Shrink item effect versus locked door, what happens?


Unlike a growth effect, there is no clause about stopping the size change if one cannot burst something which restrains the change, so there are differing opinions about if the hinges and lock or locks (or some psionic or magical effect) on a door would restrain the shrinking effect it not.

Thus, can a door which is locked or otherwise restrained in some fashion be shrunk to gain access?
