Press the designated button on the casing to release the manual key. Now, simply remove the back cover of the remote (in the video, this is done by hand; if you have difficulty, use a small flathead screwdriver) and voilà! Here is your battery. Extract it from its slot and simply insert the new one you purchased.

It is a CR2032 battery, available at any hardware store and even in large supermarkets. Reattach the cover, and you're done.

As you can see, this is a very simple task that anyone can do and costs very little.
