Bought at auction...and I have a key. It worked on the door locks, for a short couple of days, but never did it let me turn the key or start the car . It won't budge. So instead of going to the dealer and having them order one from Germany and then towing the car two cities away to the dealer for them to then program the key (which is the only way they will do it.) Could I just buy a used ignition switch and key on eBay/Amazon and slip them in and go? I have taken the chip out of the case and the coil had already been broken or was broken when I took it apart. So I don't know if they are replaceable or if it's worth even trying. Hence my new ignition and a key for $70-$80 rather than $300 plus from the dealer.
