What to Do When the BAIC Huansu H2 One-Key Start Doesn't Respond?
2 Answers
If the one-key start doesn't respond, it may be due to the vehicle key being out of battery or nearly depleted. Check if the key has power, and if not, replace the battery. Another possible reason for the one-key start not responding is interference with the key's radio waves. Inspect the vehicle interior for any sources of interference and remove them as soon as possible. When the steering wheel is locked, the one-key start function will also not work. Check if the steering wheel is in a locked state and release the steering wheel lock. Additionally, inspect the throttle, fuel injector, spark plugs, ignition wires, and ignition coil.
When I first encountered the issue with the BAIC Huansu H2's one-button start not responding, I initially thought the button was faulty. However, I later conducted a self-check at home. First, test if the key fob battery is dead—you can try starting with the spare key or replace it with a new battery. Next, check the car battery voltage using a multimeter; if it's below 12V, it might be out of power. Then, inspect the relevant fuses in the fuse box to see if any have blown—replacing them should fix the issue. The system is prone to interference from mobile phone signals, so avoid placing the key near metal objects before driving. If the problem persists, contact a repair shop immediately to avoid further complications. For prevention, regularly check the key fob battery and the car battery's health—replacing them annually is safer.
