Immobilizer Antenna
 

I've got a '99 S80. When I try to start it, the engine cranks but it does not start. The message screen said something about Engine Immobilizer. I have tried both keys, locking & unlocking the car 5 times, and nothing has worked. After reading through the forums I assume I need to replace the immobilizer antenna. Can I replace the immobilizer antenna myself? Or do I have to take it in so they can update the software so the ECU will talk to the antenna?

Thanks

You can do it your self no software needed.

Thanks for the answer.
