Where is the keyhole for the one-button start?

The keyhole for the one-button start is located behind the one-button start button. You can see it by prying off the plastic one-button start button. The method to use the one-button start is: 1. Open the car door and get in; 2. Press the brake; 3. Press the start button to complete the one-button start. The working principle of the one-button start is: radio frequency identification technology, which automatically locks and unlocks the doors through the chip in the smart card. When the owner approaches the vehicle, the vehicle automatically recognizes the owner's identity, and the door locks will automatically open and deactivate the anti-theft system without using a key. The method to install a one-button start is: turn the mechanical key to the "no" position, ensuring the entire vehicle is powered on. The wire on the original ignition switch that has no power is the starter motor wire, which should be connected to the starter motor wire of the one-button start.
I recently bought a new car with a one-button start feature, and this is actually a great question because many people get confused when they first encounter it. The button is usually located on the driver's side of the center console area, either next to the steering wheel or on the side of the gear shift, and you can easily spot the START label—press it to start the engine. Traditional keyholes have mostly disappeared in modern cars like this, relying entirely on a keyless system. You just need to keep the key fob on you, and the car will sense it to start. If the button doesn’t respond when pressed, it might be due to a dead key fob battery. In some models, there’s a hidden small cover below the button—prying it open reveals a backup keyhole where you can use the mechanical key as an emergency workaround. I’ve experienced this in a friend’s car; the location varies by model, such as behind the steering column or under the center armrest. For beginners, I recommend checking the user manual to familiarize yourself with the design and avoid mishaps that could delay your drive.
