What to Do If One Key of a Keyless Start Car Is Lost?

[SanJesse]

If a key for a keyless start vehicle is lost, you can go to a 4S shop to rematch another key. Then delete the data of the lost key, so that the lost key cannot start the vehicle. First, confirm whether the key was lost unintentionally or due to theft. Extended information: 1. Unintentional loss: Look for a nearby car key specialist to erase the lost key information from the vehicle's system. This will disable the remote and start functions. If only one key is left, it is recommended to make an additional spare key, as the cost of rematching keys after losing all of them is extremely high. 2. Theft loss: It is recommended to replace all mechanical locks of the vehicle and then erase the data of the lost key. Even if the key data is erased, someone with malicious intent can still use the key to open the door and steal items from the car.
