Every car will have an anti-theft password configured with the car. As long as the owner provides the driving license and identity information to the 4s shop, the 4s shop can obtain the anti-theft password of the car according to the provided information and configure a new key. At the same time, the lost key data can be erased, which means that the lost key becomes an illegal key, the vehicle will not be able to start, but the door can still be opened, so the 4s shop will also recommend replacing the whole car lock to ensure safety.
Matters needing attention in using car keys:
1. Don't touch metal objects: Many car owners like to drop heavy decorations on their car keys, and some male car owners even string many other keys together. When the car bumps and jumps, too many falling objects on the key will wear the contact point between the limit element and the switch through the lock core, which will lead to its premature relaxation and damage. Over time, the engine will not start or shut down effectively due to power failure during driving.
2. If it is put together with other keys, the key is made of metal. When intelligent key touches or is covered by metal objects, intelligent key may not be able to work.
3. The spare key should be separated from the master key. Don't lock the spare key in the car, especially when starting with the key or using the engine to prevent theft. The spare key can completely start the engine.
