Can't leave the Tattoo shop

[Plex]

I did the hijacking thing with the dead woman and I think I'm done with this place,
but I'm unable to leave it now because the door won't open. grabbing it and trying it to open like other doors won't do a thing..
Daniel also said "what the ****" when I moved towards the door... or am I'm just missing something?

I haven't played in a while, but you could be missing something, that's usually why you can't progress an area. From memory there is lots to interact with, both out the back and in the front of the store.

I believe there's a keypad on the back of the chair. You insert the code there that you retrieved from the hijacking and the door opens.
