Locate the release slot: On the side of your key fob, you’ll see a small slot. This is the key to accessing the battery compartment.
Insert and pry: Gently insert your flat-head screwdriver into the slot and apply gentle pressure to pry open the key fob casing. You’ll hear a slight click when the two halves separate. Be careful not to damage the plastic.
Separate the halves: Carefully separate the two halves of the key fob. You should now see the CR2032 battery nestled inside.
Remove the old battery: Using your screwdriver or a small pick, carefully pry the old battery out of its compartment. Again, be mindful of applying too much pressure and potentially damaging the fob.
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing upwards, just like the old battery.
Reassemble the key fob: Align the two halves of the key fob and press them together firmly until you hear a click, indicating they are securely closed.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.
