Code Hopping ™
The receiver and transmitters each use a mathematical formula
called an algorithm to change their code each time the transmit-
ter is used. This technology has been developed to increase the
security of the unit. The control unit knows what the next codes
should be. This helps to keep the transmitter “in synch” with the
control unit even if you use the remote control out of range of the
vehicle. However, if the transmitter has been pressed many times
out of range of the vehicle, or the battery has been removed, it
may get out of synch with the control unit and fail to operate the
system. To re-synch the remote control simply press the arm/dis-
arm button of the remote control several times within range of the
vehicle. The alarm will automatically re-synch and respond to the
transmitters normally.
