Help!!!

I have a set of dunlop original straploks on my nice leather strap, one problem, I can't put the straploks on my guitar without drilling the hole deeper, which I really don't wanna do. What I want to do is take the locking buttons off my strap, but I CAN'T!!!! I had my local music shop install the straplocks on one of my older guitars, so I have no idea how they are installed, therefore I have no idea how to get them off. If ANYONE knows how to get the locking buttons off of my strap please tell me.

B.t.w I have tried about everything i could think of, from turning them for ten minutes straight, to trying to pry them off.

Please help,
thanks.

I don't know what they are really called, but I bet they have those little "slip washer" type things. Looks like 3/4 of a washer that slides across the pin to secure it. Not sure how to explain what I'm talking about....

I saw that, but how do you get it off.

Not really sure. I'd probably just find something to pop it off with, such as a butter knife or something...you might could use a pair of needle nose pliers to get it..just be sure not to bend it..

Alright thanks for the help, I got it off.
