I guess you've never had those type of key's fail on you and you are stuck and can't get into your car.. It has happened with my mothers Mercedes and it ain't fun let me tell you..
I thought all of them had a backup regular key built in
I know some are made into the remote. Also aren't the remotes passive?
-No need to pull out your key
-You can start your car faster. When your in a hurry or on the go, its nice not to have to fumble with a key.
-some remotes can receive service data from the car, which can then be read in the service department without the car being physically present.
-better for drivers with disabilities that impede their ability to grip and turn a key, example: arthritis
-No more keys locked in the car
As long as there is a backup key, what are the disatvantages?
I mean if it had a regular key and the push button, would you still put the key in to start it?
The only disatvantage I could see would be cost and it could add a few pounds.
I don't think it will make it onto the 2009 Camaro but I would love have it on mine.
I know some people just wouldn't like it at first because of being used to doing it the other way for so long. Just like some people I know don't like auto headlights or auto down windows. The better designs of those include a way to disable those fetures. Some auto headlights and auto window down allow you to opperate them manually for those that would rather opperate them manually.
So IMO if they can keep the cost down and make it in a way that allows those who still want to put the key in to do so, then why not?
