Remote keyless system works on the same principle as some television remote controls — sending pulses of radio frequency energy on a particular frequency. Remote keyless system actually consists of two separate units. One is a receiver control unit placed in the vehicle and wired to the systems that it will interact with and control. The other is a wireless transmitter known as a remote keyless fob that sends signals to the control unit.

Remote keyless systems operate by broadcasting radio waves on a particular RF frequency. Most remote keyless systems work on either 315 MHz or 433.92 MHz. Modern systems implement encryption to prevent car thieves from intercepting and spoofing the signal. The operating range of keyless remote system varies widely between manufacturers, usually in the range of 5m to 500m.
