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 synchronized 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 sync with the control unit and fail to operate the
system. To resynchronize the remote control simply press
sev-
eral times within range of the vehicle. The alarm will automatical-
ly resynchronize and respond to the transmitters normally.
