Key ignition tumbler

Had a problem with trying to turn the key it was locked and would take several turns to get it to unlock. So I bought a new tumbler followed the directions on the web.
Disconnect battery.
took off column.
pop off the plastic around key insert.
insert key, put 90 ' sharp tool at op hole of housing and slide forward and turned key to start position and pull cylinder out. Well it does not do that, tried every thing. Husband was a mechanic and passed a year ago cannot afford what dealers charge.
also I can drive the car an take the key out. Is there another way to get the tumbler out? Please help someone.
