I was able to get a replacement lock and extra set of keys from Beneteau for my 361.I just came back from the local True Value Hardware store.
I already had a Taylor key that worked, with "41RB" in a circle. The other side says "fits CG22,1041E".
My other key (2006B323, OEM?) said AU-411, made by Select.
I also had, and just got 2 new ones, "ilco (USA)" number 997E, Y52. This was the TVH standard line of blanks. Just be sure to line up the shoulders of the key. Yes, it requires cutting off alot of the blank, but the new ones work.
