Audi A4 mechanical key door opening method: Insert the key into the driver's door lock cylinder and turn it counterclockwise to the unlock position. Below is an introduction to the Audi vehicle: 1. The Audi A4 has a length of 4858mm, width of 1847mm, height of 1439mm, and a wheelbase of 2908mm. It is equipped with a 7-speed dual-clutch transmission, a fuel tank capacity of 56L, and a top speed of 220 km/h. 2. The Audi A4 features a five-link independent suspension both in the front and rear, with a front-wheel-drive system. The tire specification is 225/50R17, and it comes with features such as brake force distribution, brake assist, front seatbelt reminder, cruise control, front and rear radar, and a rearview camera.
I remember the first time I used the Audi A4 key, it was incredibly simple. As you approach the car, the doors automatically unlock—just keep the key in your pocket or bag, get in, and sit in the driver's seat. The key point is to press the brake pedal; don’t slack off, or the engine won’t start—it’ll just power on. Then, locate the start button on the center console or near the steering wheel, press it, and the car will roar to life. The key is smart and senses everything without needing to be taken out. If the key runs out of battery, don’t panic—there’s a small switch on the key to extract the mechanical part. Open the door, and you can still start the car in the designated position with the sensing function. Pay attention to the key battery life regularly and replace it periodically for peace of mind. The overall design is very convenient and quick—keeping this habit makes driving hassle-free.
I usually enjoy tinkering with cars, and my Audi A4 starts via a keyless system. Just carry the key with you, sit in the car, press the brake pedal, and then press the start button near the dashboard. The sensor key can detect your presence nearby, whether it's in a bag or pocket. Once when the key battery was low, I used the mechanical part on the back to open the door, and the start was still managed via the induction slot inside the car. Remember not to place the key too far away or near metal objects that could interfere with the signal—keep it simple and don’t overcomplicate things.
