PATS system is also known as Securi-Lock® in North America. PATS uses radio frequency identification technology to deter a drive away theft. Passive means that it does not require any activity from operator. PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code. Each encoded ignition key must be programmed into vehicle before it can be used to start engine. For additional PATS information, see appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT.
