How do you open a BMW X3 key fob?

My key fob has been acting up lately, so I want to go in there and change the battery. Can you tell me how to open a BMW X3 key fob?

Sorry to hear that your key hasn’t been working as it should! Here’s how to open a
BMW X3
key fob:
  • Press down on the black button on the bottom right-hand corner of your key fob
  • Pull on the bottom of the key fob to release the physical metal key
  • With the metal key set aside, look for the “+” and “-” symbols on the bottom of your key fob
  • Using a small flathead screwdriver (or your finger, if you’ve got long and strong nails), pry off the back covering of the key fob by inserting it in between the “+” and “-” symbols.
And that should do it! Your BMW X3 key fob should now be open. If you think the battery is the issue, you can also use the same flathead screwdriver you used to open the fob to pop out the battery.
All in all, it’s pretty easy to open your BMW X3 key fob. Shopping for
