these are great and served my purpose well. they stay connected as long as you need them and they pop in two whenever you need them too. i put my house keys on one side and my clients keys on the other. that way if i need to i can set them apart and give them to anther aid or whoever is necesary. you could put your car keys on one half and all of your other keys on the other ring. this way you can seperate them so the wieght of your other keys dont mess with your ignition. plus they are easiily decorated. great product and wll made.
