Decryption of access codes of diverse protocols in barrier operator systems

A method for operating a barrier operator system that actuates a movable barrier, the method comprising:

• entering a learn mode in response to user input;
• while in the learn mode,
• receiving a learned command encrypted in accordance with one of a plurality of encryption protocols,
• indicate which of the plurality of encryption protocols the learned command was encrypted with, and
• in response to receipt of the learned command, open a window of time for receiving an unlearned command encrypted with another of the plurality of encryption protocols,
• receive the unlearned command within the window of time and indicate which of the plurality of encryption protocols the unlearned command was encrypted with,
• learn the unlearned command encrypted in accordance with a second encryption protocol;
• wherein the learned newly received command and the learned command instruct the barrier operator to actuate the movable barrier;
• exiting the learn mode;
• actuating the movable barrier in response to receipt of the learned newly received command, or in response to receipt of the learned command.

A method for programming a barrier operator system that actuates a movable barrier, the method comprising:

• causing the barrier operator system to enter into a learn mode;
• transmitting a learned command encrypted in accordance with a first encryption protocol to the barrier operator system;
• indicating that the learned command was encrypted in accordance with the first encryption protocol;
• in response to receipt of the learned command, opening a window of time for receiving an unlearned command encrypted in accordance with a second encryption protocol;
• transmitting a new unlearned command encrypted in accordance with the second encryption protocol to the barrier operator system;
• and
• receiving the unlearned command within the window of time and indicating that the unlearned command was encrypted in accordance with the second encryption protocol;
• wherein the new unlearned command and the learned command instruct the barrier operator system to actuate the movable barrier.
