What to Do If You Lose One of the Two Car Keys?
2 Answers
There are two ways to handle the situation when you lose one of the two car keys, as detailed below: 1. Change the password and reconfigure the key to render the original key invalid. Depending on the car model, the service station will require the owner to provide the 17-digit anti-theft password for key configuration. After obtaining this password, the service station will, on one hand, configure a new metal key for the owner and, on the other hand, modify the vehicle's computer parameters to set the lost key as an illegal key (although this key can still unlock the car door, it cannot start the vehicle). 2. Replace all the car locks. This method is more secure but more costly. For an average car priced around 100,000 yuan, replacing all the locks may cost between 3,000 to 5,000 yuan, with prices varying significantly depending on the car model.
Last time I lost one of my car keys, I immediately drove to the 4S dealership with the remaining usable key to address the issue. They recommended promptly getting a new key replacement while simultaneously deactivating the lost one to prevent unauthorized individuals from potentially stealing my car. Most modern vehicles now come equipped with smart anti-theft systems, requiring a chip signal reprogramming during key duplication. The cost isn't cheap - basic keys might cost tens of RMB, but smart keys with remote functions can range from hundreds to over a thousand, depending on the car model. I always use a keychain to keep my keys secure in my pocket to avoid losing them again. If you lose a key, it's best to resolve it the same day rather than delay and increase risks - vehicle security is far more important than saving money. It's also wise to keep a spare key safely stored at home as backup for emergencies like this.
