Doors and locks should be treated identically in-game (more below)

[libraun]

For example, "insert key in door" should be interchangeable with "unlock door with key".

Here are a couple examples:

insert key in door
The Brass Knobbed Door can't contain things.

insert key in knob
Sorry, I don't understand what "knob" means.

insert key in key hole
You can't see any such thing.

insert loose brass key in small key hole
Sorry, I don't understand what "small" means.

insert loose brass key in key hole
I only understood you as far as "insert loose brass key in key" but then you lost me.

insert key in hole
Sorry, I don't understand what "hole" means.

The Brass Door seems to already have this desired behavior
