The garage door opener is located in the overhead console. The valet switch provides battery voltage to the garage door opener. If battery voltage is lost due to a condition such as a dead battery, the garage door opener unit relies on the non-servicable internal power backup supply. The unit is programmed using the customer's hand-held transmitters for the garage door(s), electric entrance gates, or lighting and security systems.

The garage door opener is rolling code capable. Rolling code is a system that allows the code that the customers receiver receives from the garage door opener to change every time the garage door opener is used within operating range of the receiver. When the receiver and the garage door opener are initially programmed together, a code is established, a new code is created for every new transmission. The software in the receiver recognizes the garage door opener and accepts the new code.

The garage door opener is compatible with most, but not all types and brands of transmitters. If a problem should occur with a compatibility conflict with a transmitter, call HomeLink™ at 1-800-355-3515.

The garage door opener is a transmitter operating between 288 and 399 MHz. The power and range of the transmitter is limited to comply with laws governing the generation of radio frequency interference (RFI). The transmitter is programmed by the user to accept the signal generated by the user's transmitter(s), refer to Garage Door Opener Programming - Universal .

The garage door opener has 3 buttons that may be programmed for individual transmitter/receiver combinations to control up to three garage door openers, security gates, and lighting systems. Each button represents a transmitter code section of the transmitter, which operates separately from any other button and may be considered a separate transmitter. Operation consists of simply pressing a button to activate the corresponding transmitter.
