Normaly its possible te use (or synchrize) max. 8 Infrared Keys to open or close the car.
In my case I have only 1 infrared key, I buy 2 others via Ebay (Germany) but its not possible to synchronize the 2 keys.
I think that I use the 8e key and that is not possible to synchronize another extra key.
I have almost all the docs, technical manuals, special book OEM alarm systems from my car but there is notting about the reset procedure of the Infrared module !
I read on internet that it is very easy to reset the Infrared module (under the back seat R), just a cable from pin 12 (diagnoze socket) to pin 30 of the special MB diagnose box.(Special dealer tool)
Diagnose box is a box that is placed in serie with the Infrared module, the infrared module have 27 pins and my question is what pin from the Infared box I must connect to pin 12 of the diagnose socket ?

Thanks,
