this means that the type of the transponder key is not correct, or this key is already programmed to the car!
Do NOT repeat the programming procedure if immobiliser shows different digits "1-2" or "2-3"! Just switch ON ignition
with NEW Megamos ID48 transponder key! If you want to program more than one new key, repeat again the same procedure for every next key.

Press "Options"-"Transponder Check". Software will connects immobiliser. After successful connection, press
"Read ECU Info" button. All information about the transponder key will be shown on screen. "Transponder Variable Part YES!"
means that secret key of transponder is valid for the car. "Transponder Fixed Part YES!" means that ID number of transponder
is stored into immobiliser's memory. These two parameters must be "YES", otherwise immobiliser will
block engine ecu, and engine can't be started. "Transponder Locked" is not important for immobiliser. If it is "YES",
this means that secret key and user pages of this transponder key can not be re-programmed for other car!
