Cubase elicenser key

I’m normally studio based. My Steinberg USB key is plugged into my main computer. However, I have a contract and will have to travel into London to work at one of my clients - I’ve just purchased a UR-22 for my laptop. I have a couple of questions:

  1. Is there anyway I can copy my USB key - I’m concerned that if I lose/damage it travelling I will be unable to work.
  2. What happens in the event I lose the key or it gets damaged? My licences are clearly visible in my account. Is there a way of transferring them?

Apologies if this has been asked 100s of time before.
