Are you still hiding keys under your doormat or in a planter for houseguests and service people? Don't risk your home's security by leaving random keys out for anyone to find. The Touchpad Lockset allows you to lock and unlock your door using any security code you choose. You'll be able to leave your house with confidence, even if you're in the habit of losing or forgetting your keys. The unit uses 4 AA batteries (sold separately). Programming security codes is easy. Choose any code from two to eight digits. The Touchpad Lockset will accept up to six different combinations, and each code can be added or deleted individually, which is convenient if a service provider needs to gain access only for one day or if you have a houseguest for a week. Should anyone try to break in by testing possible combinations, a warning alarm will sound after four failed attempts. The antique brass finish comes with a lifetime tarnish-free guarantee. Additional features include a glow-in-the-dark 12-key keypad. This keypad lock is made for left-hand doors. If you have a right-hand door, buy the right-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. The Touchpad Lockset is also available in antique brass, brass, and nickel.
