What are the reasons for the failure to connect to the New Baojun Bluetooth key?
3 Answers
New Baojun Bluetooth key may fail to connect due to reasons such as Bluetooth being in an invisible state, excessive distance between Bluetooth devices, changed Bluetooth name, or hardware issues. Bluetooth invisible state: If the car Bluetooth or mobile phone Bluetooth is in an invisible state, neither party will be able to scan the other, making it impossible to perform connection and pairing operations. Excessive distance between Bluetooth devices: Since Bluetooth transmission has a certain distance limitation, when the mobile phone Bluetooth and car Bluetooth are too far apart, the Bluetooth device may not be detected. Even if detected, the excessive distance may affect the connection. Changed Bluetooth name: If the Bluetooth name is changed, the previously saved old Bluetooth name device will not be able to connect, but the new Bluetooth device name can still be searched for in other Bluetooth devices. Hardware issues: Although the possibility of hardware issues is relatively small, if none of the above assumptions are problematic, the possibility of hardware issues cannot be ruled out.
When my new Baojun Bluetooth key fails to connect, I've checked several times and found the most common issues are the phone's Bluetooth being turned off or incorrect permission settings. With rapid mobile system updates nowadays, app incompatibility can easily cause problems—make sure your app is the latest version. Signal interference is another factor; nearby Wi-Fi routers or large metal objects may weaken the connection. My habit is to first restart both the phone and the car, then try approaching the vehicle—sometimes it's just a distance issue or low key battery, which replacing the battery can fix. Additionally, accumulated app data cache might cause crashes, so clearing the cache or reinstalling the app is often effective. For safety, don’t rely solely on the Bluetooth key to unlock doors; always carry the mechanical key, especially when parking at night, just in case. It's advisable to regularly check for app updates to avoid connection failures affecting convenience.
After encountering Bluetooth key connection failures, I've explored several DIY solutions. First, ensure your phone supports Bluetooth 5.0 or above - the Baojun key has high device compatibility requirements, with different iOS/Android settings (check Bluetooth status in developer mode). Don't overlook signal interference; underground parking or electronics-dense areas significantly impact performance - try reconnecting at another location. The app is crucial - outdated versions or corrupted data cause errors; I manually clear cache or refresh the system. Low key battery frequently causes issues - replacing it's simple and cost-effective. For prevention, keep both app and phone OS updated, and avoid key connections during charging to prevent overheating. If problems persist, seek advice on car owner forums or use OBD tools to check vehicle Bluetooth module anomalies.
