Why is the Lavida's one-button start not sensitive?

[MacHector]

Lavida's one-button start button is not sensitive for the following reasons: Key is too far away: The one-button start relies on key sensing, and the car cannot start if the key is too far away. Not pressing the brake when starting: If you press the one-button start without pressing the brake, the car will power on, but the engine will not start. Not pressing long enough: If the button is not held long enough or not pressed all the way down; or if the gear is not in the P position. Smart key battery is dead: If the smart key battery is dead, open the car door and place the smart key in the storage box behind the handbrake, then you can start the car with one button. The Lavida is an independently developed A-class car by Shanghai Volkswagen.
