Is There a Difference Between the Two Car Keys?

[MacDawson]

Newly manufactured cars generally come with two keys, which are identical in style and function for the convenience of the owner. Car keys can be divided into three types: 1. Mechanical Key: Losing a mechanical key is both the most convenient and the most troublesome. The convenience lies in the fact that the main key and the spare key are exactly the same. If the main key is lost, you can simply purchase a key blank and have a new key cut to match the spare key. The trouble is that if someone finds the lost key, they can easily open the door and start the vehicle. 2. Ordinary Remote Key: An ordinary remote key consists of a remote control + a mechanical key. If one remote is lost, you only need to take the spare remote and a newly purchased remote to the 4S store to have them rematched with the car. The lost remote will then become invalid. 3. Chip Key: If a chip key is lost, you can buy a new key and take both the spare key and the new key to the 4S store for rematching. In this case, the person who finds the key can at most use the mechanical key to open the door but cannot start the engine. Of course, the most permanent solution is to replace the mechanical lock.
