A dead key fob can be a major inconvenience, especially with a 2018 Toyota Highlander. This guide covers common causes, solutions, and how to regain access to your vehicle if your Toyota Highlander 2018 key fob is unresponsive, focusing on keyed entry and starting procedures. We’ll explore everything from simple battery replacements to more complex programming issues.
Understanding Your Highlander’s Keyless System
The 2018 Toyota Highlander’s keyless entry and start system is designed for convenience, allowing you to unlock and start your vehicle without inserting a physical key. However, when the key fob malfunctions, understanding the system’s backup procedures is crucial. This includes knowing how to use the physical key hidden within the fob for keyed entry and how to start the vehicle with a dead fob.
Common Causes of a Dead Toyota Highlander 2018 Key Fob
There are several reasons why your Toyota Highlander 2018 key fob might stop working. The most common culprit is a dead battery. Other possibilities include key fob damage, internal component failure, signal interference, or issues with the vehicle’s receiver. Identifying the root cause is the first step towards finding a solution.

How to Replace Your Key Fob Battery
Replacing the key fob battery is often the quickest and easiest fix. Most 2018 Toyota Highlanders use a CR2032 battery. You can usually find these at most stores. Locate the small release button on your key fob, often on the side. Press the button and separate the two halves of the fob to access the battery compartment. Carefully remove the old battery and insert the new one, ensuring the positive (+) side faces up. Reassemble the fob, and test its functionality.
Keyed Entry for Your Toyota Highlander 2018
Your Toyota Highlander 2018 key fob contains a hidden physical key. Locate the small release button or lever on the fob. Press it to release the emergency key. This key can be used to manually unlock the driver’s side door. Once inside, you can usually start the car by placing the key fob near the start button.

Starting Your Highlander with a Dead Fob
Even with a dead fob, you can usually start your 2018 Toyota Highlander. Locate the start button. With the brake pedal depressed, try placing the dead key fob directly against the start button. This may bypass the wireless signal and allow the vehicle to recognize the fob.
Troubleshooting Toyota Highlander 2018 Key Fob Issues
If replacing the battery and trying the keyed entry and start methods don’t work, there might be a more complex issue. Signal interference from electronic devices, a faulty key fob, or a problem with the vehicle’s receiver could be the cause.
