A mask cannot be locked.
Understand the Problem
The question seems to be asserting that a mask cannot be locked, which could relate to a discussion about security features or functionalities related to masks, perhaps in digital platforms or physical masks used in security settings.
Answer

In After Effects, you cannot 'lock' a mask directly like you can with layers, but you can use a workaround by locking the layer the mask is on.
