The Mistra does not support one-touch window closing with the remote key. If you need this feature, you will have to install some additional devices to achieve it. Hidden functions of the Mistra key: 1. Vehicle locator: There is a button on the remote with a horn symbol. Pressing it will make the car alarm sound, with an effective range of over 40 meters. 2. One-touch window closing: Press and hold the lock button on the remote, and the windows will automatically close. 3. Automatic trunk opening: Press and hold the trunk switch lock button or press it twice in succession, and the trunk will open automatically. 4. One-touch window opening: Press and hold the unlock button to achieve this.

I've driven the Mistra for several years and found that most newer models support the key-controlled window closing feature. My car is a 2018 model, where simply pressing and holding the lock button on the remote key for three to five seconds will gradually raise and close all windows. This function is particularly useful during rainy days or when you forget to close the windows before leaving. However, older models may not have this feature as standard, such as the lower-spec versions before 2014. You might need to check the vehicle manual or visit a 4S store to upgrade the module. If it doesn't work, first check if the key battery is dead or if the system has disabled the function to avoid window jamming or accidental opening/closing issues. Regular maintenance, like keeping the window tracks clean, can also make the operation smoother.

As someone who often helps friends with car repairs, I know quite a bit about the key-controlled window closing feature of the Mistra. Generally, high-end Mistra models from 2015 onwards come with a built-in one-touch window closing system. Just hold the lock button for a few seconds to close all windows. However, make sure the operating distance isn't too far; within about five meters is safest. If it doesn't work, it could be due to a short circuit in the wiring, a blown fuse, or a faulty body control module. Trying to disassemble and inspect it yourself can easily lead to mistakes, so it's recommended to take the key to a professional shop for scanning and diagnosis. The base model Mistra lacks this feature, but adding a remote module is relatively inexpensive and can also enhance anti-theft protection. In daily use, avoid forcing the operation when the vehicle is running or the windows are partially open to prevent motor overheating and damage.

I often use the key to close the windows when commuting with my Mistra. By holding the lock button for about three seconds, the windows close automatically, which is both convenient and effortless. Not all Mistra models have this feature; it's generally supported in newer versions, while older ones may not. Remember to wait until the windows are completely closed before releasing the button to prevent them from stopping midway. If there's no response, check if the key needs a battery replacement or if there's any signal interference near the car affecting the transmission. It's a simple and quick function, perfect for situations when you forget to close the windows.
