What are the reasons for the failure to start with one-key start in winter?

Reasons for the failure to start with one-key start in winter: 1. Spark plug damage; 2. Distributor contact burnout causing weak ignition voltage; 3. Dry ignition device damage, resulting in weak ignition; 4. High-voltage wire leakage; 5. Dead battery, empty fuel tank, or incorrect gear position; 6. Steering wheel lock; 7. Smart key low battery. The one-key start device is part of a smart car, a button device that simplifies the starting process and can also turn off the engine. Features of one-key start: 1. When the owner approaches the vehicle within about 3 meters, the door locks automatically open, disabling the anti-theft system; 2. When the owner leaves the vehicle, the door locks automatically engage, activating the anti-theft system; 3. When the owner enters the vehicle, just press the start button to use the car without a key.
I ran into the same issue this morning and it took me quite a while to figure it out. Car batteries are most prone to problems in winter—cold weather causes sudden voltage drops, especially with older batteries that have been used for three years. Last time, I had to get a jump start. Another thing is engine oil, which thickens in low temperatures like honey coating the engine. For older cars, using thinner oil like 5W-40 works better. Another pitfall is the fuel pump—if there’s water in the tank that freezes, it can’t supply fuel. I usually add a bottle of fuel additive before winter to remove water. The most frustrating issue is the starter—frozen gears won’t engage, and that’s a job for the repair shop. A temporary fix is to turn off all electrical devices before trying to start the car, and avoid repeatedly turning the key to prevent battery damage.
