Section 1: Overview of the Kwikset 660 Deadbolt

Disassembling the Kwikset Lock

To begin the rekeying process, you will need to disassemble the lock. Start by loosening the two screws that hold the lock in place. You can leave the bolt in the door as you remove the cylinder by carefully sliding it out. The cylinder is secured with a small C-clip, which can be easily dislodged with the help of a pick tool.

Identifying the Keyway and Tailpiece

Once you have removed the cylinder, it’s time to identify the keyway and tailpiece. In this case, we will be using the Kwikset KW1 key. The rekeying process becomes straightforward if you have the appropriate key. Simply insert the key at a 30-degree angle and push the follower through, revealing the lock’s five pin combination.

Understanding the Lock Parts

Before we dive into rekeying, it’s important to familiarize ourselves with the various parts of the lock. The top part, where the springs are located, is called the Bible. The central component is the plug, and the keyway or profile helps guide the key. Lastly, we have the Kwikset KW1 key, which is specific to this lock.

Rekeying Lock

Using the lab kit, we can now proceed to rekey the lock. Start by inserting the top pins back into their respective chambers. By working from the middle of the lock, you can easily place the pins back into position. Ensure that you hold the pins with tweezers and push them in until they are flush with the plug.

Adding the Bottom Pins and Springs

With the top pins securely in place, it’s time to install the bottom pins. These pins have a flat side that contacts the driver and a rounded side that enables smooth key insertion. Place the rounded side of the bottom pins facing downward and carefully insert them into their designated chambers. Don’t forget to add the springs as well.

Verifying the Rekeying

Before reassembling the lock, it’s essential to double-check the keying. In our case, we used a factory key, but you can also cut the keys by code. By using a Pro Lok tool, you can determine the cuts required for each pin. Verify that the pins match the desired combination and ensure that they are not sticking out too far.

Final Kwikset Assembly

Now that the rekeying process is complete, it’s time to put the lock back together. Begin by placing the key in the plug and aligning it at a 45-degree angle. Insert the plug into the cylinder and ensure it is securely in place. Avoid pulling the key out abruptly to prevent dislodging any components.

Installing the Deadbolt Tailpiece

To complete the rekeying process, install the deadbolt tailpiece. Make sure to reattach any clips or accessories that were removed during disassembly. It is advisable to replace these components if they show signs of wear or damage. Reinstall the lock in its original position and test the key to ensure a successful rekeying.

Conclusion

Rekeying the Kwikset 660 deadbolt lock is a straightforward process that can be done with a few simple tools and a bit of practice. By following the steps outlined in this blog post, you can confidently rekey these popular locks and ensure the security of your home or business.
