Locate the release button: As mentioned, this is usually a small button on the side or back of your key fob.
Separate the key fob halves: Press the release button and gently pull the two halves apart. Use a small flathead screwdriver if necessary, but be careful not to scratch the plastic.
Remove the old battery: Once open, you’ll see the old CR2032 battery. Gently pry it out using your fingernail or the flathead screwdriver. Avoid puncturing the battery.
Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up, just like the old battery.

Check the battery orientation: Make sure the new battery is inserted correctly with the positive (+) side facing up.
Clean the battery contacts: Use a cotton swab and a little rubbing alcohol to clean the battery contacts inside the key fob. Corrosion can sometimes interfere with the connection.
Try reprogramming the key fob: In some cases, you might need to reprogram your key fob after changing the battery. Refer to your owner’s manual for instructions on how to do this.
