Help! I'm trapped in the Nashville Facility Entrance

[Byrdsong]

I went in through the service shaft in the sewers, and then came crashing down with the elevator, so that one is destroyed. The other elevator is under lockdown, and I assume I have to activate it with the elevator terminal in the room with the surveillance monitors and the servoshell. But I can't hack into it because I used up my last hacking tool on one of the door terminals. I've looked everywhere and can't find a way out. The telephones and intercoms are all dead. It seems I'm locked in now..
Is there *any* other way to get out of the entrance level?!

Shouldn't there be an elevator control panel? I seem to recall there being a keycard as well so maybe that opened it? Been a while since I did the entrance part, but I don't remember needing hacking to progress.

Oh man, thanks so much! I forgot to take the keycard from the dead head security guy outside the room. I'm an idiot..
