In this article, we’ll explore a quick trick to start your car when faced with the Key Not Detected warning, ensuring you can get back on the road swiftly.

Locating the Start Stop Button:

The first step is to locate the engine’s Start Stop button in your car. Typically found on the dashboard near the steering column or center console, this button is the focal point for our workaround.

The Simple Trick:

Retrieve Your Key Fob

Take your key fob—the device responsible for transmitting signals to your car’s ignition system. Ensure it’s in your possession and ready for use.

Proximity to the Start Stop Button

Place the key fob as close as possible to the Start Stop button. This step is crucial for the workaround to be effective.

Press the Brake Pedal

Before attempting to start the engine, press the brake pedal. This is a standard safety procedure in most modern cars and ensures that the vehicle is in a safe state for ignition.

Press the Start Stop Button

With the key fob in close proximity and the brake pedal depressed, press the Start Stop button as you normally would when starting your car.

Success! In many cases, your engine should come to life, even with the persistent Key Not Detected warning on your dashboard. You’re now back in business, and you can continue your journey without further delays.

Important Note:

While this trick provides a quick and temporary solution to the Key Not Detected issue, it’s crucial to address the root cause. As soon as possible, replace the battery in your key fob. A dead or low battery is often the culprit behind this warning, and replacing it ensures reliable long-term use and peace of mind.
