After doing maintenance on my truck it wouldn't start.1. Checked all fuses and wiring2. Locksmith suggested that the anti theft immobilizer had been activated while working on the vehicle.
3. Truck has no power doors or windows, no alarm system. I have both sets of keys.
4. Local Ford dealership says they don't service anything over 10yrs. Old.
5. Mechanic shop says it's a Ford program they would have to do it.
Anyone knows how to disable or reset the anti theft?
