Step-by-Step Instructions

Follow these simple steps to replace the battery in your key fob:

Remove the Internal Key

First, locate the silver button on the left side of your key fob, near the bottom. Hold down this button and pull out the internal key.

Pry Off the Back Cover

Use the internal key to pry off the back section of the plastic cover. Insert the key into the keyhole, but not too far. Apply pressure by pushing up towards the back piece of plastic until you see a small opening in the seam. Once you see this, commit to it and pry the cover off.

Remove the Old Battery

Now, use a flathead screwdriver or your fingernail to gently lift the old CR2032 battery out of its compartment. Dispose of the old battery properly.

Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing down. Insert it into the compartment and make sure it sits flat.

Reassemble the Key Fob

Place the back cover on top of the front section, ensuring everything is aligned. Squeeze the two pieces together until they click into place. Finally, insert the internal key back into its slot.
