How To: Replace Your FAST Key Battery
How To: Replace Your FAST Key Battery
So I got into my car the other day, and the ***** greeted me with a nice "KEY BATTERY LOW" message. Not wanting to get stranded because of a dead fob battery, I did some poking around to see what needed to be done. I didn't see anything related, so here's a quick write-up for you fellas (Yeah. I only said fellas, we all know girls don't exist on the internet).
What you need:
What you need:
- 1 - Set of hands (Ten fingers)
- 1 - Flat head screwdriver
- 1 - Replacement CR2032 battery (This can be found for $2.25 on Amazon)
- 1 - 2 minutes of spare time
- Remove the emergency key.
- Look at the BOTTOM of the key, there should be a little slit here. Use the flat head screwdriver and pop open the back cover.
- Notice the shiny battery being held down by two tabs. Directly on the other side of the tabs, there should be a "slot" where you can gently pry out the battery with same screwdriver.
- Remove new battery from packaging.
- Slide new battery in, it might take some finessing.
- Replace back cover and emergency key.
- Pat yourself on the back for not running to the dealer for such a simple (and cheap) task.
- Get yourself a beer and try to convince your significant other to have some sexy time.

Nice write-up! Some tips (as I have done a few of these). Be EXTRA gentle. The plastic is soft and scratches easily. Put a piece of masking tape on the screwdriver to avoid scratches.

No problem, bro-tato!
If I'm remembering correctly, mine did this too. After awhile it'll come back on, and complain every time you start your car up.

That plastic is really soft! I even triple masked the tiny screwdriver! Had to twist the screwdriver in the tab to get it to open, and that put a little dent in it. The rest was easy. Had to push REALLY hard to get it to close afterwards. Cheers.
