How do i replace lock cylinder in a 1993 pontiac grand prix automatic?

SOURCE: Pontiac Grand Prix 98

When the window is not used often or gets a little older the motor can "Hang Up" You might try having someone hold the down switch on the drivers door while you slam the door. This will sometimes jar the motor enough to make the brushes contact and start working.

Does it turn? Or is it **** in the lock position.

I have 07 Pontiac Grand Prix, the wrong key was inserted into the ignition the other day. Now when I try to use the correct key it will not insert completly in the ignition, goes in until last 1/4in of key. Im stuck, I bought the new lock cylinder but how do I get the old one out? I cant get the key to insert all the way so I cant get it to the "On" position, it will not turn at all. The key that was inserted in error is whole and nothing is missing it seems like there is something stuck. Any help would be appreciated...
