How Do You Change The 4 Digit Code On A Kwikset Keypad Lock? 10 Best Ways

1. Using the SmartCode Button – Best for Quick Resets

The SmartCode button is the simplest and fastest way to change your 4-digit code on most Kwikset keypad locks. Start by removing the back cover and locating the small “Program” button inside the housing. Press and hold it until you hear a single beep or the keypad flashes red, signaling readiness to enter a new code.

Next, enter your new 4-digit code directly on the keypad, then press the lock button to confirm. The lock should flash green or beep twice, confirming successful programming. This method works perfectly for SmartCode 909, 910, 913, and 915 models.

It’s ideal for homeowners who prefer manual setup without a smartphone app or network pairing. Using the SmartCode button ensures your security code remains private and can be changed anytime. This approach also helps if your lock has been recently factory reset.

To use it, insert your current working key and turn it 90 degrees clockwise, then use the SmartKey tool in the small hole next to the keyway. Remove the tool, pull out the key, and insert your new one to complete the re-keying process.

After re-keying, it’s wise to also update your 4-digit code for digital consistency. Press the Program button and follow the same steps as before to enter a new code. This approach synchronizes your mechanical and electronic security systems.

The Smart Re-Key feature is excellent for people who recently moved homes or lost spare keys. It eliminates the need for professional re-keying services while maintaining complete control over who can unlock your door. It’s one of the best dual security upgrades for Kwikset owners.
