First a little background on me: I'm an EE, working in facility power, but I've designed and completed several low voltage projects professionally and at home. I have Raspberry Pis all over my house running everything from cameras to the garage door. Reverse engineering, however, is not something I've done much of. Now for my problem.
I got a Kwikset 912 a while back and installed it on my garage. It powers up and works as expected for a while, but then stops. I can not seem to correlate what is causing the issue. Sometimes it works for a day, sometimes it several days. When it stops working I put my code in and it just freezes up. No attempt to turn the lock, no more beeping when I press the keypad, it just stops responding. If I pull the batteries for a couple hours, then put them in I get another day or 2 or 3 of operation before it does the same thing. They've sent me a replacement, so I can play around with this one and try to fix it. Any suggestions on where I should start?
