Keyless remotes contain a short-range radio transmitter, and must be within a certain range, usually 5-20 meters (15-60 ft), of the car to work. When a button is pushed, it sends a coded signal by radio waves to a receiver unit in the car, which locks or unlocks the door. Most RKEs operate at a frequency of 315 MHz for North America-made cars and at 433.92 MHz for European, Japanese and Asian cars. Modern systems implement encryption to prevent car thieves from intercepting and spoofing the signal.
