I had the same problem getting used to mine.
Grab the top section boss by the spokes and push the lock up onto it. If you hold the lock against your chest it should push and lock. Then I think most have a screw that fits in place holding the brolly erect.
Personally I think coiling of any line is down to how you load it on your spool....rather than the line itself.
Unless it's on a reel that's not been used for some time.
