I have a 1996 Beneteau 50 in charter use and the keys to the companionway hatch lock have "gone missing". The charter company could only swap it for another identical lock (with keys) from another boat, so I brought the old lock home to see if I can get it rekeyed. The lock was made by CAS in Italy, but I could not find the model on their website. My local locksmith seems clueless of how to rekey the lock, and BeneteauUSA was able to provide only blank keys. Does anyone have any similar experience or suggestions of how I might proceed?
