Mine is equipped with a Clifford after-market alarm.

I suspect the original MB ATA function is still in place - need to check under passenger side floor mat.

Did these cars come new with a remote hand-held device?

If not, how is the MB factory setup armed and disarmed?

I know this may sound dumb to some, but again, the alarm system that came with the car is not the factory setup, so I simply don't know.

Thanks for your time.
