Cobra alarm, model 7777 red light stays on remote fob?

I've just found the same problem with mine. The light comes on, stays on or flashes. With some touching, it stops, but starts again by just moving the fob. this even sets the alarm as I drive along.
I got a new battery but to no avail.
It looks like the button n the circuit board is stuck down. It does not depress in the same way as the other button.
Looks like I need a new circuit board or complete fob. Now where could I get one of those?
