these steps carefully will help you successfully rekey your Kwikset door knob and ensure it remains watertight.

Conclusion

Rekeying a Kwikset door knob is a straightforward task that can be done with the right tools and a bit of patience. Whether you are a homeowner looking to maintain security or a locksmith adjusting locks, this guide will help you navigate the process of rekeying a Kwikset door knob. By following these detailed steps, you can ensure that your lock remains functioning and secure, adding an extra layer of protection to your home or business.
