What You’ll Need to Change the Battery in Your Toyota Highlander Key Fob

Before you begin, gather the following:

• A new CR2032 battery (widely available at most stores). Don’t try to substitute with another type – the CR2032 is specifically designed for this purpose.
• A small flathead screwdriver or a similar tool for prying. A plastic tool is ideal to avoid scratching your key fob.
• A well-lit workspace. Good lighting makes the process easier and helps prevent losing small parts.

Step-by-Step Guide to Changing Your Toyota Highlander Key Fob Battery

Follow these instructions carefully:

1. Locate the release button: On the side of your key fob, you’ll see a small button or notch. This is the release button for the auxiliary key.
2. Remove the auxiliary key: Press the release button and slide the auxiliary key out of the fob.
3. Separate the key fob halves: Use the flathead screwdriver (or plastic prying tool) to carefully pry open the key fob casing. Start by inserting the tool into the slot created by the removal of the auxiliary key. Gently twist or lever the tool to separate the two halves of the fob. Be patient and work your way around the edges to avoid breaking any clips.
4. Identify the old battery: Inside the key fob, you’ll see the CR2032 battery. It’s usually secured in a small compartment.
5. Remove the old battery: Gently pry the old battery out of its compartment using your flathead screwdriver or prying tool. Be careful not to damage the contacts.
6. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces upwards, just like the old battery.
7. Reassemble the key fob: Align the two halves of the key fob and press them together until they snap securely into place.
8. Reinsert the auxiliary key: Slide the auxiliary key back into its slot until it clicks.
9. Test the key fob: Try locking and unlocking your car to make sure the new battery is working correctly.
