That little thing worked like a charm. The pin on the end is small enough to easily allow you to start sliding the keeper while keeping the pin depressed.

I've used a number of things to disassemble this before, but this was hands down the easiest.
Don't know if that will help anyone out there, but thought I would pass it along.
For those that don't know what I'm talking about here's a picture.
