Replace your door lock with an inexpensive wireless radio frequency (RF) remote electronic digital door lock. Wireless radio frequency (RF) remote keyless door lock is easy to install and even easier to program. If you are replacing an existing typical deadbolt with a 2-1/8 inch mounting hole, it's even easier.
The keyless door lock comes with Anti-Theft Rolling Code Security to ensures that your security can adapt and stay effective 24 hours a day, 7 days a week. Push the remote control and the deadbolt retracts.
Since the keyless door lock is a deadbolt and not a latch, you will need to lock it manually from the outside by pressing a button or from the inside by turning a small turn piece. It can NOT lock automatically like a latch lock.
