Hi there have been trying to code a blank key on Mercedes C320 204 chassis 2008 model.
Iam using a Siemens blank key but every time I start the process comes up with the blank key failed.
I did tr y a BE Chinese key which coded but it had no reception with the central locking had to be very close to vehicle for central locking to work.
I did test the original key and that worked fine from a long distance.
If someone could let me know what I'm doing wrong.
Cheers peter.
