Your car has the Passlock security system, which is notorious for this. You can find various at-home fixes by googling “2007 Impala passlock” but they may or may not work. You may end up having to take it to a dealer and paying them a good chunk of change to change out the passlock system. In my opinion this should be (yet another) GM recall, but isn’t.
