Originally bought the Plymouth set that has a standard keyed deadbolt and non locking handle, but grew tired of having to dig my keys out every time I left the house to lock the door. The keypad makes it easy to unlock/lock the door quickly, and has been helpful when going away on vacation. No need to hand out spare keys to family members to check on pets, just send them the code. Install was easy, pretty much the same as installing any standard deadbolt.
