How about a picture of the set up first?

Then a rough wiring diagram of new/old.

If you've got what I think you do, then just transfer the transponder chip to the new key, put the old transponder ring back on the new ignition switch.

Then try to program your key.

If all that fails, take the transponder chip out of the old key. Tape just that on the old transponder ring. Then use the old key to lock the car via the drivers door mechanical lock.

Here are a couple places for info on the ignition switch:
