Confirmed: The only way to do a working remote on Chrysler Crossfire right now is the KR 55. The Autel XP400 PRO can write the transponder no problem, A key to start the car and be mobile is better than to walk is it not.
Here comes a review of 2005 Chrysler Crossfire AKL using Autel and KR55.
Desoldered MCU and read the bin file with apb128. Was able to program a flip remote with the KR55 using the bin extracted with Autel IM608. Then resoldered the MCU to the SKREEM.
Easier to use the Type 1/2 adapter and just cut/repair the trace for the KR55.
