As a Toyota Highlander owner, there’s nothing more frustrating than dealing with a dead key fob. Whether you’re running errands, heading to work, or embarking on a road trip, a non-functional key fob can bring your plans to a screeching halt. However, there’s no need to panic. In this article, we’ll explore the various methods to start your Toyota Highlander with a dead key fob, helping you get back on the road in no time.
Understanding the Key Fob System
Before we dive into the solutions, it’s essential to understand how the key fob system works in your Toyota Highlander. The key fob is a small device that uses radio frequencies to communicate with the vehicle’s computer system. When you press the button on the key fob, it sends a signal to the vehicle’s receiver, which then unlocks the doors, starts the engine, or performs other functions. However, if the key fob’s battery is dead, it cannot send the signal, leaving you stranded.
Situations that May Cause a Dead Key Fob
There are several situations that may lead to a dead key fob. Low battery levels are the most common cause, as the key fob’s battery can drain over time. Other factors, such as exposure to extreme temperatures, physical damage, or water damage, can also cause the key fob to malfunction. Additionally, interference from other devices or weak signal strength can disrupt the communication between the key fob and the vehicle’s computer system.
Methods to Start the Toyota Highlander with a Dead Key Fob
Fortunately, there are several methods to start your Toyota Highlander even with a dead key fob. Here are the most effective solutions:
Method 1: Using the Spare Key
If you have a spare key, you can use it to unlock the doors and start the engine. The spare key is usually provided with the vehicle and can be used in emergency situations. To use the spare key, simply insert it into the ignition and turn it to start the engine. Make sure to keep the spare key in a safe and accessible location to avoid any future inconvenience.
Method 2: Using the Hidden Key Compartment
Some Toyota Highlander models come with a hidden key compartment in the key fob. This compartment contains a small mechanical key that can be used to unlock the doors and start the engine. To access the hidden key compartment, you’ll need to remove the battery cover and slide out the mechanical key. Use the mechanical key to unlock the doors and start the engine.
Method 3: Using the Toyota Highlander’s Emergency Start Procedure
If you don’t have a spare key or access to the hidden key compartment, you can use the emergency start procedure to start the engine. This procedure involves pressing the brake pedal and holding the key fob close to the ignition. The vehicle’s computer system will recognize the key fob’s presence and allow the engine to start. However, this method may not work if the key fob’s battery is completely dead.
Prevention and Maintenance
To avoid dealing with a dead key fob in the future, it’s essential to maintain the key fob’s battery and keep it in good condition. Here are some tips to help you prevent a dead key fob:
Battery Maintenance
- Check the battery level regularly to ensure it’s not running low.
- Replace the battery every 2-3 years or as recommended by the manufacturer.
- Avoid exposing the key fob to extreme temperatures, as this can affect the battery’s performance.
Key Fob Maintenance
- Keep the key fob clean and dry to prevent water damage.
- Avoid physical damage to the key fob, as this can cause it to malfunction.
- Store the key fob in a safe location to prevent loss or theft.

What should I do if my Toyota Highlander’s key fob is dead and I’m locked out of my vehicle?
If your Toyota Highlander’s key fob is dead and you’re locked out of your vehicle, the first step is to remain calm and assess the situation. Check if you have a spare key fob or if someone else has a key that can unlock the vehicle. If you don’t have a spare key, you’ll need to seek alternative methods to gain access to your vehicle. You can try using the emergency door unlock procedure, which involves using the door handle to manually unlock the door. However, this method may not work for all Toyota Highlander models, so it’s essential to consult your owner’s manual for specific instructions.
To gain access to your vehicle using the emergency door unlock procedure, locate the door handle and look for a small notch or slot. Insert a thin object, such as a screwdriver or coat hanger, into the notch and gently pry the door open. Be careful not to damage the door or the surrounding area. Once you’ve gained access to your vehicle, you can try to start the engine using the ignition switch or look for the hidden key inside the key fob. If you’re still unable to start the engine or access your vehicle, it’s recommended to seek assistance from a professional locksmith or a Toyota dealership.
How do I start my Toyota Highlander with a dead key fob using the hidden key?
