First, press the designated button on the back of the cover and remove the key from the shell. Now, using the same key (or a flat-head screwdriver to avoid damaging the key), lever in the slot of the remote as shown in the video.

This will open the shell in two halves, giving you access to the battery: if your aim is to replace the flat battery, simply remove it and replace it.
