The operator failed to secure the key bit correctly to the stem when attempting to unlock this Rosengrens European Grade 5 safe at a furniture and home furnishings store in Warrington. Without the bit being correctly attached it got jammed in the lock and they could not remove it or open the safe to recover the money that they had come to collect. Using medical grade optical equipment we were able to perform key hole surgery to both identify and remedy the situation with no damage to the safe or key.
