If you’re looking to improve the security of your home or simply want to update your current entry code, changing the code on your Kwikset lock is a wise decision. Whether you own the traditional SmartCode model or the more recent Halo and Aura smart locks, this easy-to-follow guide will give you step-by-step instructions to reset or reprogram your Kwikset lock code. Mastering this process gives you control over who has access and provides peace of mind.

TLDR (Too long, didn’t read):

Changing your Kwikset lock code involves opening the battery cover, entering programming mode, and setting a new user code. The process varies slightly depending on your model (SmartCode, Halo, or Aura). Make sure to follow each step carefully to ensure the new code works properly. If you’re unsure which model you own, check the user manual or product label inside the battery compartment.

Step 1: Identify Your Kwikset Lock Model

The first step in updating your lock code is identifying the specific Kwikset model you own. Models such as the SmartCode 909/910 series and smart locks like Halo and Aura each have slightly different procedures.

  • SmartCode Series: These models use a physical keypad and require direct interaction with the programming button on the back panel.
  • Kwikset Halo: WiFi-enabled and controlled via the Kwikset app, allowing for remote programming.
  • Kwikset Aura: Bluetooth-enabled and also uses the Kwikset app for changes.

For this guide, we’ll cover instructions for both standard keypad models like SmartCode and smart models like Halo and Aura.

Step 2: Remove the Interior Cover

To access the programming button or reset functionalities, you need to remove the interior cover of your lock. This is typically where the battery pack is also housed.

  1. Locate the interior side of your door lock.
  2. Gently remove the battery cover by sliding it upward or unscrewing it (depending on the model).
  3. Set the cover and any screws aside safely.

Step 3: Access or Enter Programming Mode

The method of entering programming mode differs slightly depending on whether you have a keypad lock or a smart lock:

For SmartCode Models:

  1. Press and hold the Program button on the interior unit until the keypad flashes green and you hear three beeps.
  2. Release the program button—your lock is now in programming mode.

For Halo or Aura (Using Kwikset App):

  1. Open the Kwikset App on your smartphone.
  2. Select your device from the dashboard.
  3. Tap “Users”, then select “Add User” or choose an existing user to update the code.

Step 4: Add or Change a User Code

For SmartCode Models (Manual Entry):

Follow these steps carefully:

  1. Enter a new code (between 4–8 digits) on the keypad.
  2. Press the Lock button once. If successful, you’ll see a flashing green light, and the lock will beep once.
  3. Repeat the process for each additional code you wish to enter (up to 8 user codes).

For Halo or Aura (via App):

Changing the code is convenient and remote through the app interface:

  1. After selecting a user in the app, enter a new access code (4–8 digits).
  2. Tap “Save” to sync the new code to the lock via Bluetooth or WiFi.

Tip: Always test the new code while the door is open to prevent accidental lockouts.

Step 5: Delete an Old Code (If Needed)

You may also want to remove outdated or unused codes. Here’s how:

Manual Method (SmartCode):

  1. Re-enter programming mode by pressing the Program button.
  2. Enter the old code you wish to remove.
  3. Press the Lock button.
  4. If successful, you’ll hear one long beep and see a red LED flash.

Kwikset App Method (Halo or Aura):

  1. Go to the app’s “Users” section and select the user whose code you want to delete.
  2. Choose “Delete User” or “Remove Access Code”.
  3. The change will update to the lock automatically.

Step 6: Perform a Factory Reset (Optional)

If you’re troubleshooting or moving into a new home, a factory reset ensures no lingering user codes remain.

  1. Remove the interior cover and the battery pack.
  2. Press and hold the Program button.
  3. While still holding the button, reinsert the batteries.
  4. Continue to hold the button for 30 seconds until the lock beeps and the LED flashes red.
  5. Release the button. The lock is now reset and ready for new code setup.

Tips for Better Security and Usability

  • Avoid common numbers: Don’t use simple combinations like “1234” or birthdays.
  • Change codes regularly: Especially when giving access to temporary visitors or service workers.
  • Use distinct user codes: Assign unique codes to family members or guests for easy tracking.
  • Enable auto-lock: Most Kwikset smart models allow you to set the door to auto-lock after a set period for added security.

Common Troubleshooting Issues

If for some reason your new code doesn’t work or you encounter programming errors, refer to these solutions:

  • Beeping with red LED: The code you entered already exists or violates the minimum digit requirement.
  • No response after entering a code: Batteries may be dead or the lock is misaligned. Try resetting or replacing batteries.
  • Can’t program via app: Ensure Bluetooth or WiFi is enabled, and your app is connected properly to the device.

Final Thoughts

Updating or changing your Kwikset lock code might seem technical at first, but once you’ve done it once, it becomes a quick and empowering routine. Whether you’re ensuring your home security after a roommate moves out or simply staying up to date with access control, knowing how to modify your lock settings is essential.

Remember to keep your lock’s model number and Kwikset user manual handy for future reference. With modern smart locks offering seamless programming through your smartphone, there’s really no excuse not to manage your home security like a pro!

Now that you know how to change Kwikset lock codes easily, go ahead and secure your space with just a few thoughtful steps. Your future self—and your peace of mind—will thank you.
