Jeep Wrangler Problems

Engine Will not Start Due to Wireless Control Module Fault on Jeep Wrangler

Problem Description and Possible Solution

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.

WCMworks intermittently. When I can't get it to start I remove the fuse and reinsert and it will work for a little while and need to be done again. I keep thin nose tip pliers in the jeep just in case.
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.
Just won't start. Lights wont come on. Remote will not open the door. Ran great, parked it, then this.
engine won't start, no click, no other sound while trying to start the engine, dashboard lights all on , no battery problem, the security red light was on, i disconnected the battery cable and reconnect it again then the engine started normally.
i don't know if the WCM should be replaced since the car is still under warranty!
i will visit the dealership tomorrow .
