This is a very good Biometric Electronic Lock. I dont understand the only 2 other reviews; they may have had issues, but it wasn't the locks fault. Mine worked fine right out of the box😊. Before I installed it I watched the YouTube videos and read the instructions. No issues, and no problems. This lock allows you to either use a code or your fingerprint(s)!
Then, if you happen to screw that up later in life, hopefully you reset the reset code as suggested in the very beginning, so only you ( the safe owner) can get that code back from the folks at Liberty, to be able to reset it back to factory, and start all over. Its like having a safe for your safe lock😉
