Copying PASS-Key II Ignition Keys

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

This procedure is for copying keys only. It is not a procedure to assure/determine the correct electrical key code.
