What is your question?
Replaced my 2009 5.7 hemi with a 2010 hemi and also the computer, at first I left the old computer in it but the security light was on, swapped the computer for the 2010 and my fuel pump won't come on, do I need to reprogram my key for the 2010 motor and computer for it to work?

Yes, you would have to program keys if you have changed modules. But, worse yet, there's no guarantee the 2010 motor and components will work with a 2009 vehicle. There are too many areas where there could be differences. These vehicles have completely different engine control modules.
