Theory Of Operation

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK for the secret key information. The repair of this fault condition relies on whether the current secret key in the FOBIK is recognized by the WIN.
