Audi A4 does not have a keyhole; it is equipped with a one-button start system. Introduction to one-button start: The one-button start device is part of a smart car, a button device that simplifies the starting process and can also turn off the engine. This device can be retrofitted in the original key lock position or installed as an independent panel. Functions of one-button start: Unlike traditional mechanical key ignition methods and conventional starting procedures, simply pressing the one-button start button can start or turn off the engine, eliminating the hassle of losing or searching for keys. During the ignition process, most require pressing the foot brake.

Having driven an Audi A4 for over a decade, I know these details like the back of my hand. The key slot is usually located just below the right side of the steering wheel, near the instrument panel – you can spot it with a slight glance downward. In older models like the 2010 version, it's a clearly visible slot where inserting the key starts the engine. For newer keyless start models, such as post-2018 versions, the hidden slot might only be used in emergencies, still positioned around the right-hand drive area. I've always found this design clever – convenient for operation while driving without causing distraction. I remember finding it very intuitive when I first drove the car. It's good practice to regularly check the slot's location to avoid fumbling in the dark. Ultimately, frequent use will make you remember it naturally.

I remember being confused about where the keyhole was when I first bought my Audi A4. Later, I found it on the right side of the steering wheel, near the air vent—just insert the key to start the car. For newer models like the 2020 version, it might be integrated into the keyless start system, with a small backup slot on the center console. I recommend checking the owner's manual for a location diagram or taking your time to feel around the interior in good lighting. Don’t worry—after a few tries, it’ll become second nature. This is crucial for daily convenience, especially as an emergency backup if the remote battery dies. The location hasn’t changed much over the years, maintaining a similar setup from older to newer models for safety and practicality. With practice, everything becomes simpler.

As someone who frequently deals with vehicle issues, I'm very familiar with the keyhole position of the Audi A4. It's usually located below the right side of the steering column, with the hole directly exposed. For keyless models, the keyhole might be hidden under the dashboard, requiring a button press to start, and is only used for emergencies. The design prioritizes accessibility, minimizing the need to bend or exert effort. In practice, the keyhole sees little wear due to infrequent use, but knowing its location prevents delays during malfunctions. Integrated with the car's layout, it's conveniently near the driver's seat, ensuring a smooth starting process. Remembering this helps avoid misoperations that could lock the system. Overall, it offers high practicality.
