do the 61918 locking hubs lock without getting out of automobile?

I have a 97 kia Sportage which my orignal auto mechinal locking hubs have broken.I plan to replace them with the warn 61918 premiun locking hubs.I see 2 types of these locking hubs.One has gold looking centers ,the other looks the same as the cheaper manual type.What is the difference?What comes with the 61918 locking hubs? Reason why I ask the ears on my original cam are broke off. Does the new 61918 come with new cams?
