Biometric lock is easily programmed by scanning the unique lines of your fingerprint. Unable to Duplicate - Unlike a key, a fingerprint cannot be lost, stolen, or taken to a locksmith for duplication. Biometric locks detect whether a thumbprint is a match without having to send information to an external source. Using special silicone sensors, these locks will reject anything that doesn't resemble the characteristics of a human finger. Can be secured in glove box, under seat, in center console etc.
