Love the starting/locking feature and of course the best feature is rolling the windows down..although I've also drove away without my key fob before. The one problem with my key fob is that it's on a..let's call it a "janitors set of keys" I have about 20 keys (bulky) it seems so I always throw them on the passenger seat or try to remember to put it in the cars fob vagina
. , but I always end up forgetting there in the car. Lol I think smart keys benefit a woman with a purse more than a man with a wallet..
