Thread: key fob

hi
trying to program my key
i know which is the lock button, it says on it
i have no idea what the other 2 symbols are

when i press the lock button, the red-light flashes
when i press the button that looks like a house, the light doesn't flash, should it ???
when i press the other button, whatever it is, it flashes red, is this correct

thanks, worked a treat, i couldn't believe it, first try
