Once you've opened the fob, pull out the old battery and then insert an alternative one in its place. Once you've inserted the new battery and the fob is closed, snap the two halves together and test it. If the key fob won't unlock your car or start it then try holding the fob closer to the ignition switch. The radio transmitter in the key fob is able to transmit a signal to the car's onboard receiver from a short distance, but it's only effective in the event that a battery-powered remote is in close proximity to the ignition.

It might seem unlikely that your key fob would require a new battery, but it's better to be prepared rather than wait for it to occur at the worst possible time.
