回复：你好象说的是rekey

if you don't have key, you can still do it.

take your lock apart, there is a piece of metal on the top, you have to open it with some sharp tools, then take the small metal bars and springs out, put your new key in, then fill the small little holes with those small metal bars and sand the metal bar to the surface, make it smooth, then insert this to the outside piece, the fill with another metal bar and springs, and then sell with that piece of metal. I do think I described it clearly, but you can google it. you need some tools. in the case you have six, it is worth to try.

sometime, it is nothing about the money but fun for this kind of work...
