My 2003 Thunderbird randomly won't start. Acts like it's security issue.
Use key fobs to lock and unlock doors, but it doesn't fix the problem. Had problems with it a couple days last week. Had no problems with it this weekend. Went to start it up this morning and it wouldn't do anything. My lights do come on and they are bright. The steering wheel moves as it normally does. The security light on the dash flashes really fast. Not sure what to try to fix this issue.
