Pic. 7.78. When a client has two or more valid keys
Note. If you still cannot reprogram the immobilizer, check the number of working keys.
Replace the key or perform a key reprogramming procedure.
To make a duplicate key or replace an immobilizer element (key and/or PCM), the customer must bring all the keys to the dealer.
This is because pre-programmed key IDs are cleared from the PCM when reprogrammed.
Do not transfer the PCM from another vehicle. Otherwise, the engine will not start.
Do not replace the PCM with a new one for troubleshooting purposes. The key ID and code word will be programmed into the new unit and cannot be used later for other vehicles, even if you find out that the old unit is good.
The immobilizer cannot be disabled.
Make sure that all registered keys allow the engine to be started after the reprogramming procedure. Wait at least 5 seconds before using the next key.
When the client does not need to register more than two keys, the following operations can be terminated after registering two keys.
