I searched existing threads on this, but couldn't find anything... question... According to the owners manual, if you have the key fob on you, all you do is push the button on the door handle to unlock/open the doors. That's great because you don't have to dig out your key chain and click on the key fob. Then what is the purpose of the $495 upgrade to get the Remote Proximity Keyless Entry feature? They are both keyless, right? Is the Remote Proximity Keyless Entry feature just so you don't have to click the button on the door handle first?
