Will the Car Door Lock Automatically If Not Locked?

[LeLucia]

No. Below is relevant information: How a car works: When the key is removed to cut off the power and the car door is closed, it is generally the driver who actively locks the car using the remote key. The reason is that most models on the market do not have the function of detecting the distance of the key's electronic signal. Additional information: Precautions: 1. Try to use the mechanical key to lock the car: When locking the car, it is still advisable to use the mechanical key, as this makes any signal jammer ineffective. If you don't mind the inconvenience, using the mechanical key more often can also save power and is safer than using a smart key. When using the mechanical lock, make sure the car door is properly closed and you hear the sound of the entire car locking; otherwise, it means the car was not successfully locked. 2. Try to park in a guarded parking lot and ask for a parking receipt: When parking for a long time, choose a guarded parking lot and ask for a parking receipt. This way, if any issues arise with the vehicle, you can ensure no loss occurs. However, you should still lock the car doors. Generally, in formal parking lots, criminals are less likely to enter.
