How to program a new style fob on an old neco syst 

Ive got an Old style NECO fob which works the roller door and im trying to match it with the new style Neco fob, no blue light on either but it not working

How do you sync the new ones? I can't seem to get those to sync.

Could you tell me what the button mean on this new handset, you have two at the top which are lock and unlock I guess. Then what looks like a speaker with a cross though it and finally a bell on its side??

Nice video thanks. Wondering where the new remote control handset can be purchased? Any ideas please?

What happens when one of the buttons no longer works? How will they clone? My open button on my Neco has stopped working
