The battery(s) in my lock run out really fast.
This could be an indication that the lock has an electronic short. There could damage to the lock’s ribbon cable during installation. There could be a problem with the keypad.
Inspect the ribbon cable. If there are any hard bends or crimping please straighten them out and operate as normal to see if the issue has been corrected. Please contact you safe company/lock smith/distributor for warranty. NOTE: If the ribbon cable has been damaged beyond repair, the lock will have to be replaced.
