Can widgetlocker be used with an actual lock?

[npark2012]

I really dislike the lockscreen of jelly bean 4.2.1 I want a different more functioning lockscreen but the problem I am facing is that every single lockerscreen replacement is that it's unlocked... no pin or anything. So I was wondering if I can use widgetlocker (preferably pin code) along with Apex launcher. And does anyone know of a way to reply texts from the lockscreen without unlocking the lock?
