Common Reasons for a Dead Key Fob
Let’s explore some of the most frequent culprits behind a non-responsive key fob:
1. Dead Key Fob Battery
The most common reason for a dead key fob is a dead battery. Over time, the battery that powers your key fob will drain and eventually die. Fortunately, replacing the battery is a quick and easy fix.
How to Check and Replace the Battery:
- Locate the battery compartment on your key fob. This is usually on the back or side and can be opened with a small screwdriver or coin.
- Carefully remove the old battery and note its type (usually CR2032 or similar).
- Insert a new battery of the same type, ensuring it’s facing the correct direction.
- Close the battery compartment.
After replacing the battery, try using your key fob again. If it still doesn’t work, there might be another issue.

2. Key Fob Programming Issues
Sometimes, the issue isn’t a dead battery, but rather a problem with the key fob’s programming. This can happen after a battery replacement or due to electronic glitches.
Possible Solutions:
- Try Reprogramming the Key Fob: You can often find instructions for reprogramming your specific Highlander model in your owner’s manual. Some models require a specific sequence of button presses, while others need to be programmed by a dealership or locksmith.
- Check for Interference: Electronic devices, like cell phones or Bluetooth devices, can sometimes interfere with key fob signals. Move away from any potential sources of interference and try again.

A damaged key fob is less likely to be the culprit, but it’s worth inspecting your key fob for any physical damage.
What to Look For:
- Cracks or Breaks: Inspect the key fob casing for any visible cracks or breaks.
- Water Damage: If your key fob was exposed to water, it could be damaged. Look for any signs of corrosion or moisture inside the battery compartment.
- Worn Buttons: If the buttons on your key fob are worn out, they may not be making proper contact.
If you notice any significant damage, you’ll likely need to replace your key fob.
This part focuses on physical damage as a potential cause, making it relatable with scenarios like water exposure and worn-out buttons.
4. Faulty Car Battery or Electrical Problems
While less common, a weak or dead car battery can sometimes prevent the key fob from working correctly.
Troubleshooting Tips:
- Test Your Car Battery: Use a voltmeter to check the voltage of your car battery. A healthy battery should read around 12.6 volts. If it’s significantly lower, your battery may need to be charged or replaced.
- Check for Other Electrical Issues: Issues with your car’s electrical system, such as a blown fuse, can also affect the key fob’s functionality.
