In order to replace lost PASS-Key® II ignition keys, determine the required mechanical cut and the key code to start the vehicle from the vehicle invoice.

If the codes are not available, use the following steps in order to determine the code:

1. Determine the mechanical cut from the following sources:

•	The code sticker on the steering column (ignition) lock cylinder

•	The original key knock-outs

•	If the mechanical cut can not be determined, replace the steering column (ignition) lock cylinder.

2. Use the J 35628-A and the J 35628-90 , in order to determine the correct key code. Use the following procedure to determine the key code:

2.1.	Connect the adapter harness (48 way) connectors to both the body harness and the steering column harness of the steering column inline connector C202.

Important: Do not connect the adapter to the ignition lock switch.

2.2.	Connect one adapter harness (2 way) connector to the harness side of the steering column (ignition) lock cylinder connector.

2.3.	Connect the other end of the adapter harness (2 way) connector to the interrogator.

2.4.	Turn on the J 35628-A .

2.5.	Place the key code switch in the number 1 position.

2.6.	Start the engine with the new mechanically cut key.

If the engine starts, the key code is 1.

2.7.	If the engine does not start, turn the ignition switch to the OFF position.

2.8.	Press the 4 minute timer on the J 35628-A .

2.9.	When the timer light turns OFF, or the START CAR message is displayed, place the J 35628-A key code switch in the next position (2, 3, 4...).

2.10.

Attempt to start the engine.

If the engine starts, you have the correct key code. Proceed to the next step.

If the engine does not start, perform the previous 3 steps.

2.11.

Make a new ignition key using the correct key code and the mechanical cut.

2.12.

Ensure that the new key starts the engine.
