Passkey III – transponder ignition key
The Passkey III anti-theft system uses a transponder inside the head of the ignition key. The
exciter inside the ignition lock cylinder energizes this transponder when the ignition switch is
turned on. The transponder transmits a unique signature to the theft deterrent control module.
If the key signature transmitted is acceptable to the theft deterrent control module, the theft
deterrent control module will transmit fuel enable password to the PCM. If the fuel enable
password is correct, the PCM will start the vehicle.
To perform a relearn on a Passkey III system, make sure there is a fully charged battery in the
vehicle. The battery will be used for 30 minutes without the alternator available for charging.
Connect a battery charger to the battery to ensure power is available while programming.
When performing this relearn, all previously learned keys will be erased. Additional keys may
