(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.
Cheers,
Your plan has a large fault, the key has to be in the ignition and turned to enable the synchronization of the door Lock/Unlock programming. If the key does not fit then you cannot do this. Fitting his key will not work either as I assume the fob has the wrong chip in it.
To test you would need to use your circuit board in place of his board and then go through the sync process. You could lose a friend if you screwed up his SKREEM.😉
