If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

Car will intermittently not crank, not start for no apparent reason. It has never occurred first thing in the morning, but at any time once it has been running and is turned off, and then trying to start it again. Thought it was the heat, until it happened on a colder day. Thought it was the battery, installed new battery........old battery tested out fine on load test. Stopped by Chrysler dealership and inquired about it and they suggested it "could" be the W C M . Am waiting for it to happen again so I can disconnect the negative battery cable to see IF that re sets the WCM. Then, I may go replace the WCM at a cost of around $250.00 including tax and labor and part.
2007 Chrysler seabring it cranks but won't start up it does this only after driving the car... If the car has been sitting for several hours or overnight it starts no problems but if I drive it more than 15 miles turn it off and try and crank it again it doesn't start. Sometimes it takes 5 or 6 tries to get it to crank

Car wouldn't start and key fobs would not unlock the doors. All other power worked (radio, lights etc). Had it towed to dealer. They reset it by pulling fuse and reseting computer. Part on back order so waiting for it to be replaced. Glad I had an extended warranty!!
