1 Answers
Press and hold the lock button for 5 seconds without releasing to simultaneously raise all windows for closing. Similarly, press and hold the unlock button for 5 seconds without releasing to simultaneously lower all windows for opening. Relevant details are as follows: 1. Programming Update: Not all car remote keys can control simultaneous window operation. Generally, Volkswagen group vehicles may have this hidden feature, but it requires visiting a dealership to have technicians refresh the vehicle's software first. This function becomes available after programming as long as the original system includes remote key and central locking capabilities. 2. Aftermarket Installation: For vehicles without this hidden feature, owners who want one-touch window control via remote key need to install an additional window control module. Owners may visit aftermarket modification shops or dealerships to have technicians install this module.
