The audio begins with the distinct sound of keys jingling, setting the scene of someone preparing to unlock a door. They shuffle through the set, the metallic clinking echoing softly. Finally, the right key is found and slid smoothly into the lock. There's a satisfying click as the key turns and the door is unlocked. The subsequent creak of the door swinging open draws a close to the audio, leaving behind a sense of anticipation for what lies beyond.
