In my view the Bible is to be believed (which is a pretty big *if*) then even the greatest demon of all Satan is susceptible to being bound with chains and sealed in with locks1, so it shouldn't be much of a problem since humans possess all manner of chains to bind a lower ranking demon so we can study what a demon actually is for ourselves.
1 From the NIV translation Revelation 20;
"And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain. 2 He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years. 3 He threw him into the Abyss, and locked and sealed it over him"
From the NWT (Jehovah's Witnesses translation);
"And I saw an angel coming down out of heaven with the key of the abyss
+ and a great chain in his hand.
2 He seized the dragon,
+ the original serpent,
+ who is the Devil
+ and Satan,
+ and bound him for 1,000 years.
3 And he hurled him into the abyss
+ and shut it and sealed it over him"
