I forgot to mention that the smart key also communicates via a low power infra red signal to unlock the ignition and enable the start circuit The chinese have been trying to break the code, and make programmers, the fact of the matter is once the key is coded it is done. I have the 8 page flow chart that shows what happens, what has to be done if the keys are lost, or otherwise. It is covered on the 140 DVD, under group 46 (steering) and group 82 (vehicle keys), under certain conditions the EIS,ESL,ECM, MIGHT NOT BE REQUIRED. In the worst case all the components of DAS3 must be replaced and the learning key shipped with it must be returned to MB since it is a one shot useage. The new style remote is usually around $200, with a mechanical key.
