How to Start a 2017 Toyota Highlander with a Dead Key Fob

Starting your 2017 Toyota Highlander with a dead key fob can be a frustrating experience. Whether you’re rushing to work or stranded miles from home, a dead key fob can put a serious damper on your plans. Thankfully, there are a few methods you can use to get your Highlander started and back on the road. This guide will walk you through several techniques, from simple solutions to more advanced options, ensuring you’re never left stranded by a dead key fob again.

Understanding Your 2017 Toyota Highlander Key Fob

Before we dive into the solutions, it’s important to understand a little about how your key fob works. The 2017 Highlander typically uses a smart key system, meaning the key fob communicates wirelessly with your vehicle. This allows for keyless entry and push-button start. However, this technology relies on a battery within the key fob, and when that battery dies, it can seem like you’re locked out of your own car. Don’t panic! There are workarounds.

Simple Solutions for a Dead Key Fob

Often, the simplest solution is the best. Check these first before moving on to more complex procedures.

Replace the Battery: This seems obvious, but it’s often overlooked. If you have a spare battery on hand, replacing it is the quickest and easiest fix. Most key fobs use a standard CR2032 battery, which is readily available at most stores.
Try the Spare Key Fob: If you have a spare key fob, try using that to start the car. This can help confirm whether the issue lies with your primary key fob or something else entirely.

Starting Your Highlander With a Dead Key Fob Battery

Even if your key fob battery is completely dead, your Highlander is still equipped with features to allow you to start the vehicle.

Using the Hidden Key: Most smart key fobs have a hidden mechanical key inside. This key can be used to unlock the driver’s side door manually. Once inside, look for a designated spot, usually near the steering column or inside the glove box, where you can place the key fob. This allows the car to detect the fob’s transponder even if the battery is dead, enabling you to start the engine using the push-button start.
Jumpstarting the Key Fob (In Some Cases): While not always possible, some key fobs allow for a temporary jumpstart by touching them to the start button. Refer to your owner’s manual to see if this method applies to your Highlander model.

Advanced Troubleshooting

If none of the above methods work, it’s possible there’s a different issue at play.

Check the Car Battery: A dead car battery can mimic the symptoms of a dead key fob. Try jumpstarting your Highlander to rule out this possibility.
Check the Key Fob’s Transponder: The key fob’s transponder, the component responsible for communicating with your vehicle, could be malfunctioning. This requires professional diagnosis and potentially a replacement key fob.

Preventing Future Key Fob Issues

Here are a few tips to avoid being stranded by a dead key fob in the future:

Regularly Check Your Key Fob Battery: Just like your car battery, your key fob battery has a limited lifespan. Replace it proactively every year or two.
Keep a Spare Key Fob: Having a spare, fully functional key fob is essential. Make sure its battery is also fresh.

Dealing with a dead key fob can be a hassle, but knowing how to start your 2017 Toyota Highlander with a dead key fob empowers you to overcome this challenge. By following the steps outlined in this guide, you can get your Highlander back on the road quickly and efficiently. Regular maintenance and having a spare key are crucial for preventing future issues.
