Not sure if this question belongs here, but I’ll take a shot.
My apartment fob controls the parking gate, elevator entry to the floor, entry doors. Recently put in a new battery and I can click it to activate the parking gate.
Today, I swipe the fob in front of the reader to enter the building, I swipe it in front of the reader to get access to my floor. Works just fine.
Half hour later, I head back down toy car. Fob not working. The fob reader in the elevator doesn’t detect it. Eventually, kind neighbor swipes me to my car. I hope that the fob works now…it doesn’t. Tried to swipe it half dozen more times… eventually the reader detects the fob and it works. Unbeknownst to me why. I tried both elevators in my building and the door, and they all failed initially. So I know the problem was my fob, not the readers.
Dear community, any ideas what my fob’s problem was and how do I make sure this doesn’t happen again?
