How can I erase my security with the ignition like this

The g6 2006 Pontiac key was made brand new for
it from the dealership and was told to program it
by turning the key to the on position for 10 min but
my problem. Is my key won't go all the way in the
ignition  and not able to turn it but if I pulled it back
a lil and use the tip of the key it will turn but won't
start now I was wondering if I can still erase the
security and reprogram it still with the key not
being all the way in the ignition while I'm starting
this process
