[MacVera]

Method to set one-touch window roll-up in a car: Pull the window button directly to raise the window to the top, then hold for 3 to 5 seconds without releasing your finger. Next, press the window button to lower the window completely, again holding for 3 to 5 seconds before releasing. Then test the one-touch function to confirm the setup is complete. Working principle of one-touch window roll-up: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit identifies the signal code, and the system's motor or electromagnetic coil executes the opening/closing action. Press and hold the unlock button on the remote to automatically lower all four windows; press and hold the lock button to automatically raise all four windows.
