Where is the car keyhole located?

[Joshua]

The car keyhole is located on the driver's side door handle. The functions of the car key include: 1. After the vehicle is turned off, long-press the lock button on the remote key to close the windows; 2. The red horn-shaped button on the key serves both as a vehicle locator and an emergency function; 3. It has an automatic trunk-opening feature. The principle of the car key: The owner emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator motor or electromagnetic coil performs the locking or unlocking action. The method to replace the car key battery is: 1. Use a flat-head screwdriver to pry open the key casing; 2. Remove the battery from the circuit board; 3. Replace it with a new battery and close the casing.
