What are the reasons why the Hongqi HS5 one-button start cannot start?
2 Answers
One-button start failure could be due to a malfunctioning one-button start button, which may have a short circuit or open circuit fault inside. It could also be an issue with the smart car key, such as the key being out of battery or experiencing interference, which would prevent the one-button start from working. Additionally, the problem might lie with the vehicle's engine. One-button start steering wheel lock function: The steering wheel lock is a simple anti-theft feature. When the car is turned off, turning the steering wheel from the centered position to one direction (usually to the left) by a certain angle will cause the steering wheel to make a "click" sound and lock. In the locked state, the steering wheel cannot be turned, the key cannot be turned, and the car cannot be started, thus achieving the anti-theft function. One-button start device: The one-button start device is part of a smart car, a button device that simplifies the starting process and can also turn off the engine. This device can be retrofitted at the original car key lock position or as an independent panel modification. Automatic steering wheel lock situations: When the engine one-button start button is in the OFF state, the steering wheel locks for anti-theft purposes. The steering wheel will also automatically lock when the car door is opened or the smart key is removed from the smart key cylinder.
I previously encountered a situation where the Hongqi HS5's one-button start wouldn't work, which was quite annoying but don't panic. The most common reason is the car battery being dead, possibly due to long-term parking or forgetting to turn off the lights. Check if the headlights still turn on; if they don't, it's likely a battery issue requiring a jump start or replacement. Another common issue is a blown fuse, especially the one for the starting system—open the fuse box to see if any are blackened and try replacing them. Weak key fob battery can also make the button unresponsive; simply replace the key battery. Also, if the brake pedal isn't firmly pressed, the start button won't respond, so make sure to press the pedal firmly. If all these are ruled out, it might be a faulty starter relay or control module, and it's best to visit a repair shop for diagnosis. Don't waste effort repeatedly pressing the button—for safety, seek professional help to avoid causing more damage.
