What is the reason for the non-response of the Changan CS75 one-button start?

The reasons for the non-response of the Changan CS75 one-button start are: 1. Operational error, where the button is pressed without stepping on the brake, causing the car to power on but the engine not to start; 2. The gear is not in the P position; 3. Frequently placing the car key near electronic devices, causing interference with the low-intensity radio waves in the key; 4. The car key battery is dead; 5. The car has malfunctioned. Taking the 2021 Changan CS75 Glory Million Edition 280T Manual Elite as an example, its body dimensions are 4650mm in length, 1850mm in width, and 1715mm in height, with a wheelbase of 2700mm. It is equipped with a 1.5T turbocharged engine and matched with a 6-speed manual transmission.

Last time my CS75's start button didn't respond, which really confused me. I thought it was broken, but it turned out the key was still in my bag and hadn't been taken out. The one-button start system requires the key to be sensed inside the car—if it's too far away, there's no signal. It could also be that the key battery is depleted; those CR2032 small batteries need replacement after prolonged use. Additionally, when the vehicle's auxiliary battery is low on power, the start system may fail, especially in cold weather. I recommend first checking the key's position and battery status. If the problem persists, try restarting the vehicle—turn off all power, wait a few minutes, and then start it again. Sometimes it's just a random software bug, and a restart might fix it. But don't ignore safety; if it happens frequently, don't risk driving and head to a professional repair shop immediately. Changan service centers are quite reliable—they can test the entire circuit and modules. For regular maintenance, pay attention to battery replacement and checking the battery to prevent issues proactively.

As a seasoned driver with years of experience, when encountering a malfunctioning one-button start in the CS75, I would calmly troubleshoot. First, ensure the key is near the driver's seat, as the one-button start relies on wireless signals and won't work if the key is too far away. Second, check for insufficient battery power, which could be due to excessive use of electrical devices or prolonged parking leading to low voltage. In such cases, measuring the voltage or attempting to charge the battery might help. Additionally, the start button itself might have poor contact or internal module failure, requiring professional diagnosis. I've tried restarting the system—pressing the button without stepping on the brake for a few seconds before retrying. If that doesn't work, seeking help from a repair shop is the next step. Safety comes first; avoid forcing the start to prevent damage to the vehicle. The one-button start offers convenience but requires regular maintenance, such as replacing the key battery every two years.

As a CS75 owner, when the one-button start doesn't respond, start with simple checks. First, replace the key fob battery, as Chang'an's key fobs consume power faster. Then, check the vehicle battery using a voltmeter or jump-start tools to see if it's low on power. The start system relies on circuit control, so it may fail if there's a short circuit or sensor malfunction. Safety tip: If this happens while parked, don't panic—check and restart the vehicle. While one-button start is convenient for daily use, understanding common issues brings peace of mind. It's recommended to maintain the battery every six months to avoid sudden breakdowns.
