I have just tried to sync a Mercedes key and no joy.

I'm now at a crossroads, do i replace the skreem or the bcm?

Im guessing at replacing the skreem as it would appear that the car is not receiving the signal from the key.

would there be any other symptoms of a bad skreem? i dont get my flashing indicators when i lock the doors manually. is this normal?

sorry for all the questions. all the help is greatly appreciated
