Hello. My doors would not lock for months. All of a sudden. And when I would press the lock button on the fob, it would beep twice. Indicating that my doors were still unlocked. Playing around with my key fob one day. I accidentally pressed the panic button a few times. Now my doors lock and the alarm sets. No more unlocked doors and no more double chirps. It’s a miracle! I hope this works for anyone else having the same issue.
