A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.Google+

Went to work and it was fine. Left work and would not do anything
all dash lights come on, radio works, headlights on, but motor will not crank, tried removing IOD fuse to reset WCM (this worked once before) not this time. Tried to disconnect battery to reset and that did not work

Car would not turn over, all dash lights on. Replaced starter & battery. Not the problem. Took back to dealership and we were notified it was the WCM.
