Things to keep in mind when you change the user access code on Your Kwikset SmartCode 909

  • Make sure you don’t use the previous codes that have already been set for your deadlock previously.
  • Don’t pause for more than 5 seconds, this will time out the programming process and you will have to start from the beginning.
  • If you can’t remember the code position, factory reset the SmartCode 909 to remove all the previous codes first and then go for the new code.

Factory Reset SmartCode 909

Before you start factory resetting your Kwikset SmartCode 909, you must know that this will erase all the previous users and you will have to program it from scratch, the same as you did when you installed it for the first time.

To reset the Kwikset Smartcode 909, follow the below steps:

  1. Take out the cover from the device and remove the battery.
  2. Now, put the battery pack inside while holding the Program button.
  3. Keep holding the button for 30 seconds or until you hear a beep sound from the lock and see a red flash on the lock.
  4. Now, click on the Program button and if you see the lock flashes green light and beep once, the reset is successful.
  5. If your lock doesn’t flash green light, start from the 1st step again.

Now, you can add new user codes to your SmartCode.

But before this, you will have to complete the door handing identification process. This process lets your lock understand whether you are a right-handed or left-handed person.

Here’s how you can perform the door handing identification process:

  • Take out the battery from the door lock and press and hold the program button.
  • Insert the battery pack inside the lock while holding the program button.
  • Keep holding the program button until you see the lock latch moves on its own.

Now, you can add user codes to your SmartCode 909.

How To Delete/Disable User Code

To remove a User Code on your Kwikset SmartCode 909, simply replace it with a new User Code in the spot of the User Code you wish to delete.

The new code will take precedence over the old one.

And if you can’t remember the position of the code you want to remove, reset your lock and add new ones as we’ve shown above.

How To Enable Master Code on Kwikset SmartLock 909?

You must be thinking why should you enable master code if you already have a user code set up on the Kwikset SmartCode 909?

Master code is provided to keep your smart lock safe and more secure. When you set up your Master code to your lock, your lock asks you to enter the master code whenever you want to do any programming changes. This also prevents any unauthorised changes made by any other user.

You can follow the below steps to enable master lock on your Kwikset SmartCode 909:

  1. Keep your door open while enabling the master lock.
  2. Press and hold the Program button for 5 seconds until you see your keypad flashes green.
  3. Now, enter the master code for your device and press the “Lock” button available on the device.
  4. Your lock will beep and flash green indicating that your master code is set.

If you hear three beeps, three red flashes, and then one long beep, the programming has failed. Start from the first step again.

Deleting or Disabling Master Code

If you want all your family members to have the authorization to enable or disable the user codes, you should delete or disable the master code. However, I won’t recommend disabling the master code unless you really need to do.

To do this, you can follow the below steps:

  • Press and hold the Program button on the keypad for approximately 5 seconds, or until the keypad’s light turns green.
  • To disable the Master Code, press the Lock button on the keypad and enter the current code.
  • To change your Master Code, enter the current code and then press the Lock button again.
  • The lock will flash green and make a beeping sound once to indicate that the Master Code has been disabled.

Now that you have disabled the master lock, anyone with the user code can change or add the user codes.
