The key probably needs to be married to the ECU. This may require a Rover dealership or at least a shop that has the equipment to do this.

ok but its the same key and ecu i swap and transfer from a running vehicle, the reason i did this swap is because it had shut down from previous immobilizer issue

I have no idea where the immobilizer info is stored on your vehicle. Most are stored at the ECU, but who knows with Land Rover? It is possible it is stored in another module. You have some serious research to do to get it running.

    My Land Rover will not crank after a 30 to 45 minutes of driving. I will have to wait for 30mins before it crank and sometimes with a smell of fuel. I've changed the crank censor. Any advice?
