Didn't convince me either.
It's kind of cool to just walk into the car not and not needing to handle a key even to start it, but for me it is definitely not worth the price.
What if you want to be around the car but you don't want it to unlock?
And if you want all doors unlocked, do you have to press a button? If you do, it's stupid. If you don't, what if you just want your door unlocked?
eheh I'm definitely not a fan of new technology when it brings you nothing new! The remote, on the other hand, is a great invention (hard to top)!
