Once the fob has been opened take out the old battery. Replace it with a brand new one. Snap the two halves of the fob together after you've installed the new battery. Test it. If the key fob still isn't able to unlock your vehicle or start it, try holding the fob closer to the ignition switch. The radio transmitter inside the key fob will send a signal to the vehicle's onboard receiver even from just a few feet away, but it's only effective in the event that a battery-powered remote is near the ignition.
