Airkey recievers employ sophisticated code hopping technology and an encryption algorithm to achieve an extremely high level of security. Code hopping is a method by which the code transmitted from the transmitter to the receiver is different every time a button is pushed. This method, coupled with a transmission length of 69 bits, virtually eliminates the use of code ‘grabbing’ or code ‘scanning’.
