The circuit principle of the car electronic code lock is as shown in the figure. ICl is a dedicated password lock integrated circuit 5G058. Its pins 1 to 6 are connected to an external key switch to the positive pole of the power supply. These are 6 valid input keys. Unlocking must follow the sequence Sl ~ S6; the key switch S7 connected to pin 8 is a false key switch . Key input terminal, you can randomly connect one or several keys and insert them into the keyboard to make them look fake; pin 9 is the key indicator terminal. When each key is connected, the external light-emitting diode LEDl will light up to confirm that the key input is valid; pin 10 is the alarm At the output end, if the input is not in the sequence of Sl ~ S6 or exceeds the effective unlocking time, it will output high level and trigger the IC2 anti-theft alarm language. The effective unlocking time is determined by the size of the capacitor C1 and the potentiometer RPl.
