You can disable any administrator app in the device settings.

I managed to deactivate the screen lock pin only after uninstall of all app with administrator priviledge including antivirus .
I do not know how it works but it seems if one administrator modified pin for screen lock you can not disable ...it is strage for me was quite a hardache .
