That time I lost my car key and was running around in a panic. I quickly rummaged through my bag for the spare key, luckily my wife had it at home. If there was no spare key, I would have had to immediately call the 4S store—they require the vehicle registration certificate and a photo of my ID to verify ownership. The new key needs computer programming to match, and the whole process takes two to three hours. Some car models can use a mobile app for emergency starting, like my car, which has the brand's exclusive app installed. After real-name authentication, it can serve as a temporary key. Never try to pry open the door or dismantle the circuit board yourself—modern car anti-theft systems are extremely sensitive, and mistakes can lock up the entire electronic system. As a last resort, call a tow truck, and remember to have the repair shop make two new spare keys just in case.
First of all, don't randomly unplug any wires when this happens. Last time my friend lost his car keys in a shopping mall, I helped him contact automotive rescue. The technician came with a diagnostic computer, verified the vehicle license information, and began the operation. He first removed the decorative panel under the steering wheel, located the OBD port to connect the device, and then reprogrammed the key recognition system. The whole process cost over 300 yuan, which is half the price of a dealership. Nowadays, high-end models generally have an emergency induction area hidden in the center console—pressing the spare mechanical key against it can start the ignition, but you need to check the specific model's manual. Important reminder: Never use those OBD unlocking gadgets sold online, as they can easily fry the car's computer motherboard.
