What are the reasons why the Baojun one-button start fails to ignite?

Here are the specific reasons why the Baojun one-button start car fails to ignite: 1. Steering wheel locked: The steering wheel lock is an anti-theft feature. After the car is turned off, if the steering wheel is rotated from the centered position to a certain angle in one direction, the steering wheel will lock. In the locked state, the one-button start function will not work. You need to turn the steering wheel left and right while pressing the engine one-button start button to release the tension and unlock the steering wheel. 2. Smart key battery dead: When the vehicle's smart key battery is dead, the key's transmission power is low, making it difficult for the sensors inside the car to detect it. In this case, the one-button start cannot complete the ignition.
I encountered this issue last time and it was quite urgent. If the one-button start doesn't respond, first check if the key battery has enough power. Sometimes it can't be detected if left in the pocket for too long—try pressing the key against the start button. If the gear is stuck in D and doesn't return to P, it can also lock the start function, so checking the gear position is crucial. The most common issue is an aging battery, especially in cars that are two or three years old—upon starting, you might only hear a clicking sound or notice the dashboard dimming. Occasionally, it's due to poor contact in the brake sensor, where a light press isn't detected. Additionally, short circuits from damp wiring during rainy days can also cause erratic behavior. Remember to keep an emergency power source in the car. If all else fails, open the hood and check if the corresponding fuse for the start function in the fuse box has blown. Avoid repeatedly forcing the start to prevent battery damage—calling for roadside assistance is the most hassle-free solution.
After several years of using Baojun, my summarized experience is: For starting failures, first check the key system. Weak key battery affects signal transmission—try using the physical key to open the door and then start the car. Next is the battery issue, especially during winter and summer when voltage fluctuates. Borrow a voltmeter; if it reads below 12V, it’s time for a replacement. Parking with wheels against the curb can lock the steering column and jam the starting procedure—just gently turn the steering wheel left or right to release it. Veteran owners remind us to pay attention to the fuel pump sound—if you don’t hear a humming noise during ignition, it might indicate a fuel system fault. Actually, developing the habit of straightening the steering wheel before shifting to P can prevent many issues. 4S shops offer free fault code detection, which is more accurate than small repair shops.
Last time at the 4S shop, the technician handled this kind of failure quite simply: mainly five possibilities. First, the battery terminals were oxidized with poor contact, so the copper pieces were removed and polished. Second, the receiving module behind the start button got dusty, so the contacts were wiped with alcohol swabs. Third, the rubber pad of the brake switch aged, causing the brake signal not to be transmitted, and it was solved by spending thirty bucks to replace the part. Fourth, the spring of the gear locking mechanism failed, and the transmission didn't truly return to position when in P gear. Finally, the electronic control unit froze, so the system was reset by disconnecting the power for five minutes. If you smell gasoline, it might be a faulty pressure relief valve. Have the technician check these items during routine maintenance, and you can basically prevent problems before they occur.
