Copying Ignition Keys

Copying Ignition Key Assemblies

Tool Required:
J 35628-A VATS/PASS Interrogator

To copy an ignition key assembly, it is necessary to first determine which PASS-Key II key code (resistance value) is needed. The ignition key assembly being copied must be tested to determine the key code. The ignition key assembly may be tested using J 35628-A. To use J 35628-A, turn the tool on, make sure the tool wiring connectors are disconnected and insert the ignition key assembly into the tool lock cylinder. The "Key Code Reader" will display the key code of the ignition key assembly. Obtain an ignition key blank matching this key code and cut it to match the original ignition key assembly.
