Did you get it yet?
Sorry, not sure if I should respond or not. Do you have a photo of it, what make is it. Don't have the keys I'm guessing.
Do you need it to lock again? - otherwise I would say drill it out - I have taken all the locks out of the filing cabinets I own (and the ones I dont that are at work, no need for them there either

- got directors permission to do so before I did this).
