Good morning, I have a w210 that has lost the key remote(the cover) this car has LEDs on rear view mirror and ifz behind the cluster with antenna on key slot now I found another remote and a pcf7935 chip but when I try to load the ifz dump in FVDI to make transponder it refuses saying the file is not from the selected make but when i load it as an infrared key it accept. now I ask which key does it use? I load dump from ifz please help,or if anyone can generate a file to write to pcf I will be thankful.

your attachment has corrupted content. and the key that works with this system has a 93c46 memory, the infrared remote control with a single button

can you give more information about the car? (vin - or year and engine type)

ok am going back to car I will send the info you require and I will try to read the ifz again, 1 thing that puzzles me though is why is there a transponder ring on ignition

Check if there an immobox under passenger feet under the carpet if there is the car use transponder key
If no one there and only behind dash thatean ir key without transponder
