I got home today and clicked the "lock" on the key but nothing happened. Unlock and Boot release also not working. I changed the battery (new Duracel 2025) and tried again but not working. I then followed the instructions (from the above link):Fixed your S350 key even if the car does not have any AAM module?
Maybe it was just coincidence that it worked for me? I don't have any knowledge in this area and I appreciate your input. Not sure how I can remove the above link and "instructions" now as the "edit" button is not available. Thanks againSorry but to me this guide is similar to having the key and shaking it while walking around the car twice clockwise and then once counter-clockwise and then pressing the key buttons a few times until they work. The MB key has not needed any sync with the car since the old "IR keys".
Never know if there is a sw bug that gets overcome by a funny procedure like the W211 rear SAM SW got confused at times and only recovered from a power reset (or reset with star).
Show me a workshop instructions document explaining what this sync does and I might change my pessimistic view.
Cheers, just don't want to be giving out bad infoDon't think there is any need to remove the link. On the contrary, better to have it for others to read. More comments from other forum members welcome.
Could be the key just lost its sync. Merc are rather sensitive with this info as keys are normally
