hi, just got an original keyless entry from e320'95 w124. and I've done it the installation and working great ( for the lock and unlocking only)

i believe the keyless / remote has more functionality than just lock and locking the the door,
like rolls up / down the 4 windows at the same time when the button being pushed for couple of second

another option is, it has an anti engine starting when the door being locked by remote ( not manually)

my questions
1. anyone has any idea how to install these option ???
2. can i get the diagram for the installation ???

well, if it is possible please email me.... my email is a_prakersa@yahoo.com


thanks guys......
