Phone was lost, then found, but i forgot my lock pin on phone

I lost my phone and quickly sent a lost command out. I then found it a week later and i forgot the pin for my locked phone. My phone has no internet service becaue i have an application that turns it off to save battery so the found command doesn’t work…I need to know how to get that code or if avast can email it to me.

The “new” PIN is temporary as far I know. You need to use your own, regular, PIN to unlock the phone I think.
