mechanism
The word can be used for physical objects, like the gears in a clock, or for abstract ideas, like how a law works. When talking about psychology (like "defense mechanism"), it refers to an automatic way the mind protects itself. It is a countable noun, meaning you can have one mechanism or many mechanisms.

Just a heads up, the locking mechanism on the unit is acting up.

Stop beating around the bush. Is it actually broken?

David uses 'acting up' (phrasal verb meaning malfunctioning) to downplay a problem, while Victoria uses the idiom 'beating around the bush' to demand a direct answer, highlighting their power dynamic.
