MERCEDES RGINALKEY




If all the above works, it seems the module is waiting for you to synchronize the key. I have never done this, but I have read the following steps here https://www.benzworld.org/threads/pr...emote.1286985/ . Read post #4




Dealer suppose to program whatever is necessary to make the key working.
Howcome it is your problem?




Here is my guess, let us see, key was ordered with the correct VIN. It arrived, and somebody forgot the process, the customer MUST bring the car at pickup for synchronization or reprogramming if defective.
Been there before, NO car at the premises, NO key
