What are the reasons for Volkswagen key window lift failure?

[VonHector]

Volkswagen key window lift failure can be caused by damage to the key's transmitter, damage to the car's receiver, damage to the door lock, or a dead battery in the key. Below are the solutions for key window lift failure: Manual lift: Manually raise the window to the top, then hold the lift button to keep the motor in a stalled state for 3 seconds. At this point, the anti-pinch motor will restart the automatic lift and anti-pinch function. Manual lower: Manually lower the window from the top to the bottom, then hold the lower button to keep the motor in a stalled state for 3 seconds. The anti-pinch motor will record the lower stop point after detecting the lowering speed, and the soft stop function for lowering will be activated.
