Duplication of Keys - PASS-Key II

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 by 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" will display the key code of the Ignition Key. Obtain a key blank matching this key code and cut it to match the original key.

REPLACING LOST PASS-Key II IGNITION KEYS
To replace lost PASS-Key II Ignition Keys it is necessary to determine the mechanical cut and the electrical key code.

The mechanical and electrical codes are recorded on the vehicle invoice. If these codes are available, use them to create a new key. If they are not, follow the procedure below.

The mechanical cut must be determined first. The mechanical cut can be determined from the key code on the Ignition Lock Cylinder or from the original key "knock outs". If the mechanical cut cannot be determined, the Ignition Lock Cylinder should be replaced. Make a key with the correct mechanical cut to use while determining the proper electrical key code.

To determine the proper electrical key code use tool J 35628-A and the following procedure:
1. Connect the tool wiring to the PASS-Key II dash connector at the base of the steering column. Do not connect to the Steering Column wiring.
2. Turn J 35628-A on and place key code switch to "1" and attempt to start engine with proper mechanically cut key. If engine starts, the key code is "1".
3. If engine does not start, turn ignition "OFF" and press 4 minute timer on J 35628-A.
4. When timer light goes out, or the "START CAR" message is displayed, place key code switch to "2" and attempt to start engine. If engine starts, key code is "2".
5. Continue trying different key codes until proper key code is found.

Make a new key with the proper PASS-Key II key code and mechanical cut.
