[LailaLee]

If you lost the key, you need to replace the lock. You can go to a 4S store to replace the lock or get a new key. The data of the lost key will be deleted, and the vehicle cannot be started after deletion. Mechanical Key: Pure mechanical car keys are rare nowadays and are mostly found in some low-end models. These keys are as simple as different door lock keys, and one key can open the car door, trunk, and start the engine. So whether you have a spare key or not, it's best to replace all the locks of the car, otherwise the security risk will be very high. Electronic Key: Electronic anti-theft keys are mechanical keys with a remote control added. The function of the remote control is to open the car door or window. After losing this kind of key, you can use the spare key to copy and match a new one. However, although the lost key cannot open the car door with the remote control, it can still forcibly open the car door, trunk, or start the engine. Therefore, it's best to replace all the locks of the car.
