QUESTION: Where is the key to the mansion garage in Mission 2?

[Gungrave]

I've literally arrested EVERY guard in this obscenely large level, checked every building, collected everything I can shortof the final objective. Even with all of that I still don't know where the ♥♥♥♥♥♥♥♥♥♥ key is for this door.

Screenshot below shows you the garage with one of my cops at the highlighted door.

I think its a extra job. Because i started it with the extra job and got the key on 1 character in the beginning already.

The key was given to you from the start, to the cop you assigned for the job or a random one if you haven't tasked anyone specific. Check each of your officers' inventory (click one and press space), one of them should have it.

None of them had it, I tried every single one of them on that door. Eventually I gave up and just finished the mission.
