Owning a 2015 Toyota Highlander comes with a sense of dependability, but what happens when your key fob decides to take an unexpected vacation? A malfunctioning key fob can be incredibly frustrating, leaving you stranded and unsure of what to do next. If your 2015 Toyota Highlander key fob is giving you the cold shoulder, don’t panic! This comprehensive troubleshooting guide is here to help you get back on the road and back in control.
Common Reasons Your Key Fob Might Be Acting Up
There are a few usual suspects when a 2015 Toyota Highlander key fob decides to stop cooperating. Let’s break down the most common culprits:
- Dead Battery: This is the most frequent offender. Just like your TV remote, your key fob relies on a small battery to send signals to your Highlander. Over time, this battery can drain, leaving your key fob powerless.
- Signal Interference: Believe it or not, other electronic devices, radio waves, or even physical obstructions can interfere with the signal between your key fob and your vehicle.
- Key Fob Programming Issues: Sometimes, the issue isn’t with the key fob itself but rather a communication breakdown between the fob and your Highlander’s immobilizer system. This can happen if the programming is accidentally erased or corrupted.
- Physical Damage or Wear and Tear: If your key fob has taken a few too many tumbles or has been exposed to the elements, it’s possible that physical damage or wear and tear is preventing it from functioning correctly.
Troubleshooting Your 2015 Toyota Highlander Key Fob
Before you call for a tow truck, let’s try some DIY troubleshooting steps to see if we can bring your key fob back from the brink:
1. Check and Replace the Battery
This is the first and easiest step. Most 2015 Toyota Highlander key fobs use a CR2032 battery, readily available at most stores.
How to Replace the Battery:
- Locate the small release button or tab on the back of your key fob.
- Gently pry open the fob casing using a small flathead screwdriver or a coin.
- Carefully remove the old battery and note its orientation.
- Insert the new battery, ensuring it’s facing the correct way.
- Snap the fob casing back together.
Pro Tip: Avoid touching the battery’s flat surfaces with your fingers, as this can transfer oils that might shorten its lifespan.

2. Test for Signal Interference
Electronic devices, security systems, and even large metal objects can sometimes mess with your key fob’s signal.
Try this:
- Move away from any electronic devices that might be interfering.
- Try using your key fob from different distances and angles to see if you can establish a stronger signal.
Still no luck? Try holding the key fob close to the start button on your Highlander’s dashboard while pressing the button. This can sometimes bypass interference.
3. Inspect Your Key Fob for Damage
Take a close look at your key fob. Are there any cracks, loose buttons, or signs of water damage?
If you notice any significant damage, it’s best to consult a dealership or a qualified automotive locksmith to assess if the fob needs repair or replacement.

4. Consider Reprogramming
If you’ve ruled out the battery, interference, and physical damage, the issue might lie in the programming.
Important Note: Reprogramming your key fob often requires specific steps and might involve your Highlander’s security system. Refer to your owner’s manual for instructions or contact a Toyota dealership or qualified automotive locksmith for assistance.
