1) Replace the battery. Most vehicle key fob remotes just split open. Usually there is a small slot on the side of the remote where you can stick a small flat head screw driver in and pop the case open. There you will find a small coin battery. The coin batteries have numbers on them, usually something like CR2032. That is the battery size. You can find new coin batteries pretty much anywhere these days, and if you are having a hard time finding them at a local store you can order them online at keylessentryremotefob.com.
2) Reprogram the remote. Sometimes when the batteries in the remote go bad, or even if you had to replace your car battery, the key fob will need to be re-programmed to your vehicle. Most of the time you can program a key fob remote yourself with a few steps of turning the key in the ignition, pushing some buttons on the door, and pressing the buttons on the remote.
