Can anyone tell me how(if possible) to program a garage door door opener with dip switches to a unit without them?

I think the answer is you can't. The dip switch type was the old designs
that used the switches to set a freq. With ten switches you'd get 1000
codes, not much security there, your neighbor could happen to pick the
same codes or a thief could try them until he finds the right one.
The newer ones using pseudo random keys and are far more secure.

Trader is right. There are a **** load of different garage door
remotes. I just spent about 40 minutes getting educated myself. I was
trying to match up 5 different Sears remotes and it turns out I have 4
different styles and they all look identical but they are not
interchangeable. These are also the kind without switches.

If it turns out you can use a Liftmaster/ Craftsman/Sears 139.53879 I
have one I will send you. It won't work with anything I have.
This is a fairly good resource. They do other brands
