Can the car be locked if one door is not properly closed?

[StEloise]

A situation where one door is not properly closed: the car cannot be locked. Below are detailed explanations and solutions for the reasons why the door cannot be locked: 1. Lubrication effect: If a single door cannot be locked, you can try opening and closing the door again before attempting to lock it. This may be due to a weakened lubrication effect in the locking mechanism. Solution: Spray some lubricant to lubricate it. 2. Self-fault: If the car's remote lock cannot lock the door, it is generally due to a fault in the remote key itself, such as aging of the car's remote transmitter antenna causing it to not receive the signal from the car's remote key, or strong magnetic field interference around the car, which also prevents the remote key from being used. Solution: You should go to a repair shop or a 4S shop as soon as possible for a detailed inspection to avoid unnecessary losses.
