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.

It hasn't been fixed yet, but it's a real nuisance! Dealership wants a ton of money to fix. My Jeep is the most expensive and the most unreliable car I've ever had.
