Abstract:
1. A method for training a vehicle-based trainable transmitter to send an authenticated transmission to a receiver for a garage door opener using a data code from an original hand-held transmitter, the method comprising: transmitting, from the original hand-held transmitter and in response to a single user input, the data code at a first frequency and separately at a second frequency, wherein the first frequency is configured for reception by the receiver for the garage door opener and the second frequency is configured for reception by the vehicle-based trainable transmitter; receiving, at the receiver for the garage door opener, the data code at the first frequency and causing the garage door opener to actuate in response to the reception; receiving, at the vehicle-based trainable transmitter, the data code from the hand-held transmitter at the second frequency, but not at the first frequency; identifying, by the vehicle-based trainable transmitter, the data code at the second frequency; storing, by the vehicle-based trainable transmitter, the identified data code; associating, by the vehicle-based trainable transmitter, the stored data code with a particular user input device of the trainable transmitter; transmitting the data code to the garage door opener and causing the garage door opener to actuate in response to the reception; and wherein the receiver is configured to recognize the data code transmitted at both the first frequency and the second frequency.
