how to rekey kwikset smart lock

To rekey a Kwikset SmartKey deadbolt or smart lock, you normally use the existing working key plus the small SmartKey tool to put the lock into “re- key” mode, then sync it to a new key in a few simple steps.

Before you start

  • Ensure the door is open and can’t accidentally close while you’re working (you don’t want to lock yourself out).
  • Confirm your lock is a Kwikset SmartKey style: there will be a small, narrow hole next to the keyway for the SmartKey tool.
  • You must have:
    • Current working key for that lock.
* The Kwikset SmartKey / reset tool (often included with the lock or in a rekey kit).

* The new key you want the lock to use.

If you do not have a working key, rekeying typically requires disassembling the cylinder or having a locksmith cut a key to the lock first; this isn’t considered a simple DIY step for most people.

Basic 3-step SmartKey rekey process

This is the standard Kwikset SmartKey Security procedure; always double‑check your specific model’s manual, but the flow is usually the same.

  1. Use the current key
    • Insert the key that currently operates the lock.
 * Turn it 90° clockwise (usually from vertical to horizontal).
  1. Use the SmartKey tool
    • With the key still turned, insert the SmartKey tool fully into the small SmartKey hole until you feel or hear a click.
 * Remove the SmartKey tool, then pull out the current key without turning it further.

 * The lock is now in “learn” mode for the new key.
  1. Program the new key
    • Insert the new key all the way in; make sure it is fully seated to the shoulder/indent on the cylinder face.
 * Turn the new key 180° (often counterclockwise) and then back as directed:
   * Many official instructions say: rotate 180° counterclockwise, then 180° clockwise, then 90° back to the starting position.

   * Some DIY guides simplify it as: turn to the opposite side, then back to the original position.

 * Return the key to the original vertical position and remove it.

Your lock should now be keyed to the new key, and the old key should no longer operate it.

Safety and troubleshooting tips

  • Test with the door open :
    • With the door open, lock and unlock several times using the new key to be sure it turns smoothly and doesn’t stick.
* Confirm the old key no longer turns the cylinder.
  • If the new key won’t turn or feels rough :
    • Don’t force it; forcing can damage the SmartKey mechanism.
* Repeat the rekey steps carefully, ensuring:
  * The original key was turned 90° before inserting the tool.

  * The SmartKey tool was inserted fully until it clicked.

  * The new key was fully inserted during programming.
  • If you lost the original key or a rekey attempt failed :
    • Some locksmith tutorials show complete cylinder disassembly to reset without the original key, but this is advanced and easy to get wrong.
* Most manufacturers and locksmiths recommend taking the lock to a professional in this situation to avoid permanently damaging the cylinder.

Smart lock vs. basic SmartKey notes

  • On electronic Kwikset smart locks (Halo, SmartCode, etc.), the mechanical keyway rekeys exactly like a normal SmartKey deadbolt using the same 3-step process.
  • Rekeying the physical key does not change your keypad entry codes; those are reset or changed separately in the lock’s programming menu or app.
