check with your dealer before buying a key off of ebay, some people are claiming the keys can be reprogramed by the dealer when in fact they cannot, i can't tell you how many pissed off customers we deal with that bought new keys off ebay, showed up for us to reprogram them, only to be told they waisted their money, we are mercedes but i would check, we also need photo id, proof of ownership and a form filled out before we can even order a key, ALL of our keys come from ft worth, no cutting at the dealerships.
