The reasons why the rear door of the Baojun 730 cannot be opened may include: 1. The child safety lock is engaged. Simply turn off the child safety lock function on the rear door to open it. 2. The door lock mechanism is damaged. Replacing it with a new one can solve the issue, or if the return spring on the lock mechanism has fallen off, removing the door panel and reinstalling the spring will fix it. 3. Check if the interior door handle is functioning normally. If pulling the handle feels unusually easy or lacks resistance, it may indicate that the handle is broken or the linkage between the handle and the lock mechanism has come loose. 4. If the interior door handle feels similar to normal use but the door still won't open, the linkage may have been stretched. This can happen if someone unfamiliar with the car forcefully pulled the handle without unlocking the central locking system. The linkage can be adjusted to fix this.
I've been driving my Baojun 730 for several years, and the rear door not opening is really common. The main reason might be the child lock being activated - that small switch on the side of the door prevents opening from inside when engaged, so check it regularly to prevent kids from messing with it. Also, locks tend to freeze in winter; spraying some de-icer or waiting for the car to warm up usually thaws it. Rust or dust buildup inside the lock mechanism can affect operation - I try spraying WD-40 for lubrication. If the door handle linkage comes loose or breaks, it usually requires a trip to the repair shop for adjustment; avoid forcing the handle to prevent worse damage. Electrical issues like blown fuses or aged wiring are beyond DIY fixes - better consult a professional technician. During routine maintenance, have mechanics inspect the locking system. Developing these small habits can prevent major troubles.
