Sears Craftsman garage door opener… the smaller the better… i would prefer a key chain style one… but anything will do… i seem to lose them sometimes 
and spare keys… damn i suck…
anybody have an extra one laying around?
they have small universal joints at home depot pretty cheap. i had to get one a while back.
just curious whats pretty cheap… ill have to swing in or call em later…
