The past yr I have this lock and had multiple problems. The first problem is the lock battery dies out very quick approx every 2 months. I had a kwikset older version that i never had to replace the batteries in the 3 yrs I lived there. The other very annoying issue is when you put your hand over the lock for the display to turn on keypad with give you random numbers. When you try to touch the numbers nothing happens and you need to wait until the display turn off so you can turn it back on again and try to have the display work. Sometimes this issue takes several rounds and can take up to 5 minutes to get into your house very frustrating.This issue does happen almost half the time I try to use the lock. I called multiple times to try and have assistance but they just reset the lock and it works correctly for a week then starts getting messed up again and there after.
