    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.

    You can get coils on eBay. You need to change a lot more than just key and switch for it all to work.

    So, in your opinion it would save Alot of potential head ache and time to just skip the b.s. and go get a synched key from Mercedes? How frustrating. I don't see this major effort in security/smart keys/getting new keys being such a nightmare and an expensive one at that doing much more than absolutely frustrating Mercedes owners rather than thwarting potential car thieves. not even a locksmith can make you a new one. . Thanks for the answer. .

    As suggested try a replacement coil but if that doesn't work you need a replacement key. There are third party key suppliers (replacement Mercedes Keys for example) and companies that can fix them (JohnnySBC on here).
