Is a Master Lock combination box good enough for a house key?

The Master Lock 5400D is the most-reviewed lockbox on Amazon with tens of thousands of ratings averaging 4.7 stars, and r/homesecurity and r/RoverPetSitting threads call it 'good enough' for spare keys and pet sitters. Specialist lockpicking subs note these boxes can be decoded by skilled attackers, so they're better suited to low-risk access sharing than guarding valuables.
