If you haven't alreay, read the MIT guide to lock picking.
If you have done that, read it again.
The most common problem is putting too much tension on the lock. What is happing here is that all the pins are being put into the cylinder, and staying there.
You want to split the pin stack at the shear line so that the driver pins are in the cylinder, and the key pins are still in the plug. You will know this has happened when you can lift the key pins a bit and there is no spring pressure on it.
Once all five or six pin stacks are split, the lock will turn.
