Ideas on how to pull ignition switch tumbler with no key

I have a good ignition switch with a tumbler already in it, however I have no key that fits the tumbler so I can't turn the tumbler to the correct spot to be able to push in on the release button. Any ideas how to get it out?
There's a variety of ways to get the lock cylinder out of a '69 ignition switch. I like to pick them into the ON position when I can. Sometimes that works, sometimes it's too stubborn. A '69 switch and lock cylinder are unique. No other year uses those parts, so be careful or that could get expensive. If the lock cylinder hasn't been re-pinned, you can have a key made by the 3 digit code stamped into the top (when mounted in the dash) side of the switch body. A locksmith should have a manual to look up the proper cuts needed to make the key. Another way that sometimes works, is to take a door lock cylinder (usually the passenger side is the one most likely to be original) to a locksmith and have them make a key that matches the pins in that lock. If the ignition cylinder is also original and matches the door cylinder, the new key should work in the ignition lock.
