Well the door handles (hardware) for the system you describe are definitely different and would be needed if you don't have them. The 'touch' sensors are integrated into the back side of the door handles. From your description it does not appear that you have CA. There would be a myriad of hardware besides the handles that would need to be retrofitted at a high cost. So simple coding would not be a solution. You would be better off buying a car that already HAS CA...
