Duplication of Keys

Key Replacement (Spare Key Available)

The J 35628-A Interrogator or equivalent must be used to determine the proper electrical code of the key.

1. Insert the customer's spare Ignition Key into the Key Code Reader on the J 35628-A Interrogator.

2. Press the On-Off Rocker Switch to the "ON" position.

3. A number from 1 to 15 will appear in the window designating the electrical code of the key.

4. Cut a new key having the electrical code determined from the J 35628-A Interrogator.

5. Start the engine using the new key to insure that the key is correct both mechanically and electrically.

Key Replacement (No Spare Key Available)

1. If the Ignition Key is lost and there is no spare key, determine the mechanical code from the code on the Ignition Key Lock Cylinder. The code may also be determined from the dealer invoice for the vehicle, or from the Cadillac Zone Office.

2. Cut a new key to this mechanical code. Use a blank PASS-Key(R)II test key which has a no resistance pellet. This key will be used to operate the Ignition Switch for the remaining steps.

3. Remove the Hush Panel under the Steering Column and disconnect the two-cavity connector leading into the Steering Column.

IMPORTANT:

- If the vehicle is equipped with Supplemental Inflatable Restraints (SIR), do not confuse the SIR 2-Way (yellow) connector with the Ignition Switch Lock Cylinder Harness Connector.

4. Insert the male half of the connector into the female pigtail connector from the J 35628-A Interrogator.

5. Set the key code selector on the Interrogator (J 35628-A or equivalent) to "1."

6. Attempt to start engine using the key made in step 2.

- If engine starts, the key code selector is set to the correct electrical code. Cut a new key having this electrical code. The new key will be the customer 5 replacement key.

- If engine does not start, turn Ignition Switch to "OFF," then turn the key code selector to the next higher position. Wait four minutes and attempt to start the engine using the new electrical code. Use the 4-minute timer on the J 35628-A Interrogator to indicate the 4-minute interval. Start the timer by depressing the "Start" Rocker Switch. The "RED" Indicator will turn off at the end of a four minute interval. This procedure must be repeated until the engine can be started. Cut a new key having the electrical code which allowed the vehicle to start.
