Ignition Key
WARNING: This page is about a different car, the 1990 Cadillac Allante. However, it is still accessible from the selected car via links, so may be relevant.
The ignition key for cars equipped with PASS Key is an assembly of a typical square ignition key blank and a resistor pellet. The key blank and resistor pellet are not serviceable separately. There are 15 different ignition key assemblies, each with a different resistance value. The ignition key also has mechanical cuts similar to non PASS Key ignition keys.
