Key bought from DIG got region locked, keys inside

Update:
In the comments shows that these keys could activated in India

I bought Several games called Scarlett's Dungeon from dailyindiegame. And the key is no longer available In China, it shows Region Locked When I trying to redeem the key. I checked on steamdb.com and i didn't found any sub which is region locked. so I got confused. https://steamdb.info/app/704950/info/

I tried to contact with DIG asked about sub info twice, But they didn't reply, so I'm thinking maybe I can put some keys here ，If you can provide me the Region Lock information that would be really Appreciated.

Here are 3
