Replacing Lost Ignition Keys - PASS-Key II

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 adapter harness J 35628-90 and the following procedures:

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 starter, the key code is "1".

3. If engine does into start, turn ignition off and press 4 minute timer on J 35628-A.

4. When the 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.
