How to Replace the Key Shell of Baojun 730?

First, pry open the back cover of the key with a tool. Then unscrew the three fixing screws. You can then open the battery compartment to replace the battery. After that, snap it back on and secure the screws.
Recently, the key shell of my Baojun 730 cracked, so I decided to replace it myself. The whole process was quite simple but required attention to detail. The first step was to gently pry open the old shell with a small screwdriver, being careful not to use too much force to avoid damaging the internal buttons or chip. The second step was to remove the battery and circuit board; I carefully pushed them out with my fingers to prevent the electronic components from falling off. The third step was to place the parts into the newly purchased matching shell, aligning the clips and pressing them in. The fourth step was to install the battery and test whether the buttons lit up normally and the locking function worked. After completion, the shell fit the car's design more aesthetically and provided waterproof and dustproof protection. I recommend buying an original shell online for about 50 yuan, which is half the price of going to a 4S shop. All you need are a Phillips screwdriver and patience, and the whole process takes about 15 minutes—very practical. Doing it myself also improved my minor repair skills, so I no longer worry about similar issues.
