The key may be faulty.

It has 3 key all inside the bcm file. No one work att the moment . The remote not work too.

This car usually loses the key code in the engine control unit (ECU). I disable the security system in the ECU, and it works.

If the engine control unit number is [number] continental 76.1

, you must extract the file, disable the key code, and download the file again to complete the process.

I have a file for this car with the key code disabled if you want to buy it.

The ecu is mt80
