I think it&#x27;s fair if a vandal uses a copied key to enter the office and pee on the rug, then the company should cover the costs of changing the locks, but the vandal is responsible for the damage to the rug. Changing the locks is a direct consequence of the company&#x27;s failure to collect the keys (and needs to be done regardless of what if any vandalism has taken place), but the follow on damage was not caused by mere negligence or happenstance.
