When the lift doors closed, Hermione pressed the tip of her wand to the hidden panel. Having the old, familiar wand back in her hand also brought her an immense level of joy. It felt right. The hidden panel slid open to reveal the hole where she was to insert the end of her wand for identification. She'd done this a thousand times with no issues, but for whatever reason, the thousandth and first time produced no results. Nothing happened. She tried again and again to no avail. The lift wasn't recognizing her authority to travel down to Level Eleven.
