### ⭐⭐⭐⭐⭐ Review
*by C***R on 7 March 2024*

This is exactly what I was looking for! I used this on the door into my garage. I wanted to keep my younger kids out since I had toxic liquids stored in there. I had a locked door set on, but it meant that if I locked it I would have to remember to bring the key every time I went into the garage and I am in and out of the garage many many times. This door lock is perfect since it automatically locks when I close the door and is easy to unlock using the key pad. I was a bit confused about the "anti-peek" feature but it just works. If I think someone is watching I just randomly enter a bunch of numbers and then in the middle of that random sequence, enter my real four digit code followed by some more random numbers. Once done, hit the # key and the thing unlocks! I love this. Way easier to install than some people have said and programming is a snap!
