My 2002 pontiac sunfire key ignition got stuck and won't turn off I took the ignition out and the part store told me I had to get it from the dealer
Not an exact solution, but perhaps information that might lead to one.
1.Replaced the tumblers? I believe I would replace the entire ignition switch this time. It's my belief that the body of the ignition switch is worn inside, and will keep damaging the tumblers.
2.Do you have a tilt steering wheel? It's best to keep the steering column in straight line when starting the car, then tilt the wheel to where you want, after the car is started. When the steering column is in a tilted position, it puts undue strain on the ignition key switch, and the mechanism the ignition key switch operates, on GM vehicles.
This mechanism, consists of a half moon gear on the ignition key switch, that turns inside a 'Planetary' gear. I used the term 'Planetary', as the gear shape is hard to describe. It resembles an oblong loop, shaped like the number 9, with gear teeth on the inside bottom of the loop. This 'Loop' rotates, when the gear teeth of the ignition key switch, engage the teeth on the loop, and pushes a rod, or retracts the rod. The rod goes down the side of your steering column, and turns on, or turns off an ignition switch, located at the bottom left side of the steering column.
Having the steering wheel tilted, puts a strain on the ignition key switch internals, the oblong loop can break, and/or gear teeth can be stripped off.
Perhaps I have misunderstood what you're referring to as a tumbler.
To me, a tumbler is the guts of the key switch, that the key pushes against. An entire key switch would be way less than that! Was this key switch worked over by a locksmith?
Here, if we are on the 'same page', let me go, and look for a key switch for a 2002 Pontiac Sunbird.
I see! Rare as hens teeth!
Did you get to see your switch? Did it resemble something like this one?

Uses a cable, instead of a rod like I described. Plus Pontiac isn't being made anymore.
Alright. How mechanically inclined are you? Check to see if the ignition switch that the cable, or rod, connects to, has moved on the steering column. If it is located on the column, it should be mounted with two screws. The switch mount itself may have slotted holes, the screws may have loosened, and the switch may have drawn up towards the steering wheel. This would not allow it to be in the correct position, so that a full turn of the key, won't move the switch to the On position.
