DIY: Key Battery Replacement
I was driving today and noticed that my dash informed me to replace the battery in my key.
Materials: New battery (CR2025 3v) and small blade.
Here are the directions:
Step 1. Pull the grey lever to the right and pull out the L shaped key.
Step 2.
Step 3. Turn the key to the back side and insert the Key into the left side.
This will press out the back key cover.
Step 4. Take a blade and pull out the battery.
Step 5. Install the new battery and replace the cover. Then reinsert the key.

Nice trick with the L shaped key to undo the battery compartiment. Never thought of that and I end up with broken nails... 
I'll certainly try it like that next time I need to change the battery.
I'll post a link to this DIY in the DIY thread if OP doesn't mind
