I just tried this and it worked. You could do the following:
mv unlock.x unlock.shc (use any name you want, but I'd use something more meaningful than a .x extension) chmod 500 unlock.shc
Now you should be able to call unlock.shc exactly the way you previously called your unlock script, with the same results.
