You need to separate them with your index fingers and thumb. Once you do that get the one end in the groove and use a small screw driver to push the coil in. There is a company that makes an installer just can,t remember who they are. Your fingers will be sore.

Pull it apart about 1/2" like a slinky. Start one end and work it around.

Put the end in the groove,move over about 3/8" inch at a time and push down toward the groove until the complete lock is in. Then you do the second one the same way,just make sure the first one is down all the way.

Once you do one...the rest will go fast.
