Does the Audi A3 have a one-button start?

[LeSebastian]

Audi A3's one-button start is an optional feature; some models have it, while others don't. The optional smart key includes the one-button start and keyless entry functions. Here is some relevant information: 1. The one-button start button can only be installed in the original keyhole position of the Audi A3, meaning the original keyhole is replaced with a start button. This doesn't significantly enhance the vehicle's interior aesthetics, and it's hardly noticeable to others. 2. Most modifications for one-button start require bypassing the Audi A3's steering wheel lock. The bypass method involves inserting the original key into the keyhole, turning it to the 'on' position, breaking the key so that the broken part remains in the keyhole, and then attaching the start button directly over the keyhole. 3. If the smart key's battery is low or the smart key malfunctions, the battery should be replaced promptly. If the vehicle needs to be used, the door can be opened with the mechanical key, and the engine can be started by inserting the smart key into the smart key lock cylinder.
