Procedure D - Erasing Key Codes

This procedure will erase all known vehicle key codes, except for the code of the vehicle key being used to perform the procedure. An example of when this would be required is if a customer were to lose a set of keys or have them stolen, the keys may be erased, making them unable to start the vehicle. After the key codes have been erased, any existing keys may be registered using Procedure A.

1. Turn the ignition ON with an already learned master key.
2. Select Programming Additional Keys on the scan tool. The security indicator will be briefly illuminated.
3. Within 10 seconds of the scan tool's instruction, turn OFF the ignition and remove the key.
4. At this point, the vehicle keys are erased. If vehicle key registration is desired, refer to Procedure A.
