What procedures are required to go to a 4S store if the car key is lost?

[LaLiam]

If you lose your car key and need to go to a 4S store, you should bring your driver's license, vehicle registration certificate, and relevant purchase documents. The 4S store will use the provided information to obtain the vehicle's anti-theft password and configure a new key. Precautions for keeping car keys: 1. Do not leave the spare key in the car: Modern car anti-theft systems are generally designed to protect the engine. Even if a thief makes a duplicate key to open the door, they cannot start the engine and drive the car away. However, the spare key can start the engine, so it must never be left in the car and should not be used as a regular key for long-term use. 2. Handle with care, protect from magnets and water: Dropping the car key or getting it wet can easily damage the internal chip components, causing the key to malfunction. In daily use, avoid subjecting the car key to severe impacts, exposure to liquids, and strong magnetic fields. Even if the key is not lost, if it is damaged, you will still need to spend money to replace it.
