What to Do If You Lose Your Smart Key with One-Button Start?

Take the spare key to a 4S dealership to have a new one reprogrammed. Once the new key is successfully programmed, the unlock system's code will automatically be updated, rendering the original key invalid. After getting a new car key, although the original key will no longer work, the mechanical key can still unlock the doors. Therefore, it's necessary to replace all the mechanical locks on the entire vehicle.
Last time I lost my car key, it really freaked me out! That day after parking at the shopping mall, I realized the key was gone and searched all my pockets in vain. My first reaction was to remotely lock the doors using the app, but couldn't start the car. I immediately contacted the 4S店, and they asked me to bring the vehicle license and spare key to the store for a replacement. They said the car needed reprogramming to recognize the new key, which cost over 800 yuan, and I had to wait two days for an appointment. The whole process reminded me that smart keys are linked to encrypted systems, and losing them makes the car vulnerable to hacking and theft, posing high security risks. Now I've bought a key case and attached a Bluetooth tracker to prevent similar incidents. Don't underestimate such a small thing—if it happens, deal with it immediately, or it could lead to greater losses.
