Just a follow-up. I called Taylor and they just said to send it in. It has a lifetime warranty anyway and you void it if they find evidence that you took it apart.
I sent it in on a Monday and had it back by Friday and it works perfectly. "Cleaned and lubricated. Works great." was what the slip said when it was returned.
Not the happiest I had to send it in, but I'd be willing to bet my case is a one-off and I'm thrilled with their service!
