Any ideas where I can purchase replacement flip out key fobs and have the keys cut in DFW area for my 2002 SLK320. Just bought the car and it came with one and the remote wont do anything. Not sure if this is any kind of transponder key or not, but the key does unlock and lock the doors and starts and operates the car. Not really wanting to deal with the dealerships if I can avoid it. Thanks in advance.
