How to Disable a Car Alarm on a 2003 Mercedes Benz C240


1. Turn off the C240's engine and open the hood. The fuse block is situated behind the C240's battery.
2. Remove the C240's fuse block cover. On the underside of the fuse block cover is a fuse puller. Remove the fuse puller from the cover.
3. Remove the fuse numbered '8' in the fuse block. Use the fuse puller. If you wish to enable the car alarm, plug the fuse back into the '8' slot.
4. Place the fuse puller back onto the cover and place the cover back onto the fuse block. Close the hood.
