SecuriLock, also known as Passive Anti-Theft System, or PATS, refers to a security system technology offered by Ford Motor Company that involves an electronic device installed in a vehicle that prevents engine operation without the use of a specific key or token. Ford SecuriLock problems can arise during use, which can often be overcome via some basic troubleshooting techniques.

Damaged Key

Ford SecuriLock system components may not recognize a damaged encoded ignition key. The driver should inspect the key for any signs of chips, wear or other damage that may render it unreadable by the Ford SecuriLock system and use a spare encoded key or obtain a replacement key.

Signal Interference

The encoded ignition key communicates with the installed Ford SecuriLock system via an radio frequency identification device, or RFID. Other electronic devices contained on the driver’s key chain or in his hand may interfere with the RFID signal, causing the system not to activate. The driver should remove all other electronic devices on his key chain or person to eliminate this interference.

Theft Damage

The driver should inspect the vehicle ignition lock for any damage indicating an attempted theft. A forcible attempt to override the Ford SecuriLock system automatically shuts down the engine. The driver should seek out the service of a Ford dealer to restore engine function.
