Troubleshooting

• I cannot insert the spindle into the latch hole, because of the 2 sides of the spindle hole of the latch are not aligned?
  • Let the hole parts move a few times in the 2-3/8 and 2-3/4 positions and the spindle holes of the latch will automatically align.
• Why is it beeping after keypad light off?
  • The battery may be low. Please replace the battery.
• The lock doesn’t work?
  • Try replacing the battery or using the backup battery. If the lock still does not work, contact customer support.
• Why can’t I open the door?
  • You may be waiting too long to open the door. After entering a code, turn the handle to open the door while the lock LED indicator light is green.
  • Once the LED indicator light is off, the lock will return to locked position immediately.
• Why I can open without passcode?
  • You maybe active the passage mode, use master code access will turn off this function.
  • If you just installed it, make sure the “THIS SIDE UP” on the spindle is facing up (ceiling).
• I forgot all my codes.
  • The lock must undergo a hard reset in order to set the master code back to default and erase all other codes. In order to perform a hard reset,please refer to the above “Restore Factory Settings”.
