My Nokia 5310 is locked

[Jymmy0503]

Hi,
My Nokia 5310 is locked. That happened few days ago. I restore all the factory setting and since that my phone is not working.
When I start my phone a I've asked to create a new code and to confirm this code after confirmation the phone remains locked and the key board is not activated.
Can you please help me out?
Thanks
Jules

I believe all Nokia handsets use 12345 as default security codes.
Try it, but I'm not sure.
