Is it necessary to go to a 4S store to replace a lost car key?

It is necessary to go to a 4S store to replace a lost car key. If you get a key duplicated outside, the lost key can still open the car, so you need to go to a 4S store to deactivate the original key. The 4S store will obtain the vehicle's anti-theft password based on the provided information and configure a new key. Do not leave the spare key in the car: Current car anti-theft systems generally target the engine. Even if a thief duplicates a key to open the car door, they cannot start the engine and drive the car away. However, the spare key can ignite the engine, so the spare key must never be left in the car, nor should it be used as a regular key for long-term use. 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.
