Remote control keys allow car owners to easily unlock and lock their cars from a certain distance, greatly improving the convenience and safety of using the car.

[0003] Car keys consist of a shell, circuit board, battery and buttons. Most car keys currently on the market have buttons that are generally set on the shell and run through the inside and outside of the shell. Pressing the button triggers the circuit board inside the key to realize the remote control function. There needs to be space between the button and the shell for the button to move up and down. The waterproof performance is poor. When using the key on rainy days, rainwater can easily flow into the key through the gaps on the edge of the button, causing damage to the circuit board and battery, and greatly shortening the service life of the car key.
