Help replacing ignition key tumbler in 97 Toyota Tacoma?

My key tumbler is worn out in my 97 Tacoma, I ordered a replacement, but now I can't get the old tumbler out! I can't turn it to accessory, so I drilled the little button tab below to release, but it is stuck fast! No amount of wiggling, WD-40, or more drilling seems to work. It's like there is a second catch somewhere holding the part in place. I've watched every video on YouTube I can find, the tumbler should just pull out at this point, but there is obviously something still holding it firmly in place.

It isn't the outside ring, all housing around the part has been removed... I don't know what else to do.

Thanks so much!
