Some shortcuts are not honored by macOS (Ctrl+Shift +Escape, for example).

If you find that the default system shortcut tool doesn't work for you, you can add your desired keyboard shortcut using BetterTouchTool.

This way you will be able to lock the screen with the default shortcut as well as your pre-defined shortcut.
