What is the reason why the Sagitar remote control cannot control the windows with one key?

The reasons why the Sagitar remote control cannot control the windows with one key are: 1. The car window regulator is malfunctioning; 2. The remote control battery is dead. Taking the 2021 Sagitar as an example, it belongs to the compact car category, with body dimensions of: length 4753mm, width 1800mm, height 1462mm, wheelbase of 2731mm, and a fuel tank capacity of 50l. The 2021 Sagitar has a front suspension of MacPherson independent suspension and a rear suspension of multi-link independent suspension. It is equipped with a 1.2l turbocharged engine, with a maximum horsepower of 112ps, maximum power of 85kw, maximum torque of 175nm, and is paired with a 5-speed manual transmission.

I've been driving my Sagitar for a while and have also encountered the issue where the remote control can't operate the one-touch window function. The most common reason is when the key battery is running low, causing the signal to weaken and malfunction. Another possibility is when the car isn't turned off or the door isn't properly closed, as the system will restrict the remote function. Additionally, initialization loss might occur, possibly due to disconnecting the battery cables, requiring a reconfiguration. I've personally tried holding the window switch up and down to the end to reset it. If these methods don't work, it could be due to circuit interference or a blown fuse. Don't delay getting it checked—safety first. Regularly avoid getting the key wet or dropping it frequently to extend battery life. On forums, I've seen many people overlook initialization, which can often be fixed with a simple procedure. If the problem persists frequently, consider unstable battery voltage or a faulty remote itself, and visit a professional shop for inspection.

I enjoy tinkering with cars and have encountered remote control failure several times. First, check if the key battery is drained and try replacing it with a new one—it's cheap and simple. If that doesn't work, inspect the window initialization: sit in the car with the door closed, start the engine, press and hold the window switch on the driver's door to raise the window to the top for a few seconds, then lower it to the bottom for a few seconds to reset the program. If it still doesn't work, it might be a blown fuse—check the corresponding fuse for the headlights or windows in the fuse box under the steering wheel and see if it's burnt black. Sometimes, loose wiring connections or short circuits due to moisture can be the issue; you can use a multimeter to test the voltage and locate the problem. If these DIY methods don't help, it's likely a control module failure—don't force it and take it to a shop for repair. Remember to test the battery during regular maintenance, as low voltage can cause malfunctions.

The remote control isn't working. I've seen this many times over decades of driving. It's usually due to low battery power in the key, preventing signal transmission—just replace the battery. Alternatively, the remote might be damaged, such as from being dropped or exposed to water. Initialization errors are also common, caused by power interruptions or software glitches, and can be resolved with a reset. Don't take it lightly; if there's an issue, avoid using the remote to open windows—manual operation is safer. An aging battery causing unstable power supply can also affect the remote, so ensure the vehicle is stationary and check it.
