Loosing or breaking the security key

I hone a couple of steinberg product like Cubase 6 , Halion 3, mp3 codec and so on and they are all registered to my account my question is what append if I physically break or loose my dongle key ?

Yesterday I was moving some stuff around and almost broke my key so it got me thinking … what if ?

Will the information in my steinberg account enough to get everything back and what will I have to do if it append ?

Thanks

it’s losing not loosing.
