In a simple and brief manner, we will see how to disassemble and replace the battery in the remote key for the Volvo S40. First, take your remote in hand and begin to pry on the side of the remote as well as on the seam using something thin and sharp.

This will allow access to the internal part, including the circuit board and battery, as shown in the video.

At this point, remove and replace the old battery with a new one of the correct type (in this case, a CR 2016 3V); insert it the right way round before reassembling the two parts of the remote!
