Well it sounds suspiciously like our perrenial favourite, the keyless works!
Instead of attempting to explain things, can I suggest you type "keyless works" into the search area, top right, and browse through the 27 pages of answers you will find. Somewhere in there I am sure you will get an answer.
And if things are still not clear, by all means come back here, and ask again, and we will draft any one of quite a few members who have experienced this same malady (some more than once!) to sort it through for you.
Fortunate it is a cheap Asian, as it will now be in for at least a dial removal, so you are lucky that your skill set is about to improve further.
I'm actually surprised that this one is not part of Toads Noobs guide?
Good luck, and come questioning again, if you need to know more.
