no my keyless entry is not an actuator.. it is a real system that is made for audis and mercedes.. it is also made for the w124. It hooks onto the vacuum pump and the remote controls it. I can lock and unlock through the vacuum pump using my remote. HOWEVER the locking pumps and alarms are different mechanisms... Unlocking the car with the pump does not disarm the alarm... the key however triggers both the mechanism.. it sends a pulse to the alarm to disarm it and also send a signal to the vacuum pump to unlock the car... as of right now i have only managed to hook up my remote entry into the vacuum pump... how do i make my keyless entry unit send a signal to disarm and arm the alarm?
