"Yeah, I don't buy this line of argumentation. Suppose the locked room is an apartment and the person with a key is your landlord"

So he would not be Breaking and Entering, and if he has a valid reason such as emergency it would be legal.

There are different crimes with different punishments and it's important the right ones are applied.

Fraud and theft are different. Manslaughter and murder are different. Sexual harrasment and rape are different.
