Replacing A Lost VATS/PASS Ignition Key

TOOL REQUIRED:
J 35628-A VATS/PASS Interrogator
J 35628-95 VATS/PASS Interrogator Adapter

To replace a lost VATS/PASS ignition key, it is necessary to determine the original mechanical cut and the resistor key code.

The mechanical and resistor key codes should be recorded on the vehicle invoice. If this information is available, use it to create a new ignition key. If the vehicle invoice is not available, record the Vehicle Identification Number (VIN) and call Buick Roadside Assistance: 1-800-252-111 2. If the vehicle invoice is not available and Buick Roadside Assistance is unable to provide the vehicle key codes, perform the following procedure.

Important
^ Do not disconnect the yellow two-way SIR connector.

1. Create a "blank" (non-resistor) ignition key with the proper mechanical cut.
2. Connect the J 35628-A wiring to the ignition lock cylinder connector located at the base of steering column. Do not connect the J 35628-A to the steering column side of the ignition lock cylinder connector.
3. Turn the J 35628-A on, turn the key code switch to "1" and attempt to start the engine with a properly cut key. If engine starts, the resistor key code is "1".
4. If the engine does not start, turn the ignition "OFF" and press the 4-minute timer on the J 35628-A.
5. When timer light goes Out, turn the key code switch to "2" and attempt to start the engine. If engine starts, the resistor key code is "2".
6. Continue trying to start the engine using different resistor key codes until the proper resistor key code is found.
7. Make a new ignition key with the proper resistor key code and mechanical cut.
