A day later, Mrs. Malfoy had owled Hermione that she needed a few more days to get hold of Draco’s spare keys. This was when Draco chided himself for having excessive protection for the keys. To prevent others from stealing information and experimentative potion recipes from his office, he had kept his keys in a box with a portrait. The box would only be unlocked when the correct password was given. Brute force would only result in complete destruction on the box and the keys. He had not told anyone of the password, so even for expert spell breakers, they would need at least two weeks to make a breakthrough.
