My door handled snapped off the other day so I have my new one and have started to take my door apart to put it in. Problem is I cant even figure out how to get the old one out. Do these triangular looking propellors have to spin to loosten? I dont wanna break them off beacuse the new handle did not come with hardware. Im not very savy with this stuff so any help would be great. Here is what it looks like.
