This biometric fingerprint lock is designed to fit standard doors (either left or right handed).  It can be installed either by replacing existing single cylinder deadbolts or in new doors installed in place of single cylinder deadbolts. 

The biometric fingerprint lock can store fingerprints for up to 30 users-4 administrators and 26 users with one fingerprint each.  However, it is recommended to have 1 or 2 administrators and 13 users with a fingerprint stored from each hand. 

The biometric fingerprint lock operates on 4 AA batteries (not included).  Long life batteries will last approximately 1 year under normal conditions (5000 cycles with 1 set of long life batteries under test conditions).  This unit has a low battery indicator to let you know when to change the batteries.  None of the saved fingerprints or settings will be lost during battery replacements. 

In case of emergencies, we have provided 3 overriding keys that let you open the lock like a tradition deadbolt.  The fingerprint scan time is less than 1 second and can recognize and match a stored fingerprint in 2 seconds or less. 

The unit is rated to work in a temperature range from 0-131 degrees Fahrenheit and a humidity range of 0-99 percent.  The lock measures 6 x 3 3/8  x 1 3/4 inches. 

Available in Antique Brass or Nickel Plated.
