Remote key active locking: Forgetting to lock the car after parking is a common occurrence, which can lead to the risk of theft of belongings inside the car, causing significant inconvenience and loss in daily life. Generally, when the key is removed, the power is turned off, and the doors are closed, the driver uses the remote key to actively lock the car. This is because most car models on the market do not have a key electronic signal distance detection function, so automatic locking cannot be performed by the car itself. Reminder function: The car will not automatically lock if you exit without locking it, but there is a reminder function that requires the remote key. If the car is unlocked with the remote key and no door is opened, the doors will automatically relock. The automatic locking scenario occurs when the car is unlocked with the remote key, and no door (including the trunk) is opened within one minute. In this case, the doors will automatically relock within one minute.
