Hello everyone. I lost my garage door remote control when shopping in the parking lot. Could not find it again unfortunately. So a garage door remote control bought again (the before was already an from the internet, same model – had good experiences with it – see picture) Full of action then on the small standing ladder and first pressed the small black button 1 second. He started to flash for about 5 seconds and in this time I had the button on the remotebed Ienung held down. – Nothing happens. Try again. Again no gate opened or closed. The small black head held down 2-3 seconds, then the light flashed faster. Again the remote control held down until the red light glowed normally. Another attempt. Nothing. Third attempt with the remote control at another place from the door opener. Nothing happens. Next try the small black button held about 4 seconds. The red small lamp flashes ever again. Again, the remote control held the button pressed. Nothing. Try again elsewhere. Again, no reaction from the door opener. What am I doing wrong? What could this be? Have included 2 pictures. Door opener and remote control. As I said, I had the remote control before and it worked. Please for your help. Thank you.
