It's been discussed a lot in the past - because it happens to someone's car regularly here. I have bought many various salvage Boxsters and have done the swap of a similar year and model Key fob, DME (ECU) and Immobilizer Box (Central Locking Unit). The signal transducer (996.618.159.01) is not needed. The drawback of doing it this way is that that car's specific info such as the VIN, detailed equipment, and engine history (over-revs) will not be in the parts that you swapped in. It will lead to problems if you have it serviced at a Porsche Dealership in the future.

I'd recommend ECU Doctors for a reliable repair if you value the car enough for the expense. Otherwise having the clone done is a better option that swapping parts from another car.

In my case, I recently bought a 2002 that hadn't run for over a year and the immobilizer board was beyond repair. To get it running and start evaluating the car, I swapped in the fob/Immo/ECU from a 2001. I'll decide if I want to get the original immobilizer cloned. The car needs a lot of maintenance - suspension, paint and minor body work and I have yet to decide if I want to put money into making everything right or just have it functional.

Note: There are many versions of immobilizer box. If you buy one, make sure that it is the same part number as the original.
