Might work but more likely to accidentally push power button. Hollow hole punch used to punch holes in leather or gasket materials is what is needed. Buy set or single hole punch at building supply, or tool supply for cars or boats.
Maybe make one for one time use from 6" long 1/2 inch electrical conduit. Sharpen one end and hit other end with hammer. Protect eyes with safety glasses.
