That you to have been able to remove the lock retaining screw, the door must have been unlocked & open. Simply put a screwdriver into the keyhole & twist to 1 oclock or 11 oclock depending on side & push. This lines up an offset lug & will not need any force.

You need key to remove or drill it out. Drill just above the part that turns, that should cut barrel pins. Turn to 1 o'clock & slide out.
