i give my sx1 to my girlfriend and she put the phone code too many times wrong and know the phone asks for a code and it is locked. Can some one help me?

Is it asking for a lock code or a PUK or PUK2 code?

If a lock code, and you don't know/remember what it is, take it to a Siemens service center.

If a PUK or PUK2 code, call your operator (who issued the SIM card).

PUK = Personal Unblocking Key.
