Anything like this?



If so it's for the MBSS alarm/immobiliser - IIRC you can insert it into the control box under the bonnet to deactivate the siren. Although billed as the 'Mercedes-Benz Security System' MBSS was actually an aftermarket Scorpion unit, fitted to the cars after arrival in the UK. The paperwork for this came with my car:

and, or a valet key.

Thank you ! Thank you ! for the information.

Please can you take a photo where to insert under the bonnect when you have time

Do you know if i insert in the control box does it reset the alarm and immobiliser,i cant start up the car i think the immobiliser is on and the key fob cannot switch the immobiliser off.
