Opening a Lexus with a Dead Key Fob: A Comprehensive Guide

Introduction

If you own a 2016 IS350 F Sport, you might have encountered the challenge of opening your car with a 'dead' key fob. Thankfully, the car's original key fob contains an actual key inside, which can be used in a traditional manner to unlock your vehicle. This article provides a detailed guide on how to open your Lexus using this method, ensuring your car stays accessible even in a 'dead' key fob scenario.

Understanding the Key Fob

Lexus vehicles, especially models like the 2016 IS350 F Sport, come equipped with advanced keyless entry systems. However, these systems may malfunction or become 'dead,' preventing you from using the remote to unlock your car. In such situations, you can still access your vehicle through a clever workaround using the key fob.

Locating the Hidden Key

The key fob used with your Lexus is not just a remote control. It contains an actual key, which is designed to fit into the ignition. This hidden key can be used in emergency situations to unlock your car.

Key Positioning

The key is positioned on the opposite end of the key fob from the buttons. When using the fob, your thumb should be placed on the button you wish to press, while the key is on the other side of the fob. This design ensures you can still access your vehicle even if the keyless entry system is dead.

Steps to Unlock Your Car

Follow these steps to unlock your Lexus when the key fob is dead:

Verify the Key Fob: Hold the key fob in your hand to ensure it is not merely showing signs of electrical failure but truly lacks functionality. If the key fob has no power, the battery may be dead, or the circuitry could be damaged. Identify the Hidden Key: As mentioned, the key is located on the opposite end of the key fob from the standard buttons. If you can see a small keyhole cutout on the fob, that's where the key is hidden. Insert the Key: Carefully extract the key from the key fob and insert it into your car's ignition. With some older models, you might need to pull the key fob gently to dislodge the key. Start Your Car: Once the key is inserted, you can start your IS350 F Sport or any other model with a similar setup.

Preventive Measures

While this method can be a lifesaver, it is always better to prevent such situations from arising in the first place:

Battery Troubleshooting: If you frequently encounter dead key fobs, check the battery. Dead key fobs may be a sign of a low battery, which can be replaced to prevent future issues. Professional Service: Contact your dealership or a professional mechanic to diagnose and repair any underlying electrical issues with your keyless entry system. Regular Maintenance: Regularly inspect and maintain your key fobs to ensure they remain functional.

Conclusion

With a little bit of knowledge and the hidden key inside your Lexus key fob, you can still access your vehicle when faced with a dead key fob. Understanding the design of your key fob and knowing how to extract the key ensures you can maintain control over your car at all times, even in emergency situations. Whether you own a 2016 IS350 F Sport or any other Lexus, this guide will help you navigate potential key fob malfunctions with ease.
