Honeywell electronic digital deadbolts unlock with a programmable 4 to 8 digit user code (keyless entry) and feature traditional key access as well. (50) Different user codes can be programmed and deleted as desired for service personnel, office staff or guests. A backlit keypad illuminates the push buttons for easy viewing late at night or in a dark hallway. The Honeywell electronic deadbolt allows you to set an automatic lock function that will return the deadbolt to the locked position at a programmed amount of time after the lock is opened. The vacation mode puts the system into a low power consumption state and disables all buttons and functions until the programmer chooses to reactivate the lock. With the Honeywell electronic digital deadbolt you never have to fumble with keys for a door again.
