Question about Sony Ericsson K550i Cellular Phone
Did you try "0000" code? It's default.
Otherwise you can also reset the code manually.

K550 doesn't support hard reset by user, only service with special service cable and software can reset the code, but don't worry, it won't be expensive, only few bucks
