Soooo, I stopped by Hendrick MB in Hickory, NC and purchased a $30 key - awaiting delivery. I also noticed a horn in the engine compartment near the passenger side front at the EGR vacuum solenoid. Does anyone know if this is an alarm system? It appears to be stock. If so, how did that system function w/o a remote? or Is this a magical function of the master key and central locking system?
