Step-by-Step Instructions
Follow these steps to replace the battery in your BMW X3 key fob:
Step 1: Open the Key Fob
To open the key fob, locate the button on the back of the fob. Depress this button to separate the two pieces of the key fob. This will give you access to the internal components.
Step 2: Remove the Back Cover
Once the key fob is open, you will see two slots on the backside. The second slot, which does not hold the key for the glovebox, is where you need to focus. Use the key itself or a small screwdriver to pop out the back cover. You should hear a clicking sound as the cover pops off.
Step 3: Remove the Old Battery
With the back cover removed, you will see the battery. Use a small screwdriver or a paperclip to carefully pop out the old battery. Be gentle to avoid damaging the key fob.
Step 4: Insert the New Battery
Take your new CR2450 coin battery and make sure the side with ridges or dots is facing down. This is usually the side without any markings. Insert the new battery into the key fob.
Step 5: Reassemble the Key Fob
After inserting the new battery, align the back cover with the key fob and press it back into place. Make sure it clicks securely. Your key fob should now be ready to use.
