I have the same problem, some kind of security issue. The radio will not even ask for a code, the automitic locking sysyem, even manual, will not work. That includes the fuel door. It was preceeded by the alarm going off 3 times and I disconnected the battery every time. After 1st time radio still worked, after 2nd time asked for code, after 3rd time the radio and locking system were not working. How can I open the fuel door manually?
