This is the lock I never knew I needed! Installation got a little confusing but that was my own fault. Setup was super easy and getting it programmed was a cinch! My kids love how easy it is to get in the house now and the fact they don’t have to keep up with a key is very nice. I won’t have to keep making copies when they lose them! I love that you can have a code for each person. Makes letting in the landlord and the dog sitter in a breeze. No problems. No complaints. Perfect. Definitely recommend!
