unopenable
Cannot be accessed
Unopenable describes something that cannot be opened, whether by design, damage, or sheer difficulty.
A rusted lock may be unopenable without the right tools.
Packaging earns the label when it defeats all reasonable attempts: The unopenable blister pack finally yielded to scissors.