If your Toyota Highlander’s key fob is dead, you can try using the hidden key to start the engine. The hidden key is usually located inside the key fob and can be accessed by sliding open the key fob casing. To access the hidden key, locate the small notch or button on the key fob and press it to release the catch. Slide open the casing and pull out the hidden key. The hidden key is a normal key that can be inserted into the ignition switch to start the engine.
To start the engine using the hidden key, insert the key into the ignition switch and turn it clockwise to the “start” position. If the engine doesn’t start immediately, try wiggling the key back and forth while turning the ignition switch. This can help to ensure that the key is properly seated and the engine starts smoothly. Once the engine is started, you can use the vehicle as usual, but it’s recommended to replace the key fob battery or have it reprogrammed as soon as possible to avoid any future inconvenience.
Can I start my Toyota Highlander with a dead key fob using the push-button start feature?
If your Toyota Highlander is equipped with the push-button start feature, you can try using it to start the engine even if the key fob is dead. To use the push-button start feature, ensure that the key fob is inside the vehicle, usually in the center console or on the passenger seat. Locate the push-button start switch, usually located on the dashboard or center console, and press it to start the engine. If the engine doesn’t start immediately, try pressing the button again while ensuring that the key fob is in close proximity to the vehicle.
The push-button start feature uses a proximity sensor to detect the presence of the key fob, so it’s essential to ensure that the key fob is inside the vehicle and close to the sensor. If you’re still unable to start the engine using the push-button start feature, try moving the key fob closer to the sensor or checking if the key fob battery is completely dead. If the battery is dead, you may need to replace it or have it reprogrammed before using the push-button start feature. It’s also recommended to consult your owner’s manual for specific instructions on using the push-button start feature with a dead key fob.
How do I replace the battery in my Toyota Highlander’s key fob?
Replacing the battery in your Toyota Highlander’s key fob is a relatively simple process that can be done at home. To replace the battery, locate the small notch or button on the key fob and press it to release the catch. Slide open the casing and pull out the old battery. Take note of the battery type and orientation, usually indicated on the key fob or in the owner’s manual. Purchase a replacement battery that matches the specifications and insert it into the key fob, ensuring that it’s properly seated and oriented.
Once the new battery is inserted, slide the casing back into place and press the catch to secure it. Test the key fob to ensure that it’s working properly by locking and unlocking the vehicle. If the key fob still doesn’t work, try reprogramming it or seeking assistance from a professional locksmith or a Toyota dealership. It’s recommended to replace the battery in your key fob every 2-3 years or when you notice a decrease in performance, such as weak or intermittent signals.
Can I reprogram my Toyota Highlander’s key fob myself, or do I need to visit a dealership?
Reprogramming a Toyota Highlander’s key fob can be done by a professional locksmith or a Toyota dealership, but it’s also possible to do it yourself with the right tools and instructions. If you’re comfortable with DIY projects and have access to the necessary equipment, you can try reprogramming the key fob yourself. However, this method requires caution and attention to detail, as incorrect programming can render the key fob useless.
To reprogram the key fob yourself, you’ll need to purchase a key fob programming tool or software specifically designed for your Toyota Highlander’s model year. Follow the manufacturer’s instructions carefully, and ensure that you have the correct programming codes and procedures. If you’re unsure or encounter any issues during the programming process, it’s recommended to seek assistance from a professional locksmith or a Toyota dealership. They have the necessary expertise and equipment to reprogram the key fob quickly and correctly, ensuring that it works properly and securely.
What are the common causes of a dead key fob in a Toyota Highlander, and how can I prevent it from happening again?
The common causes of a dead key fob in a Toyota Highlander include a dead battery, water damage, physical damage, or software issues. To prevent a dead key fob from happening again, it’s essential to maintain the key fob properly, such as keeping it dry, avoiding physical stress, and replacing the battery regularly. You can also try to avoid exposing the key fob to extreme temperatures, magnetic fields, or other environmental factors that can affect its performance.
To extend the life of your key fob, try to keep it away from other electronic devices, such as smartphones or tablets, which can interfere with the key fob’s signal. You can also try using a key fob cover or case to protect it from physical damage and water ingress. Regularly checking the key fob’s battery level and replacing it when necessary can also help prevent a dead key fob. If you notice any issues with your key fob, such as weak or intermittent signals, try to address them promptly to avoid any inconvenience or security risks.
