IULOCK support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I factory reset my IULOCK?

    Remove the interior cover screws, locate the reset button on the battery pack, then press and hold it for 7 seconds until you hear a long beep. The master passcode will return to the default '123456'.

  • Do I need to reactivate the remote code function after a reset?

    Yes, for safety reasons the remote code function is disabled by default. It must be reactivated on the web portal after the lock is reset or repowered.

  • How many user codes can I program into my IULOCK?

    Up to 50 possible user codes (1-15 digits long) can be stored in the lock at one time. You also have 1 master code that can be modified but cannot be deleted.

  • What is the IULOCK Passcode Disguise feature?

    This built-in feature protects your codes from prying eyes. Regardless of how many random extra digits are entered before or after your actual passcode sequence, the lock will still open.

  • Where do I generate remote codes?

    You can generate remote access codes by visiting mylock.iulock.com, registering an account, and adding your lock. These codes let you authorize guests without the lock needing its own Wi-Fi connection.
