Ford Focus: How to change a battery

How do I change the battery in my Ford Focus key?

Press the grooved buttons on the side of the smart key, then lever the raised centre section on the rear off. Pop the metal key out and, using a metal screwdriver split the key in half by inserting the screwdriver into a slot inside the end of the key. You can then access the battery, prising it out and replacing it.
