How to Fix the Malfunctioning Remote Key of Baojun 730?
2 Answers
If the remote key of Baojun 730 is unresponsive, it is recommended that the owner replace the battery. The battery life of a remote key is generally 2-3 years, and replacing the battery when it runs out of power should resolve the issue. Here is some related information about remote keys: 1. Introduction: A remote key utilizes the wireless remote control function of the central locking system, allowing the user to unlock or lock the doors from a distance without inserting the key into the lock. 2. Working Principle: The key first emits a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator (either a motor or an electromagnetic coil) performs the locking or unlocking action.
I think the remote key failure of the Baojun 730 is quite common. I've driven this car for several years and encountered it a few times. The most frequent issue is usually a dead battery—the CR2032 button cell runs out easily, and replacing it yourself only costs a few bucks. First, check if the key's indicator light is on. If it doesn't flash, try replacing the battery. If that doesn't work, the internal circuitry might be damaged or the antenna could have poor contact—you can open it to inspect but avoid tampering carelessly. Sometimes, signal interference is the culprit, like having a phone or metal objects in the key pouch—just move them away. For deeper issues like a faulty vehicle receiver or lost programming, you'll need to visit a 4S shop or a professional repair center to reset it with a diagnostic tool. To minimize failure risks, avoid exposing the key to moisture or drops, and clean the contacts regularly.
