All i can remember is this short scene from the movie. A kid is the hero and two grown ups are the villians (not sure what else to call them).

Anyways, the villans are cuffed to something or someone while the kid got the key. Something happens and the key ends up in their food (which i’m pretty sure is beans) so to get the villans free, he feeds them the beans and when they have eaten it all they realize one of them have swallowed the key.

That’s all i can remember. I don’t know if the movie is english or norwegian. I’m pretty sure it’s from around 2000, when the VHS Tapes were still a thing.
