Article does copy signal, but does not send it correctly. Useless article. Bad service, don't respond when you ask a question to this store. I only receive a standard message about the delay of the article but no substantive answer about my question. Very disappointing service.
excellent product. finally one that just works. for anyone curious this is compatible with rolling code remotes. 1. Press a+b together. 3 flashes. Release B. But keep holding A. press B 3 times. you'll see a flash. codes cleared. 2. now when you press a or b it should not give you any led light. this is good! 3. get your new remote. press the button you wish to program and hold. while holding. press the button on your old remote. the new remote should flash. release both. now press the button on the new remote it should flash and also trigger your gate or motor.
