Need help with ignition switch
 

I just bought a 2000 Boxster S roller which I'm slowly piecing together. The ignition switch is missing the the key, lock cylinder, and anti theft transducer. What parts do I need to make this thing work without locking up steering? Does the lock cylinder (the part that key goes into) go together with the anti theft transducer? Can I purchase these separately? Do I even need the anti theft transducer?
The ignition cylinder itself seems ok, as I can turn it with a screwdriver at the moment.

Yes you can purchase separately, you DO NOT need the theft transducer. But it does make things easier. With out it you have to flash the ECU to accept a key without a chip command. Usually a Porsche dealer can do this for you, some shops can also. Depends on the equipment they have.
