To rekey a Kwikset lock, the exact process depends on whether it is a SmartKey lock or a traditional pin-and-tumbler lock.

Rekeying a Kwikset SmartKey Lock

Kwikset SmartKey locks feature a patented rekey technology that allows you to rekey the lock yourself quickly without removing it from the door. The steps are:

1. Make sure the door is open and the lock is in the locked position (deadbolt locked or knob/lever locked).
2. Insert the current key and rotate it 90 degrees clockwise.
3. Insert the SmartKey tool fully and firmly into the SmartKey hole; you may feel a click.
4. Remove the SmartKey tool and then remove the current key.
5. Insert the new key fully into the lock so the edge touches the cylinder face indent.
6. Rotate the new key 180 degrees counter-clockwise, then 180 degrees clockwise.
7. Pull the key to ensure it does not come out, then rotate it 90 degrees counter-clockwise back to the starting position.
8. Remove the new key. The lock is now rekeyed to the new key, and the old key will no longer work

This process is fast, easy, and can be done in seconds with the SmartKey tool provided with the lock.

Rekeying a Kwikset Pin and Tumbler Lock (Non-SmartKey)

For traditional Kwikset pin-and-tumbler locks (without SmartKey):

• You need to remove the lock cylinder from the door.
• Use a Kwikset rekeying kit, which includes a key gauge, plug follower, and new pins.
• Disassemble the cylinder plug, remove the old pins, and insert new pins that match the cuts of the new key.
• Reassemble the lock cylinder and reinstall it on the door.

This process requires more tools and some mechanical skill. It is often done by locksmiths but can be done by homeowners with the proper kit and instructions

Rekeying Kwikset Locks Without a SmartKey Hole

If your Kwikset lock does not have a SmartKey hole, it means it is a traditional pin-and-tumbler lock. You cannot use the SmartKey rekey method. Instead, you must either:

• Remove the lock and take it to a locksmith for rekeying, or
• Re-key it yourself using a Kwikset rekeying kit as described above

In summary, if your Kwikset lock has the SmartKey feature, you can rekey it quickly yourself using the SmartKey tool and a new key. If not, rekeying involves disassembling the lock cylinder and changing the pins, which requires a rekey kit or professional locksmith assistance.
