Abstract
A method for training a trainable transmitter in a vehicle that includes receiving a request to enter a training mode of the trainable transmitter from a user, beginning a training mode of the trainable transmitter, receiving a control signal from an original transmitter associated with a remote control system, detecting a frequency and control data of the control signal. The method further includes determining if the control signal is a fixed code signal or a rolling code signal. If the control signal is a fixed code signal, storing the detected frequency and control data. If the control signal is a rolling code signal, comparing the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shifting the detected frequency to match one of the predetermined frequencies.
