How to Activate One-Touch Window Roll-Up with Key for Buick Excelle?

[Robyn]

You need to visit a 4S shop to refresh the vehicle's program. After refreshing, press and hold the lock button on the key for a few seconds to roll up the windows. However, for models without this hidden feature, you will need to install a window lift module to achieve one-touch window roll-up with the key. One-touch window roll-up refers to a system where the window glass can be controlled to roll up or down with a single press of a button. It can be controlled either through the window button or via the smart key's switch. Currently, mid-to-high-end models are equipped with the one-touch window roll-up feature, which effectively enhances convenience and safety. More details are as follows: 1. One-touch window roll-up with smart key: The working principle involves the key emitting radio waves, which are then executed by the system's actuator to perform the roll-up or roll-down action. Press and hold the unlock button on the key to automatically lower all four windows, and press and hold the lock button to automatically raise all four windows. 2. Window button control: Briefly press the window button to automatically lower the window completely. If you press and hold the button, releasing it will stop the window from descending further. Briefly lift the window button to automatically raise the window completely. If you lift and hold the button, releasing it during the ascent will stop the window from rising further.
