Did a search and couldn't find this topic. After close to 4.5 years, the battery in my smart start fob has died. I'm having a hard time getting the back off so I can replace the battery. I did it once, back in November 03 and recall having a very hard time. I looked on the owners manual and still having a hard time getting the back off.
