First, open the metal key by pressing the button on one of the four corners to release it. Now, without any special tools, use a flat tool to pry in the gap between the two faces of the key to separate and open them side by side. This way, you will gain access to the slot of the exhausted battery.

Simply push it out to remove it and install the new battery. Be careful not to dislodge the circuit.

For reassembly, just press the two separated faces together.
