Thanks for the info 97 SL320. I tried eBay for the housing but mine is a 1 button housing. The only ones available had three buttons. I'm just going to spend whatever it takes to get a new one from Mercedes. I will get a discount and hope that my new key will have the latest upgrade. Besides I don't buy chinese unless it is "take out"
