Find a small knife and get your key ready. Be sure to check your battery specifications.  I know the 1999 - 2000 models take two batteries from what I can remember, and were smaller in size.  My 2001 is a 2032 3.0V battery.

Slip the knife in between the line as shown in the picture above.

Twist the knife down, this will lift it off the locking plastic that keeps the key and alarm section together.

Now that you have split the two sections, separate them into two.

Take the remote side since you are changing the battery and put your finger on each end and pull.

Once you have pulled the two sections apart you will end up with two pieces as shown in the photo above. You will now clearly see the battery. Be sure not to touch the computer board if you are not wearing any safety anti static equipment (don't rub your feet on carpet and touch the computer or you will fry your remote).  This is just a warning which I'm sure many already know.

Get your battery out (I choose an Energizer brand) and get the remote section ready for the new battery.

Place your knife into a good spot so you can twist the battery out

Now that you have the battery out put the new one in. Be sure you wipe the grease off the battery (I know my hands were pretty sweaty and greasy and had to wipe off the grease this will keep things flowing better).

Reverse the entire process and your done!
