Baojun 730 IMMO mismatch occurs because the vehicle's anti-theft system has entered the anti-theft mode. IMMO stands for the anti-theft system. This fault happens when the key chip does not match the system, causing the system to lock. The specific steps to resolve the issue are as follows: Press the one-touch start button: Press the vehicle's one-touch start button to turn on the power.

Last time I helped a friend fix his Baojun 730, there were quite a few reasons for the IMMO system mismatch. The most common issue is with the key chip—like when the key gets dropped and damages the internal electronics, or the battery is too low to send out a signal. Another major problem is a fault in the anti-theft control unit, which can happen if the car battery dies and resets the system, or if there's a software bug that wasn't updated in time. Also, if the car's wiring was previously modified, like adding a new sound system, improper connections might interfere with signal transmission. Errors often occur during key programming, especially when replacing a new key—many people skip the re-matching step to save time. If you encounter this issue, I recommend first trying the spare key. If that doesn't work, check the car battery voltage; if it's too low, try charging it. If the problem persists, take it to a professional shop to diagnose the trouble codes with proper tools to avoid dangerous breakdowns on the road. Regular maintenance can prevent these issues in advance.
