See https://www.steamgifts.com/discussion/4V3Cy/humble-bundle-april-2020-humble-choice-5 for the region locks. You should be able to know which one from your friend's country.
TLDR:
China
LATAM/India - Bahamas, Panama, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Venezuela, Colombia, Guyana, Suriname, French Guiana, Brazil, Peru, Bolivia, Paraguay, Uruguay, Argentina, Chile, Ecuador, Antigua and Barbuda, Barbados, Dominica, Dominican Republic, Grenada, Equatorial Guinea, Haiti, Jamaica, Saint Kitts and Nevis, Saint Lucia, Mexico, Trinidad and Tobago, Saint Vincent and the Grenadines, India
RU/CIS - Russian Federation, Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Republic of Moldova, Tajikistan, Turkmenistan, Uzbekistan, Ukraine
Turkey customers should receive a ROW key but instead receive a key that they cannot activate (either the LATAM/India one or the RU/CIS one listed above). source
Everyone else: ROW

its probably for eu or na since the most of hb keys are if restricted are from those countries
so you should change you region country using a vpn wont work cause it should be activated on those regions
i mean if all your other games are open-region
thats what you can do , since you dont know anything about the key but you should ask from him first maybe he knows

I have a Hitman 2 key but this doesn't work in my country and I don't know which country it is for. I wanted to trade but no one is giving row key for a locked key. Now what should I do? Should I use a Vpn?
