Small anecdote…
I’m at work and the wife comes home from her shift. She can’t get the garage door open either with her transponder or the keypad. She try’s the keypad 5 times and decides I’ve changed the passcode. She gives up and goes inside thru the front door. The power is out, she goes to bed. I come home later and she asks me if I got the garage door open. I say yes, she then accuses me of changing the passcode. She mentions the electric was out for a little while but sees no relation between the electric being out and garage door not opening for her. She asks if I’ve changed any other passwords. Errrh..
