Gen2s work differently with the approach system and car can be opened and closed without sending an RF signal that can be grabbed and later simulated by thieves to open the locked doors and turn off the alarm.
The system can operate in the same way as the gen1s by pressing the buttons on the keyfob, but in addition it can open/close doors and set alarm without sending an RF signal from the transmitter button in the keyfob while still located in a pocket or purse..........as you approach the car a proximity sensor reads a chip in the keyfob, just like in ignition keys with the embedded chip, enabling the open/lock push buttons in the four handles and triggering the lighted hatch chevron if nightime. The push button ignition is also operated by reading the chip in the keyfob. If you enable auto lock in the DIC, the car will automatically lock all four doors as soon as the keyfob is approx. 8 feet from the car.....if left in the vehicle it will not lock the doors and send a a triple trumpet from the horn. Basically the car is fully operational without ever removing the keyfob from the pocket or purse and the door/alarm RF frequency cannot be "grabbed".
