Determining BCM Programed Key Code

To determine unknown BCM key code, use PASS-Key(R) Interrogator (J 35628-A) and Adapter (J 25628-A) and following procedure.

1. Remove knee bolster under steering column. Connect Adapter (J 35628-A) wiring to Yellow 3-pin PASS-Key(R) dash connector at base of steering column. DO NOT connect to steering column wiring.
2. Turn on PASS-Key(R) Interrogator (J 35628-A) and move key code switch to "1" and attempt to start engine using blank key. If engine starts, key code is "1". If engine does not start, turn ignition off and press 4-minute timer on PASS-Key(R) Interrogator (J 35628-A).
3. When timer indicator light goes out, move key code switch to next number and attempt to start engine. If engine does not start, continue trying different key codes until proper key code is found.
