What is the reason for the Lavida's one-button start not responding?

Lavida's one-button start not responding reasons are as follows: 1. Smart key battery depletion: This situation is most likely due to the smart key's battery being depleted, causing the start system to fail to detect the weak radio waves emitted by the smart key. You can pick up the smart key and place it on the start button, then press the button to start. 2. Insufficient battery voltage, dead battery, or battery damage: Failure to start may be due to reasons such as leaving the headlights on for a long time, resulting in battery depletion or the battery's lifespan expiring. Generally, replace the battery promptly according to the maintenance manual. If the battery is dead, you can use another battery to start or use the push-start method.

I had a similar issue with my Lavida recently—the one-button start suddenly stopped responding, which was really frustrating. At first, I thought it might be the key, so I replaced the battery. The Lavida requires the key to be within the sensing area to start, so don’t place it too far away. Also, make sure the gear is in P (Park), or the button won’t respond. Pressing the brake pedal is crucial—it must be fully depressed for the system to receive the signal. I checked the button surface myself; dust buildup might affect contact, so try wiping it gently with a soft cloth. Another thing to consider is the fuse—sometimes a blown headlight fuse in the engine compartment’s fuse box can cause starting issues. In my case, it turned out to be an electronic problem linked to a recent windshield wiper malfunction. Eventually, I had it fixed at the 4S shop. Remember, don’t force it—regular maintenance of the car key and electronic components can prevent such embarrassing situations.

I've been driving this Lavida for several years and have seen many cases of the one-button start malfunctioning. My suggestion is to start with the key: if the battery life is up, it will fail—try replacing it with a CR2032 model. Keep the key away from interference sources like phones and place it in the center console sensing area. Press the brake pedal firmly; the Lavida's design is sensitive, and if you ease up slightly, it won't start. After confirming the P gear is correctly engaged, check if the start button has physical damage or water ingress—apply a bit of cleaner for lubrication. If all these are normal, inspect the car's fuses, particularly those related to the headlight circuit under the steering wheel cover panel. In my case, it was an unstable generator output voltage causing a sensing fault, which required professional diagnosis. In short, don't panic—it's usually not a big issue. Keep a mechanical key or a remote assistance app handy for emergencies.

The non-response of the Lavida's one-button start is commonly caused by low key battery, poor button contact, or incorrect gear position. Replace the battery when the key is near the button. Ensure the brake is fully depressed and the car is in P gear, as the Lavida requires strict positioning. Clean the button surface if it's dirty. Check the engine compartment fuse box and replace any blown fuses. Circuit short circuits are also common, especially in humid weather with aging wiring. Sensor malfunctions require professional diagnosis—avoid self-disassembly. If unresolved, try starting with the mechanical keyhole or jump-starting the car.
