Is your Toyota Highlander key fob starting to feel a bit unresponsive? Perhaps you need to be closer and closer to your vehicle for it to unlock, or maybe it’s just not working at all. One of the most common culprits is a dead or dying key fob battery. The good news is that replacing the battery in your Toyota Highlander key fob is a straightforward process you can easily do yourself at home. This guide will walk you through each step, ensuring you can get your key fob working like new again in no time.
Knowing how to replace your key fob battery can save you a trip to the dealership and some unnecessary expense. Let’s get started and show you just how simple it is to breathe new life into your Toyota Highlander key fob.
What Battery Does My Toyota Highlander Key Fob Need?
Before you begin, it’s important to have the correct replacement battery. Most Toyota Highlander key fobs use a CR2032 3V lithium battery. This type of battery is widely available at most drug stores, supermarkets, electronics stores, and online retailers.
To be absolutely certain, you can check your owner’s manual for the specific battery type required for your Highlander’s key fob. Alternatively, once you open your key fob (as detailed in the next steps), you can simply check the label on the existing battery to confirm the type.
Step-by-Step Guide to Replacing Your Toyota Highlander Key Fob Battery
Replacing your Toyota Highlander key fob battery is a quick and easy task that requires no special tools. Follow these simple steps:
Step 1: Remove the Emergency Key
Locate the small release button on your key fob. This button is usually a small metal or plastic piece situated near the key ring attachment. Press and hold this button while you gently pull out the mechanical emergency key from the bottom of the fob. Set the key aside in a safe place.
Step 2: Open the Key Fob Casing
Now that the emergency key is removed, you’ll see a small slot or notch where the key was housed. This slot is designed to help you open the key fob casing.
Insert a small flathead screwdriver or a thin, sturdy object (like the edge of a credit card or a plastic trim removal tool if you have one) into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid using excessive force to prevent damaging the plastic. The case should pop open relatively easily.
Step 3: Remove and Replace the Old Battery
With the key fob casing open, you’ll see the internal components, including the battery. The battery is usually a small, round, silver disc. Take note of the orientation of the battery (usually the positive side facing up).
Carefully remove the old battery. You can often do this by gently prying it out with your fingertip or the same small screwdriver. Once the old battery is out, insert the new CR2032 battery, ensuring it’s placed in the same orientation as the old one (positive side usually facing up).
Step 4: Reassemble Your Key Fob
Now that the new battery is in place, carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and that there are no gaps.
Finally, slide the mechanical emergency key back into its slot until it clicks securely into place.
When to Consider Toyota Highlander Key Fob Replacement
While a battery replacement will solve most key fob issues, there are times when a full Toyota Highlander key fob replacement might be necessary. If your key fob is damaged, waterlogged, or continues to malfunction even after a battery replacement, it might be time to consider replacing the entire fob.
Additionally, if you’ve lost your key fob, a replacement is obviously required. For Toyota Highlander key fob replacements or if you encounter any difficulties, it’s best to contact your local Toyota dealership’s parts department. They can assist you with obtaining a new key fob programmed specifically for your vehicle.
Replacing your Toyota Highlander key fob battery is a simple maintenance task that can save you time and money. By following these steps, you can ensure your key fob remains reliable and your access to your Toyota Highlander is always convenient.
