Where can I get a car key?

You can go to the 4s shop to match it.

You can also go to some shops with keys outside. The remote control key is to match the chip in the key. Only with this chip can the remote control key remotely lock or unlock the car.

The chip in the remote control key is also responsible for controlling the start of the engine. Even if there is no key to start, you need the chip in the remote control key. If the chip is missing from the remote control key, only the mechanical key engine will not start. There is a battery in the remote control key, which can generally last for 2 to 3 years. If the battery is dead, it needs to be replaced with a new one. When using it at ordinary times, try to avoid remote control, which will increase power consumption.
