W124 1995 E320 Coupe factory security reset
Does anyone know how to reset the alarm system. I have a key fob that has the MB logo on it and two buttons. One button locks and unlocks the car and simultaneously activates/deactivates the immobiliser. The key fob nolonger opens/closes the locks all of a sudden and this is with new a battery. The key fob has a sliding button on the side.
Any ideas how to get it working again? Also the keys contain a funny looking hexagonal shaped key. Any ideas what that is for? Where does it fit?
