Key Insertion into Door

The audio starts with the faint jingling of keys, indicating that someone is sifting through them, perhaps searching for the right one. The sound gradually becomes more distinct, hinting at the person's proximity to the door. There is a brief pause, followed by the satisfying, metallic slide of a key being inserted into a door lock. The sound is crisp and clear, denoting a perfect fit. The key turns with a definitive click, signaling the unlocking of the door. The audio ends with the subdued creaking noise of the door being gently pushed open.
