When a key gets stuck, forcing it can bend the key or break off pieces inside the lock, while also wearing down the delicate pins and springs that make the lock work. Instead, try lubricating the keyhole with graphite powder or silicone spray, wiggle the key gently while pulling, or use a pair of pliers to apply steady, even pressure. If that fails, call a locksmith before you cause expensive damage.
