Ford has used 5 methods of Passive Anti-Theft Systems in recent history. Some systems have a stand-alone PATS module, while others have it in the PCM or the instrument cluster. These systems rely on signal communication from a transceiver to a receiver, and will result in a no start condition if this signal is lost or corrupt. This can happen due to component damage, wiring fault, component replacement, or even foreign objects hanging from the customers key chain.
