Mercedes Program services

When your Mercedes was manufactured the ecm was married to the VIN number and alsomercedes transponder key to the transponder, security key. This explains why Mercedes are virtually theft proof. The only way someone can steal your car is with your transponder key or a tow truck. So if you have a bad ecm that requires replacement then we will have to program the new ecm to match all the data of your old ecm. This is why you will have to either bring your Mercedes to our shop or mail us the original engine control unit so we can extract all the necessary information required to program the new unit.
