Keys that are marked “Do Not Duplicate” or a like, can be duplicated. However, we would need a “Letter of Authorization” from the owner of the key. Also, the letter needs to be notarized and the author of the letter must state who has authorization to duplicate the key and how many keys are authorized and a picture I.D. needs to be presented from both parties. The person picking up the keys will be required to fill out a “Request for Restricted Keys” form. We do reserve the right to refuse to duplicate any keys, for any reason we deem reasonable.
