I had a friend who bought a 2001 E320 with the same problem with the temp lcd, and he had it fixed, so I know it can be done.

Regarding the key....they are VIN specific, and need to be programmed by the dealer.

The advice on the forum is to never buy a key on ebay. Try the search function to see what you can find out.
