Just read the instructions: - Clear the memory by pressing the 2 keys (caution, about a dozen seconds) - Take the remote control to duplicate, simultaneous pressing the button on the remote control to duplicate and on the A or B button on the Jolly Open (very fast this time) and voila.
For my part, I duplicated my door control on the 2 buttons on the Jolly Open, as it will serve me on a motorcycle (thus with large gloves not practice).
