How Can I Get AOSP Lockscreen for Rooted or Non Rooted GS4

I know there are some apks that you can use through Xposed

but it doesn't really load for GS4. Also there are some links on the XDA forums but you have to do some coding with them. Is there any other way to get it or have someone already did it and I just can't find it?

Look forward to a response.....
