I wonder if anyone could help me besides a mechanic. I asked my teenager to take out some stuff from the vehicle, he used the remote key and the regular key to lock/unlock/? the doors. Since than the remote key is not functioning, the red light on the remote blinks but it does not do anything to the vehicle, no beep, locking, or unlocking. In addition, the alarm is not activated. If you have any ideas please share them with me.
