I thought the circuit board was to send a signal to the chip, to the SKREEM and then allowed the ignition to start the car.

Want to see if the circuit board is universal?Go to a buddy's Crossfire and double click YOUR fob, then have him turn on the ignition with HIS key fob.
Then, try to lock/unlock the doors with YOUR fob; if it works, it is a universal circuit board.
(Don't forget to reprogram his SKREEM to match his fob after the test)
This test would be like reprogramming the SKREEM to match the fob after a battery disconnect.
If someone tries this test let us know the results.
Would try this myself if another Crossfire was available.
The transponder chip in the fob is another matter to deal with.
