"Keys" Go ahead and leave home without them!

The ultimate in keyless entry.
The Fingerprint ID Door Lock / Deadbolt is a cylindrical lock combined with a security deadbolt that will let you enter the house using just your finger. It reads your unique fingerprint and allows only the prints that have been programmed in. Six AA batteries are required and are sold separately.
The Fingerprint ID Door Lock / Deadbolt will accept up to 50 fingerprints in its system, providing keyless access to your entire family or your small business. This lockset is designed to fit any standard wooden door that has installation holes for a mechanical cylindrical door lock. It can directly replace standard locks, no additional hardware is required. Programming is easy, and the LED display provides added convenience for programming. Four keys are included for manually unlocking the door.
Low Battery Warning
If the batteries are low, you will hear four beeps when the lock is used. Replace the batteries as soon as possible; the Fingerprint ID Door Lock / Deadbolt's non-volatile memory will retain all enrolled fingerprints and other setup functions.
