Do I need to replace the car key if I lost one of the two keys?

There is no mandatory requirement for car owners to replace all the locks, but replacing all the locks can prevent vehicle theft. Here are some additional details: 1. If you lose your car key and don't have a spare, you need to go to a service station to match a new key. You will need to provide the vehicle registration certificate, the owner's ID card, the 17-digit key anti-theft code, and the metal key tooth shape number. 2. Losing a car key can be troublesome, so daily precautions are necessary: (1) Keep the spare key separate from the main key, and don't lock the spare key inside the car. This prevents thieves from driving away with the car using the spare key if the main key is lost. (2) If you lose your key and there are valuables in the car, you can consult your insurance company about the compensation process for vehicle theft and ensure timely evidence preservation. (3) If your car doesn't have an anti-theft system, you can install one on the steering wheel to prevent theft in case the car key is lost.
