Once you get the handle out, you need to remove the handle bezel. Carefully lever off it's retaining collar & remove the spring underneath it.

Then there's a pin which needs to be knocked out. Once this is out, the barrel will come out.
Make sure you don't lose the sliding locking block when you strip it down.

Are you going to replace it ?
If you can soak it in a penetrating fluid for a while, the wafers should be able to be freed up.

I presume you've tried rinsing it out with WD40 ? I had to do that when mine got full of sand and muck (I also had to do it on the phone keypad )
