This utility will help killing the lockscreen when Apple Remote Desktop accidentally locked you out.
First make sure xcode is installed. Then fireup a terminal and run the following commands:
git clone https://github.com/mattlavine/sunshine-ard.git
cd sunshine-ard
clang -framework Foundation main.c -o stop_lockscreen
Running ./stop_lockscreen
should now stop the lockscreen.
