The Schlage electronic keypad locks and deadbolts from Ingersoll Rand remain locked until a user enters a valid four-digit access code. The 11-button keypad is designed with large print numbers and blue LEDs illuminate the keypad for enhanced visibility. It has the ability to store up to 17 additional four-digit user codes and users can add, delete or disable access codes in seconds. A 9-volt battery with an average three-year lifespan powers the Schlage. The locks and deadbolts come in two designs, both with knob and lever options, and is offered in eight finishes including satin nickel, satin chrome, lifetime brass and aged bronze.
