It's compatible with XT1052 version 161.44.16 UK retail, so if you have different version and don't want lose your lock screen functionality, don't flash it !!!
However it's working for me well, always do backup your version Keyguard.apk before flashing.
Of course I can make version compatible with any other stock ROM, but I need your original keyguard.apk which you can pull from your ROM guys (system/priv-app).
I hope that somebody like...
Below available versions at the moment (based on yours original keyguard.apk).
