Hi, I recently bought a 1997 SLK230 which turns out to be a Japanese import model. Only one key was supplied with the vehicle. I bought a new key from my local Merc dealership which starts the engine but the fob will not lock or unlock the doors. Does anyone have experience of imports and can inform me whether the frequency would be changed for the doors only or if it is more likely that I have been sold a faulty fob? All information and ideas will be gladly accepted. Regards reecey7
