Bitdefender Keys help and 2017 upgrade


So, I still have a subscription of 269 days for internet security 2016 with 2 product keys. May I please as what would happen if I activated another key and will it extend my subscription rather than null my 269 day subscription? Also, I've already upgraded to the 2017 version in my computer so what should I do about it. Any tips?

    If the keys are the same product and same number of users (devices) they will merge and extend the number of days.

    If you have mismatched number of users or its a different product I would advise contacting our support team at
