In your case use a single wire and insert it down into the slot.... it should go in about an inch and a half. My 300E requires the tumbler to be in position 1 not 0 as yours is. Do everything possible to get your slot lined up... insert the wire....as thick as possible so that the sides of the wire will release the tension spring and then pull out the tumbler.
I used a 4" grinding wheel with a steel cutting stone to cut out my housing.... made two cuts ... one at about 4:30 and the other at about 7:30.. then poped off the black housing and then temoved the tumbler.
