Why can't the Sagitar's windows be opened by long-pressing the key?
4 Answers
Sagitar's windows cannot be opened by long-pressing the key due to the failure of the one-touch window lift function, which requires reinitialization. It is necessary to contact a 4S shop. Here is the extended content: 1. How the one-touch lift key works: The key emits a weak electric wave, which is received by the car's antenna. The electronic control unit identifies the signal code, and then the system's actuator performs the action of opening or closing the lock. 2. Long-pressing the unlock button on the remote control will automatically lower all four windows, while long-pressing the lock button will automatically raise all four windows. 3. Whether controlled by a smart key or a mechanical button, the one-touch window lift generally has an anti-pinch function. During the automatic closing operation, if an object is caught between the glass and the window frame, the window's closing operation will automatically stop midway and return to its initial state to prevent the risk of pinching.
I also encountered this issue with my previous Sagitar. The inability to open windows by long-pressing the key is usually caused by several common reasons. Insufficient battery power is the most common one – the coin cell in the remote key weakens over time, leading to unstable signals and failure to activate the window function. System setting reset is another factor. Sometimes the car's computer needs to re-pair the key. I've tried doing it myself: sit in the car with the windows closed, press and hold the unlock button on the key for a few seconds to restore the settings. Check if the key itself is damaged, such as being dropped or exposed to water, as internal circuit issues can affect the signal. There's also a possibility of a fault in the vehicle's power system, like unstable output voltage from the alternator interfering with electronic functions. I recommend first trying a new battery. If that doesn't work, visit a 4S shop to read the fault codes. Don't delay, as this feature is very practical for daily parking and cooling, helping to avoid overheating inside the car and ensuring comfort. Regularly keep the key dry and clean, and check the battery status periodically to extend its lifespan and reduce trouble.
When I first got my Sagitar, I also found it strange that the windows wouldn't open by long-pressing the key. The reasons are usually not complicated. First, the function might not be activated and requires manual initialization: get in the car, turn on the ignition without starting the engine, close all windows, then press and hold the unlock button on the key for more than 5 seconds until you hear a beep, indicating success. Second, the key battery might be dead—replacing it costs just a couple of dollars and can be done yourself by unscrewing the small cover on the back of the key. Another possibility is a vehicle setting restriction; this feature might be disabled in the dashboard menu, so check the manual or adjust the settings. Lastly, it could be a hardware issue like a stuck window motor or a burnt circuit, though this is rare. A simple solution is to replace the battery and reset the system, which usually fixes the issue—no need to panic or waste money at a repair shop. Regular users can handle this easily. To prevent unnecessary battery drain, keep the key away from high temperatures and humid environments.
From a maintenance perspective, the reasons for the failure of the Sagitar's remote-controlled windows involve the electronic control system. The remote signal not being recognized by the body module could be due to aging of the key transmitter or internal chip failure; system settings may require reprogramming, such as pressing the lock button several times to reset; poor contact in the window controller module or a blown fuse could also be the cause; another possibility is a CAN bus communication interruption, preventing the command from being transmitted. As an experienced automotive professional, I recommend checking the key's voltage with a multimeter—it should normally be above 3 volts; otherwise, visit a professional shop to scan the ECU for fault codes such as B1347. Long-term neglect can lead to window jamming, affecting usability. Prioritize simple troubleshooting before seeking technical support.
