hi does anyone have a small program that will unlock the keypads on their Nokia 3650 Symbian 6 OS phone?

reason for this is because i purchased Extended Profiles, and whenever i go into my car and plug in my head set, but I always forget to unlock the phone. When i plug in the headsets, the profile changes to a different profile so the tones are louder and no vibrate. Extended profiles allows me to run a program while the profile change, so this is where the program comes in.
