Audi Q7 door cannot be locked due to: 1. Remote lock failure or factors such as aging of the car's remote transmitter antenna causing the remote key to be ineffective; 2. Strong magnetic field signal interference around the car. If the door is found not to lock, the spare mechanical key can be used to lock it. The Audi Q7 is a mid-to-large SUV that emphasizes comfort, with a body length, width, and height of 5069mm, 1968mm, and 1716mm respectively, and a wheelbase of 3001mm. The Audi Q7 is equipped with a four-wheel steering system. When steering at low speeds, the rear wheels turn in the opposite direction, reducing the turning radius and the width of the driving trajectory. At high speeds, the rear wheels turn in the same direction, improving wheel response speed, dynamic performance, and stability.
