To help we'll need to know a few more things:

- Have you had this working before at some point in the past?

- What is the error that you receive?

- Is it complaining that it can't find the SX-Key?

- You can usually program with the resonator plugged in (can't debug with it in).

- If you have an oscillator then that must be removed for both programming and debugging

- The SX-Key gets power from your SX development board.  Does that have an adequate supply?

- Is this the Serial SX-Key or the newer USB one.  If it is an older one then are you using a Serial to USB adapter?

- Is the key plugged in backwards (had to ask)

I've been using one of the SX-Keys for quite a while and every time I had a problem it was always something other than the SX-Key so far.  Double check everything first before assuming the Key or the SX chip is bad.
