Key Programming

[Guy Greenwell]

Does anyone know how to programme an electronic key to match a car.
My recently aquired C250 TD has only one key which works but I have been given another which does not. I did read that it is possible to make a key match a particular car. Or must I order another from M.B.
Can anyone help please?

I had the same problem when I bought my car. If you have an owners manual
it tells you exactly what to do. If not try this; Point TRANSMITTER to the receiver of the door or boot and briefly press transmitter button. now put key in ignition lock and turn to position 2 within 30 seconds. Your key should now be reprogrammed.
