Can not open my phone

I bought Xperia 1 V but I cannot open it because I do not remember my code to the screenlock.

Hi stefhln, Sony created an article for this case to retrieve your phone, here is it:

Mostly, you're gonna lose your data if you didn't back up your data on your Google account or computer.
