Step-by-Step Guide
Gather Your Tools
Before you start, make sure you have a CR1620 battery and a small flathead screwdriver. If you don’t have these items, you can buy them online. Links will be provided in the description.
Locate the Indentation
Flip your key fob to the back where the key ring is located. You will see a small indentation or slot along the seam of the plastic. This is where you’ll insert your screwdriver.
Open the Key Fob
Insert the flathead screwdriver into the indentation and twist it. You will hear a cracking sound, which is normal. This action will open the key fob. Set the back cover aside.
Remove the Plastic Piece
Inside, you’ll find a small piece of plastic that indicates the battery type. Use the same flathead screwdriver to push down and pry it back. This will expose the battery compartment.
Extract the Old Battery
You will need a precision screwdriver or a similar thin tool to remove the old battery. Insert it into the small hole at the bottom of the battery compartment and gently pry the battery out.
If you don’t have a precision screwdriver, you can use a paper clip, bobby pin, or a needle. Just make sure it is strong enough to pry the battery out without bending.
Insert the New Battery
Take your new CR1620 battery and place it into the compartment. Make sure the battery is seated properly and clicks into place.
Reassemble the Key Fob
Once the new battery is in place, reattach the plastic piece and the back cover. Make sure everything is securely closed.
