How do I install Avast Premier back on laptop without a product key?

I have been searching for a product key to record to use on my laptop when I get it back from getting a new hard drive. I found my customer number and when the program expires, but nothing on a product key or activation key. I bought this for 3 years and it doesn’t expire until 8/7/2017. Can anyone help me?
