Replace your doorknob with a maintenance-free keyless door lock, and you'll never have to worry about remembering your keys again. The Heavy-Duty Digital Lever has a magnetic latchbolt that locks automatically when you close your door, functioning as a standard door latch but with deadbolt-quality security. Since it requires no electricity or batteries, you'll have peace of mind, knowing that this security device will always work: Just enter your user-defined 3- to 7-digit code to release the latch. Adding style to function, this heavy-duty keyless door lock has an elegant, attractive lever handle instead of a standard doorknob. For Use on Right-Hand Doors This digital door lock is made for right-hand doors. If you have a left-hand door, buy the left-hand version instead. To determine if you need a left-hand or right-hand lock, stand facing on the exterior side of your door. If the hinges are on the left, it is a left-hand door requiring a left-hand lock. If the hinges are on the right, it is a right-hand door requiring a right-hand lock. Additional Finishes Available The Heavy-Duty Digital Lever door lock is also available in chrome and antique brass finishes.
