What are the reasons for the non-response of the one-key start in BAIC Huansu S3L?

Reasons for the non-response of the one-key start in BAIC Huansu S3L: 1. Smart key slot: Models with one-key start usually have a smart key slot. Some models place it inside the armrest box, while others position it under the mat of the cup holder. When the smart key runs out of battery, inserting the smart key into this slot will allow the vehicle to detect the key's presence after a short wait, enabling the vehicle to start. 2. Mechanical keyhole: Some models equipped with one-key start also have a metal keyhole for manual ignition. Locate this keyhole and insert the key blade from the remote key to start the vehicle like a conventional car. Typically, the mechanical keyhole is located behind the one-key start button, requiring the plastic button to be pried out to reveal it. 3. Place the smart key on the sensing area: When the smart key is out of battery, place the remote key on the one-key start button or other sensing areas and wait briefly. The vehicle will then detect the key, allowing you to start the vehicle. This method maximizes the smart key's sensing capability. 4. Replace the battery: Visit a 4S store to replace the smart battery with a new one, or purchase a battery of the same model online and replace it yourself. However, this method is time-consuming and not suitable for emergencies.
My BAIC Huansu S3L has failed to respond to the push-button start a few times. First, I checked if it was a remote key issue—depleted key battery is the most common cause. I examined whether the signal distance was too far or interfered with, and tried replacing it with a new CR2032 battery. A depleted car battery can also cause startup failure; using a multimeter to test the battery voltage—if it's below 12V, it might not hold a charge and would require a jump start. Next, I checked if the gear was in P or N position and whether the brake pedal was pressed firmly—if not, it won't start. Issues with the push-button start system, such as poor button contact or relay failure, or the anti-theft system being locked, may require trying a spare key. I believe regular maintenance is crucial—periodically checking the battery level to avoid breakdowns, handling simple issues myself, and promptly seeking professional repair if attempts fail. Never force-start the car to avoid damage.
