Hey everyone! I have been searching far and wide for an answer to this.. I own a 2012 Scion tC and it has been a solid car as of yet. A couple days ago I attempted to lock my car with my key remote. It did the normal single beep, then it beeped twice, then it beeped three times in a row, and eventually it beeped once more. I scratched my head so I tried to open the driver side door and it was open. Within 4 seconds the alarm went off. From here I have attempted to using the key to lock the door manually as well as locking the car from the inside then shutting the door. All attempts end up with the weird sequence of beeps [1 , 2 , 3 , 1]. If someone could point me in the right direction I would be very thankful. Thank you for taking the time to read, I really appreciate it.
