It's extremely hard to get it back in and properly working when the spring had unraveled. But I have done it. it takes a lot of time patience and many times of failure to get it right. I usually wind it up out side of the case. Just put on eof your fingers on the inside and just start winding it back up. It takes time and do not wind it up to much as your finger will get stuck and you will not be able to get it back out until you unwind it again. Then once you wind it up then it's all about skill and luck. There are a lot of things that you have to pay attention to to get it to go in that little slite that it need's to slide in.


Good luck and I hope this helped.
