In 2k (also in older versions but slightly diff path);
In the VBE;
"Tools-VBAProject-Properties" -Protection tab.

One small word of warning (from sad experience);
If you protect it in one version then try to open it in a prior version
it won't allow you to enter the password.
Also, it is not foolproof.
