Model: Smart Forfour MK 1, W454 - Years 2004-2006

To replace the battery in the key of a Smart Forfour car, first of all you need to have a small screwdriver with a star tip, a small screwdriver with a flat tip and the correct model of the battery to be replaced, i.e. flat type CR 2016 3V. We take the key and unscrew the small screw on the back of the same; insert the tip of the flat-tip screwdriver into the edge of the key body and lever it up to open it. At this point we extract the exhausted battery and proceed to replace it and then close the body by fixing the screw removed initially.
