You need to make sure the EZ Keys dll file is being scanned by Cubase. Find the folder the file is in and make sure it is one of the paths in Cubase plugin information. Not sure what OS you are using. The dll file may be in program files vst plugins, program files steinberg vst plugins. Hope this helps!
