Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
The rapid flashing theft light means the computer thinks your a thief and it has disabled the vehicle from starting. A scan tool is needed to see which codes are stored in the PATS system then there is diag and repair needed. If you know the code or can scan it and get it to me we can continue on that diagnosis. Once done the scan tool is needed to reprogram 2 keys to the vehicle.
