Thanks MCCRASH, but it didn't work (I received a "code error" message).

 

Do you need security or unlock code?

 

I need the security code. I changed the initial code (12345), and now I can't remember it.

 

Try security mastercode once more.

 

Thanks for trying to help MCCRASH, but it didn't work.
