I need to replace the door handle mechanism because it's stuck. In order to do that, I need to take apart the door handles but there are just two holes under each handle. It doesn't seem that the hole has a screw inside. I tried to put screw-driver inside, it looks like nothing moves then I do that. And a metal round thing around the handle doesn't have any holes to release handles also.
You're going to have to drill a larger hole for the new handles, which should completely encompass the old hole.
Head on down to your local hardware store (or cruse the internet), and look for a door handle installation jig like this Irwin® Door Lock Installation Kit
Example only, these jigs are available from many different manufacturers
It comes with the proper size hole saws to set up a door for modern locksets, and makes alignment of the holes quick and easy. Simply attach the jig where you want it, and drill the holes with the supplied hole saws.
There's a pivot joint in the middle of the knob shaft which lets the two ends rotate relative to each other. You need to get things lined up so each end of the shaft engages just its side of the lockset. That may take some experimentation to get the amount screwed into each of the knobs just right to balance this out, though the cross-pin should help you find the right position.

That little hole that doesn't have a screw inside actually does have a screw. It's an set screw and needs a special tool to remove it. You'll need a set of allen wrenches. You can pick up a set at your favorite home store.
