How to Disassemble a Wuling Hongguang Car Key?
2 Answers
On the side of the Wuling Hongguang key, we can see two slots inside. Use a screwdriver to gently pry open the slot area; some keys may require unscrewing. Once the battery cover is opened, the circuit board will be visible. After replacing the battery, reassemble it in the reverse order. Additional relevant information is as follows: 1. A remote key allows you to unlock and lock the door from a distance without inserting the key into the lock. Its greatest advantage is that, regardless of day or night, there's no need to locate the keyhole, eliminating the cumbersome process of inserting the key to open the door. It enables convenient remote locking (locking the door) and unlocking (opening the door). The remote key can also open the trunk and fuel filler cap from outside the vehicle, close the windows, and retract the side mirrors when locking the car. The key emits a weak radio wave from the owner's vicinity, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator (motor or electromagnetic coil) executes the lock/unlock action. This system mainly consists of a transmitter and a receiver. 2. During use, avoid exposing the smart remote key to strong magnetic fields, such as high-voltage power lines, transmission towers, or other areas with strong magnetic signals. Try to avoid parking the vehicle in such locations because the smart key uses low-intensity radio waves and may malfunction under magnetic interference. Additionally, avoid dropping or throwing the smart key frequently, as although most smart key casings are sturdy, repeated impacts can lead to poor battery contact inside.
I've taken apart the Wuling Hongguang's key before, and it's actually not that difficult but requires attention to detail. Use a small screwdriver or a plastic tool to gently pry open the gap on the side of the key—avoid using excessive force to prevent breaking the clips. Inside, you'll find a button battery, typically a CR2032. If the battery is low, replace it with a new one. Remember to handle it gently to avoid scratching the circuit board, as that could disable the remote function. Before reassembling, check that all buttons move smoothly and ensure all clips are securely fastened to prevent water or moisture ingress. Doing it yourself can save some money—I’ve replaced mine twice and found it quicker than going to a repair shop. The key is to work in a dry place to avoid dust getting in and affecting button responsiveness. After each disassembly, test the key to ensure it works properly and address any issues promptly.
