Remote syncing?

New remotes received today only blink red on all 3 buttons. My garage door opener light is solid green. What do I have to do to sync them?

Would you please send me your opener motor’s model number? so I can check.

When we check learn button color, it means the learn button itself (not the opener light color).


Lift-Master 1/3HP Professional Line

It seems the opener is a Security+ model.
In this case, please make sure our remote buttons are in Mode 1 (solid led).
And try program to opener motor, thanks.
