Without knowing for sure what the buyer of the forks has been up to you are somewhat blind until you do know for sure, sorry I know that's stating the obvious but until you do know I don't think you can move this issue forward.
I also think you are in a very difficult situation and unfortunately one of your own making, although totally inadvertantly I'm afraid.
Here is the official eBay meaning of the selling catergory Used.
"Used: An item that has been previously used. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or an item that has been returned to the seller after a period of use. See the seller’s listing for full details and description of any imperfections."
It clearly states that the item is fully operational and functions as intended which of course would extend to the remote lock out.
I do, however, think the buyer is being a bit of ass by not at least discussing things with you before opening a case against you.
One thing I would make sure you do when you discuss the matter with eBay is to advise them to the very best of your knowledge the lock out was operational and you were extremely surprised to be informed that is was not functioning properly. However, you kindly provided to the buyer the method to make the lock out function properly and the seller subsequently informed you that if there was a problem which of course you dispute they "fixed it" or were using the lock out properly and therefore you feel that the buyer has subsequently broken or done something they shouldn't have done to the lock out and is trying his luck!
I don't know if that'll help or not but nothing ventured nothing gained is my view but I suppose a lot depends on what you have said in any e-mails you've exchanged.
A possible way to sort this matter out is to offer to the buyer a full refund based on the reason that the forks were sold with a working lock out and that subsequently the lock has been been found to be defective and therefore not in line with the "used" description of the auction. Get them back and see what the buyer has been upto.
I'd also ask eBay what the situation is if it is clear that the buyer has done something to the lock out they shouldn't have and thus you feel the problem was of their making - i.e. can you counter claim at a later date?
If you do get the forks back, perhaps you should try selling via the forum and then at least you wouldn't get hit by another load of eBay and Paypal fees.
Whatever happens I hope you get a satisfactory outcome.
