What are the reasons why BMW's one-button start fails to ignite?

[LaKimberly]

Specific reasons why BMW's one-button start fails to ignite: 1. Steering wheel lock: The steering wheel lock is an anti-theft feature. When the car is turned off, rotating the steering wheel a certain angle from its centered position in one direction will lock it. In this state, the one-button start function won't work. To release the tension and unlock the steering wheel, turn the steering wheel left and right while pressing the engine start button. 2. Gear not in P position: This can also prevent the one-button start from igniting the engine. 3. Smart key battery dead: When the vehicle's smart key battery is dead, the key's transmission power is low, making it difficult for the car's sensors to detect it, thus preventing the one-button start from completing the ignition.
