You can get a replacement key at the 4S shop if you lost one car key but still have another one, and they can also erase the data of the lost key. Contact a professional locksmith: If the vehicle is far from the spare key or the spare key is also lost, you will have to call a professional locksmith to unlock the car. Usually, relevant documents such as ID card and vehicle license are required. Get a new key from the 4S shop: Every car comes with an anti-theft code. The owner only needs to provide the vehicle license and personal information to the 4S shop, and the 4S shop can obtain the anti-theft code of the vehicle based on the provided information and then configure a new key.

As a veteran driver who often loses car keys, I once lost one at a supermarket. When only the spare key was left, I immediately went to the 4S shop. They easily made a new key by programming it with the remaining one to match my car's locking system. The whole process took less than half an hour and cost about 300-500 yuan depending on the car model. I suggest you get it done early to avoid more trouble if the other key is lost. The 4S shop is reliable and secure, and the anti-theft system can be updated. An additional reminder: bring your vehicle registration and ID card to prove your identity to avoid a wasted trip. Don't save money by going to a roadside stall, as it might be unsafe. Remember to regularly check the condition of your spare key and develop good habits to minimize losses.

I'm the budget-conscious type, so getting a car key replacement requires careful calculation. A dealership can definitely make you a new key. If you only have one remaining key, it can be used as a reference to program the new one. Costs vary by vehicle - basic remote keys run around 200-400 RMB, while smart keys may cost 800 RMB or more, with luxury vehicles being even pricier. Programming takes time, starting from 30 minutes; some vehicles require reprogramming the entire key system for an additional fee. Always get a quote first before committing. While dealerships offer guaranteed quality, authorized service centers or online services might be cheaper options when on a tight budget, though with slightly higher security risks. Address this early to avoid doubled costs if you lose your second key, which also increases theft risk. Keeping spare keys handy saves both money and peace of mind.

From a safety-first perspective, if you've lost a car key, hurry to the 4S store to get a new one. The remaining key can be used in the programming process, which takes about 20 minutes. Anti-theft is crucial; a lost key might be picked up and used to drive away your car. The 4S store will promptly update the system to plug any vulnerabilities. The cost is generally around two to three hundred yuan, a worthwhile investment for security. Bring your ID to prove ownership and save time. Don't delay to avoid increasing the risk if the other key is also lost. Professional and reliable service prevents potential hazards.
