After a few days of positive use, I felt comfortable leaving my keys at home when I went on my walk. The lock worked well for the first few weeks. Unfortunately, that's as long as it lasted. Now I consider myself LUCKY when the lock actually opens. More times than not, I'm left crawling through the bedroom window on the side of my house (after climbing my gate) to get inside my house! The lock has been getting stuck in the lock position and will not open until I manually turn the lock! This is absolutely not what I expected and now I have to leave the front door unlocked when I leave the house! I should have never bought this lock! Be warned!
