How to disable anti-theft on 94 Vision

Hey guys,

So my roommate took the train down to NYC today, and managed to lose
the keys to her 1994 Eagle Vision somewhere down there. When she got
back to the train station, she had the plain metal key that would open
the doors, etc.. But without the remote she can't get the factory
anti-theft system to disable.

We really doubt we'll be able to recover her keys, so how can we
disable this anti-theft system so she can actually use the car?

Thanks in advance for any advice you can offer.
