Hi Everyone, My apologies in advance if I am being redundant on this topic. I have a 2006 CLK 350 Conv with 86k miles clean car I purchased about 6 months ago from first owner. When I purchased the car the owner stated when he changed the batteries on the FOB the keyless go and push start stopped working. I find it hard to believe since both keys dont work(keyless go and push start function ).
Both Keys unlock and lock the car, trunk panic etc and turn the car on ( when the key is in the iginition BUT the keyless go function doesnt work also the push start. When I sit inside the car it says FOB not detected, when i press the push start on my shifter i hear a noise much like a hissing sound telling me the push start is trying to do somthing but not starting the car. Any advice would help, Not worth taking to the dealer and paying a few hundred to thousands for the repair. I have also heard not all Mercedes keys are Keyless go. Mine is
