It seems we recently had a similar discussion on this? I am not as familiar with Chrome,as I am Internet Explorer 11. Have you tried clicking on your Chrome Icon/extensions/ and enable? Did you install Safekey on your PC first/Create an account? I think there are certain steps to take in Chrome.
Hopefully one with more knowledge on this particular subject, will pick this thread up and assist further.
Maybe this can help: How to install SafeKey on a PC or Mac
Instructions for installing Safekey on a Tablet: How to install SafeKey on a mobile device or Kindle Fire
Also Technical Support is available 24/7 (Free) Via Chat/Phone is quicker.
All the best,
