  • K3 Tester Testing Device

  • 1.Frequency detection(Support frequency 100-999mhz)

  • 2.Infrared signal detection

  • 3.Ignition coil on-off detection

  • 4.Doorknob signal detection

  • 5.Frequency differentiation ASK/FSK detection


Q: How to use?


A: Simply place the remote control on the ‘RF’ square and press a button on your remote key fob, a signal will be sent to the K3 Tester and a numeric frequency will be displayed on the LCD screen.


Q:Why the frequency of the remote key is always different?

A:
Rolling Code Technology: Most modern car remote keys use Rolling Code technology. This means that every time the button on the remote key is pressed, the signal sent will change. This technology is designed to increase security and prevent signal interception and replay attacks. Every time the button is pressed, the remote control generates a new encrypted code, which has a mathematical relationship with the previous code but is unpredictable for eavesdroppers.


Frequency modulation: Although the operating frequency of the remote key (such as 315 MHz or 433 MHz) is fixed, frequency modulation technology is used when transmitting data. This means that the actual transmitted signal will undergo slight changes around the fundamental frequency to encode different information. This modulation makes the signal sent appear different each time
