Setup Instructions: Setting Your Password

Your KENRONE U Lock comes with a default combination, usually "0000". Follow these steps to set your personalized 4-digit combination:

2. Open Dust Cover: Slide the release button to open the dust cover, revealing the combination dials and the password reset switch.
3. Locate Reset Switch: Find the combination adjuster (password reset switch) at the bottom of the lock body.
4. Engage Reset Mode: Dial the code switch from position A to position B. This puts the lock into password setting mode.
5. Set New Password: Rotate the combination dials to your desired new 4-digit password. Choose a memorable combination.
6. Confirm New Password: After setting your new password, dial the reset switch back to its original position (from B to A). This saves your new combination.
7. Test New Password: Scramble the dials and then enter your new combination to ensure it unlocks the device correctly.
