Step-by-Step Guide to Removing the Battery
1. Locate the Battery Compartment
Examine your key fob for a small release button or a notch. This is typically located on the back or side of the fob.
2. Open the Battery Compartment
Using your flat-head screwdriver or plastic pry tool, gently insert it into the notch or press the release button. This will separate the key fob housing, revealing the battery compartment.
3. Remove the Old Battery
Carefully pry the old battery out of its compartment. Avoid using excessive force, as this could damage the fob or the battery itself.
4. Install the New Battery
Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up. This information is usually embossed on the battery compartment.
5. Reassemble the Key Fob
Align the two halves of the key fob and press them together until you hear a click, indicating the fob is securely closed.
6. Test the Key Fob
Verify that the battery replacement was successful by testing all the key fob buttons, including locking, unlocking, and panic functions.
