Does the Audi A3 have a one-button start?
1 Answers
Audi A3 models do not come standard with a one-button start; it is an optional feature. The optional smart key includes both the one-button start and keyless entry functions. The one-button start button can only be installed in the original keyhole position of the Audi A3, meaning the original keyhole is replaced by a start button. The method to use the one-button start is as follows: First, press the start button once to turn on the ACC light, then press the start button again. At this point, the one-button start button turns green, and the vehicle begins self-inspection. After the vehicle completes the self-inspection, press the brake and press the one-button start button once more to start the vehicle. The benefits of the one-button start include: No need for the original car key or remote to open the door; automatic window closing when leaving the car; convenient starting; and built-in anti-theft functionality. The working principle of the one-button start is based on radio frequency identification (RFID) technology. The smart card's chip automatically senses and controls the door locks. When the owner approaches the vehicle, the system automatically recognizes the owner's identity, unlocks the doors, and disables the anti-theft system without requiring the use of a key.
