Whenever I have to open something that requires using the ingame keypad to enter a numeric code, I find that inputting a random number can open everything everytime. Even if I close them and try to open them again.
That gives me unlimited access to Dr. Fred's lab after I get the key to open the "Sekrit Lab" door.
I believe that it has something to do with the method used to bypass the copy protection nuclear door.
By the way, I am playing Maniac Mansion v2 with ScummVm 0.12.0 on Windows Vista.
