Why can't the Hongqi HS5 one-button start work?
2 Answers
Hongqi HS5 one-button start may not work due to a dead key fob battery, it is recommended to replace the battery. The following are the specific details of the Hongqi HS5: 1. Vehicle positioning: The Hongqi HS5 is a sedan. The wheelbase of the Hongqi HS5 is 2875 mm, and its length, width, and height are 4945 mm, 1845 mm, and 1470 mm respectively. 2. Power: This car is equipped with a 1.8-liter turbocharged engine across all models, with the engine code CA4GC18TD-11. The 1.8-liter turbocharged engine has a maximum power of 180 horsepower and a maximum torque of 250 Nm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and a cast iron cylinder block. The engine is paired with a 6-speed automatic transmission from Aisin.
Having repaired cars for over a decade, I've encountered numerous cases of Hongqi HS5's one-button start failure. Depleted key fob battery is the most common issue—replacing the coin cell usually solves it. Signal interference is another headache, as nearby phones or metal objects can block the induction—it's best to keep the key fob isolated. The car absolutely won't start if not in Park (P), a must-check for automatic transmissions. Low battery voltage is particularly dangerous during cold winter starts when aging batteries struggle; dim dashboard lights are a telltale sign. Dirty or faulty button contacts may work after cleaning and multiple presses. Sometimes the anti-theft system falsely engages, requiring key removal and re-entry. Severe cases could indicate failed fuel pumps or ignition coils, requiring diagnostic trouble codes. Never force-start when one-button fails—methodically check simple causes before seeking professional help.
