Can i make my old openers, ones with the little switches inside, to work with a later model door opener? my "new" door opener uses a simple switch to set coes whereas the old hand helds have that row of switches to move to reset. My "new" Craftsman opener is about 5 yrs old!! but i'm the 1st person to unpack & use it, only came with 1 handheld which works fine but i'd like to use with my 2 older hand helds Thanks -Roy -Ontario, Canada
