I have this lock when I first moved into my new house in 2017.. It worked perfectly without any issue. now all of a sudden the lock just stopped auto unlocking, and sometime wont even open up.. The lock gets jammed, and makes clicking noises.. I contacted support and they were trying to really help out.. it was installed properly and everything .. I did what they wanted me to do to try and fix it ..the conclusion was that the lock motor doesn't work anymore, but since I had it for over a year, I cannot get a new one from the company. their words not mine. instead of sending me a new lock they sent me a 25% discount code for a new lock.. Wow, not a great way to keep a customer... currently looking for new options
