I recently puchased a 2012 SX4 Crossover that included the tech package. I was under the assumption that the 'Smartkey" was included. I saw that one of the SX4 Crossovers in the showroom had a button ON the drivers door handle. In addition to the lock/open the door with the FOB in your possession alllyou need to do is perss the button on the door.
My car has keyless entry but no door button and you have to start it with the key. The one in the showroom needed no key to start it. My car has the fog lamps, heated seats, floor mats, Garmin GPS on top of dash and bluetooth but no keyless start. My salesman shrugged his shoulders-he is very good at that and is an exceptionally good liar.
