I cant be certain but you could try something like:
press programming button in control unit, this probably does a search for a given time maybe 10-30 secs? Then press a button on the keyfob say open/up if the door is closed or vice versa if done within the alloted time then the door should open/close you may/maynot have to press the programming button a second time to accept?
worth trying different combinations of button presses to see if you get lucky, one thing make sure you have fresh batteries in the fob.
If the unit has a rolling encryption system then you might have problems getting the fob and control unit synchronised again, it maybe that there is a way of resetting them both but without knowing the make and model it may prove hard?
ps just looked again at your first pic and there is a serial number on a label inside the unit, you could be lucky if you type it exactly as is into google, I've found several manuals for things that way in the past.
