Does a gun case with just latches count towards the Firearm Safety Device Tax credit?

I saw one thread 8 months ago without a clear answer so I wanted to ask to make 100% sure. I was looking to purchase a Pelican case with the intention to use that to qualify for the tax credit but wasn't sure if it fulfilled the "designed to be unlocked only by the means of a key, etc..." line and haven't found a clear answer online.

I was going to purchase some padlocks along with the case as well. Would those also count towards the credit?

Any advice is appreciated!
