433MHz Universal Cloning Door Remote Control Key can't clear 

Press A and B together for 2s and then holding A until the end of the process release B for 0.5s then press B for 0.5 seconds. Release B for 0.5s, press B for 0.5s, release B for 0.5s Now you will see the quick flashes and you can release A. Buttons should now all be cleared

Same thing overhere too, I have put the A&B together, no result....must be in the software....

please consider replacing the batterie(s) and try. I had this issue in the past and thought it was faulty because it was still working and showing light.

Same here. Why they send it programmed?

after flashing realise one of the button and press 3 time ,while the other finger continues hold on the first button

Hi, not sure if someone has the same issue. I have the same garage fob, but a few weeks after programming it's not working and I have to do the programming again. I even bought two and they both lost programming at the same time. Does anyone know what could be the reason?

for anyone who facing this problem, actually it become like that because the data have been cleared or no data found in the remote, no need to clear data anymore, just proceed to copying data. like this comment if your problem solved.

Same problem for me with 4 remote 2022 France

Try pressing c and d together until it flashes. Then release once it stops flashing. Now press a and b together until it flashes and stops again. Then press and keep pressing A while pressing the button of the remote you want to copy. Repeat for b, c and d

same problem here both just flash and nothing else

Same problem at February 2022 in Spain 😳

guys, i am facing the same problem, how do you guys settle this problem?

You have to press the buttons at exactly the same time. the click should be like one sound.. not two clicks.
