Keychain remote needs reset every 12 hours
Every 12 hours the system begins to beep and then says "Sensor 1 Keychain remote failure". We have to hold down the lock and unlock buttons simultaneously to reset it, but then it only lasts for 12 hours and we have to do it again. It's really annoying, but I don't know what to do to get it to stop.
