If that functionality was encapsulated on a smart phone, that would be fine too.
- jjeaff 8y agoMy 2007 vehicle does this just fine. And any signal from the fob require a press of the button. These key fobs use rolling codes as well. So you would need to capture a button press while the remote is too far away from the car to receive it. Then replay it to the vehicle. Of course you still need the key to unlock the steering wheel and of you touch the break without inserting the key, the ignition cuts off. I'm not sure why we are going backwards in the security department here. Seems like a lot to give up just to not have to stick the key in or press the unlock button.
