if you took the keycode before the quest, you're stuck !
Weird thing is... for me I didn't get the keycode before the quest. And I progressed fairly far in her quest after that point... to the point where we already tried out her 2nd device and she needed to work on it some (the belt with the faptic egine).
Then next time I went into the lab I got the introduction again where I tell her my dad died then proceed to blow up a test tube of stuff. Then back up to the point where she tells me to get the keycode to get into her office. But at this point I already have the code... already have access to her office, and had already collected the safety glasses, lab coat, and blueprint for the xray glasses... so now all she has to say to me is "any luck getting that keycode?"
I wonder if getting the blueprint, lab coat, and safety glasses back in my inventory would allow me to move through again (then again even if it did, would it just loop again after the test of device #2?)
Anyone know if there's a console command to put items into your inventory?
