I haven't had ANY issues with this lock whatsoever, and I was a little worried I might with any lock like this. I use several different lock codes considering I have such a big family and everyone has their own code, and it's nice that this lock can use up to 50 different codes! The lock works really well, another plus because my door is a little off but it still locks all the way rather than just pulling back in and requiring a second try. It was also really simple to install! The instructions could be a little better but I was still able to get it figured out by myself and up and running.
