Dodge Dakota 2002 can anybody help?

So my boyfriend pulled my keys out of the
ignition but the truck was not off all the way
it was still on the on position but truck was
off so i had put my knife in the ignition jus
barely and it turned over it turned on and i
took off well multiple times i turned it off
and restarted it with my knife then tht same
day well my power steering fluid kind
leaked out i guess and steering wheel was
hard to turn wen i had parked it i think i
turned to far back well i finally got my keys
now and it still won't turn in the ignition i
was told to put a screw in underneath the
ignition Tumblr and it should pop off bt still
didn't work tried to pull it with another truck
it will go in gear bt when i start turning it
locks up again what can I do
