My 2003 Thunderbird randomly won't start. Acts like it's security issue.

Asked by Sep 30, 2013 at 03:57 PM about the 2003 Ford Thunderbird Premium Convertible

Question type: Maintenance & Repair

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.

Your problem is most likely do to the ANTI-THEFT system.Go to RADIO SHACK and buy a can of electronic contact cleaner (aerosol type). Spray it into your ignition lock and spray it onto your key (then wipe the key clean with paper towel). Wait 15 minutes before trying to start your car.

Had the same issue here. Turned out to be starter relay NO.15. Changing that part solved the problem.
