What is the reason for the Baojun 730 door lock malfunction?
2 Answers
Baojun 730 door lock malfunction is caused by issues with the central control motor. Most car door locks nowadays use smart door locks, also known as keyless entry systems, which are electric opening systems installed on the side doors of vehicles. Here is relevant information about car door locks: Electronic Door Locks: These use programmable memory and data reading devices, making their keys difficult to duplicate. The key contains a 3.5×3.5mm dedicated electronic chip that stores a specific password. When the key is inserted into the lock, the password is sent to the memory in the lock, generating a magnetic field and producing voltage in the coil on the chip, which serves as the power source for unlocking. If the password in the key matches that of the lock, the lock opens. Mechanical Door Locks: A six-digit password lock can have over 3.25 million password combinations for the owner to change at will, offering extremely high security. Optional password groups are arranged consecutively, providing convenience for selecting easy-to-remember passwords. Currently developed basic models allow the number of password digits and the password capacity to be redesigned according to user needs. An alarm interface can also be added for users.
I've handled many owner issues with the Baojun 730 before, and there are several common causes for locking failures. The most easily resolved is a depleted remote key battery—simply replace it with a new one and try again. Signal interference is also frequent, such as when parked near a signal tower or with metal objects blocking the key signal; moving the car or adjusting the angle of operation can help. A damaged door lock motor is quite common, where you hear the unlocking sound but the door doesn't move. In this case, check the fuse box for the 10A fuse labeled for the door lock and replace it if blown. Loose or corroded wiring connections, especially worsening after rainy days, require removing the door panel to inspect and tighten the plugs. For safety, don't delay—get it checked at a proper service center as soon as possible to avoid mid-journey failures affecting your trip.
