  • Automobile key programmer and automobile diagnostic instrument
    Patent number: 11935344
    Abstract: This disclosure relates to the technical field of automobiles and discloses an automobile key programmer applied to an automobile diagnostic instrument, wherein the automobile key programmer includes an activation coil, a first changeover switch, a second changeover switch, an infrared modulation circuit, an amplitude shift keying modulation circuit, and a frequency shift keying modulation circuit; when the first changeover switch is not powered on, the infrared modulation circuit provides a resonant voltage for the activation coil; when the first changeover switch is powered on and the second changeover switch is not powered on, the amplitude shift keying modulation circuit provides a resonant voltage for the activation coil; when both the first changeover switch and the second changeover switch are powered on, the frequency shift keying modulation circuit provides a resonant voltage for the activation coil; only one coil is required in the automobile key programmer to change voltages.
