Just make sure you have checked and double checked the lockring thread direction before you start smashing at it with cold chisel and hammer. That 1st one looks like you might be better off with a big adjustable spanner. If you have access to a vice, even better. Just grab the flats in the jaws, then you can rotate the frame to get lots of leverage. That's my favourite method.
If all else fails (as it has once for me) you can VERY carefully use a dremel to cut through most of the lockring and then it will just snap off when you hit it with the chisel.
