Hello,

This is my first post on the forum, but I have been reading for quite some time.

I have a W204 2008 C350. My issue is that the (one and only) key fob only works within about 1 foot of the rear glass of the vehicle.

Of course I have replaced the batteries, as well as buying a new case and switching the circuit board over.
Neither of these made any difference at all.

Have not taken to dealer as I am a broke college student and already know a large bill would be headed my way.
Any advice is much appreciated.

Thanks!

Try a new remote, it might be old and tired. Do not buy aftermarket, go to the dealer and get a Mercedes programmed remote for your vehicle.

If that does not work, you may have to replace the antenna. Had to do this on my sons C320 and yes, ................... not cheap.
