About Keys :
I offer 2 types of keys - for 24hr or lifetime.
All the keys (Ultimate, Vanguard) are locked to both Activision and Battle.net accounts, but not HWID locked.
I do not sell keys for use with multiple accounts.
I do not perform keys replacement, upgrades and reset.

24hrs key:
You can use it unlimited times for 1 account for 24h from 1st activation
LifeTime key:
You can use it unlimited times for 1 account as long as your game account exists, change whatever whenever you want, after each game patch or regular update, by paying only one time
