What are the reasons why the Peugeot car door cannot be locked?

[StElias]

The reasons why the Peugeot car door cannot be locked are as follows: 1. Check whether the lock actuator is functioning: If there is no action, it is likely that the central control system wiring has poor contact. 2. If the lock actuator is functioning: it may be due to high resistance in the locking mechanism, usually caused by rust. 3. It could be that the position of the door lock motor latch has shifted: a slight adjustment is all that is needed. 4. The door lock motor is broken or the pulling force is insufficient: in this case, the motor needs to be replaced. Additional information: A good car door will have at least two anti-collision beams, which are relatively heavy, but heavier doors are not necessarily better. In modern cars, as long as safety performance and other factors are ensured, designers will try to reduce the weight of the vehicle, including the doors (such as by using new materials), to reduce power consumption. Based on the number of doors, cars can be classified into two-door, three-door, four-door, five-door models, etc. Cars used for official purposes are mostly four-door, while those for family use can be four-door, three-door, or five-door (with a lift-up rear door). Sports cars are mostly two-door models.
