Assuming that it does, the only option you have is to try all 999 codes
that remote will take as it appears the remote does not have a "search"
feature.

I'll give ya a +1 for both of these, in 1990 remote control sets were not
entirely standard issue, especially on the lower end (which MW falls into)
and trying all 999 codes might be the only way.

No one has yet mentioned the ultrasonic or RF remote controls....
