incorrect the vehicle will not start.
PATS
Passive Anti-Theft System (PATS) uses a specially
programmed key to start the vehicle, similar to the
Immobilizer. It uses an antenna ring around the
ignition cylinder to energize a small transponder chip
hidden in the ignition key. When the ignition is turned
on, the chip is energized and the antenna ring sends
the code to the PATS control unit. If the code is
incorrect the vehicle will not start.
