There should be a small hole underneath where the ignition is, if you get a small probe or really small screwdriver, you can stick it up there and work the key back and forth. This is an access hole to free a stuck key such as yours is. You have to get underneath the steering wheel with a flashlight and look up at it to see it. I know this is the case for '98 tacomas, don't know if they changed it on any other years. If anyone else has a different year, check on it and let him know.
