Most euro cylinders have a weak spot where the tread for the fixing screw is. You can easily break the lock by fatiguing the metal until it snaps.
-
There are ways to protect against this, with p. ex. hardened insterts that hold the lock together.
-
Professionals use a tool called a Cylinder Cracker for this purpose. The adjustable clamp adaptor, which features a profile on the inside, grips the cylinder and easily breaks it, even if there's very little overhead (only approximately 2 mm required for high-quality tools) to grab onto.

Remove the handle and faceplate.

To remove the faceplate, you'll have to remove the handles first. The handle is typically held by a small grub screw somewhere near the base of the handle.

If you can remove the faceplate from your side, you can typically see all the screws that you have to unscrew to remove the faceplate.
