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+

Not starting, vehicle security light goes off when trying to start. Not even trying to turn over. Like the ignition has been disabled or something. Then, all of a sudden, it will start. Dealer can't get any codes. I can only assume I have the problem the rest of you are having. I will never buy a jeep again.

Went out one evening to start my 2010 Jeep Patriot, key turned over, engine tried to crank then shut down after 2 seconds. Tried again, same thing, then it just went to blank. Dials and gauges work, including the warning light for "it's an electrical issue". Replaced battery in Sentry remote key fob, no difference. Doors and all options work, I.E. Wipers, lights, door entry, etc.Researched and found out its the Wireless Control Module, based on description of issue. Called dealer about the issue along with the Chrysler Corp. Bottom line is , Bring it in, open up your wallet and we'll let you know when we're through draining it. I'm a disabled senior, that has a very limited income, with many doctor appointments. I don't have the revenue to afford these expensive repairs, the dealer doesn't care, Corporate headquarters doesn't care. I bought the vehicle because I thought Jeeps longevity was reputable. Now it seems they are just another greedy Corporation, only after the money. Sad to see that Customer Service, means nothing to them...Very dis-satisfied with their position, and I see I'm far from the only one, based on the postings here...
My Jeep Patriot has had electrical problems since day one. I had the dealership (Kelly's in Brookville, PA) install an automatic starter. They could not get the chrysler one to work, so then put in an off brand one. My wires under my steering wheel are crazily put together with massive amounts of black wiring tape. Anyway--throughout the years, my Patriot has done crazy things--radio would turn off. Wipers would quit. Turn signals wouldn't work. These things would be temporary, and I never took it to get it fixed. But I think they screwed up the wiring with the installation of that car starter. Now--since my warranty has expired, I have this stupid issue with the WCM (wireless control module. It is exactly what everyone else describes. I am just a "woman" but it infuriates me to think that this is an actual problem of the Jeeps in general. I researched this problem and came to the conclusion of the problem very quickly because there are so many posts about it. Now what? I spend 600 bucks to take it back to the dealership to correct it? I am a working mother and can't afford that, or I would get a new vehicle!! It eventually starts, after turning on and off every electrical thing in the car. (It's my TRICK!) but sometimes it takes so long to start that I am late for work and my son gets late for school. It doesn't have a pattern, either. It just started every day for a week, then, it has been not starting for the last two days, every time. It has not been fixed. I NEED IT FIXED. But I just don't have the money right now. Whoa is me, I know. But I thought Jeeps were supposed to last forever. That's why I bought it in the first place. My Jeep is an embarrassment.
Returning home from Canada vacation. Stopped at duty free store in Niagara Falls. When we returned our 2008 Jeep commander would not start. Dashboard readout said damaged key. Tried another key, same thing. We had vehicle towed to US Chrysler dealer, that was July 29, 2013. It is now Aug. 22, 2013, there are no parts available according to Chrysler Customer (Lack Of) Care Center. There are approx. 100 of these SKEEM modules on back order. We may have our vehicle back in mid September. Chrysler rep says Chrysler has no responsibility to me to cover rental, towing or repair costs due to AGE (5 years) and mileage (89,000miles) What a joke!!!
There is no fix at this time, I think it is unbelievable that Chrysler is so unresponsive to this problem.
I would like to hear from any other owners that have had similar problems with their Jeeps. Also if anyone else is on the national back order for this part.

Mine isn't a Liberty, but I have the same problem. I went to unlock it the other night and it wouldn't do anything. I used the key of course and set the alarm off for 15 minutes and everything on dash lit up, but sit wouldn't start. I tried the key in the gate trick, but no luck. I had to call tow truck to take to the dealer, waiting on word how much this is going to drain pocket book! This isn't the only problem I've had with this jeep. Gas spews out when I fill the tank, radio goes off if I roll both windows up at the same time, airbag light comes on for no apparent reason for a few days then goes off, same with passenger seatbelt light when nothing is in the seat, so I have to buckle it to shut it up! Love my jeep, but not sure I would buy another. I also have problems with 4wheel drive shifter breaking with each use, can't afford to keep putting it in the shop! If you can help me with any of these issues please let me know.

Intermittent starting problem sometime turning the key over will help. Also banging engine computer plug will help. It always starts, after messing around . I put a bypass switch to the starter solenoid and when no start hit the switch the starter turned but no start. I guess the starter and ignition go out when it won't start.

My 06 Jeep Commander would not unlock using the wireless key remote...I manually unlocked the car and started it. After driving to the store, I started the car and after 2 seconds, the car shut down automatically. A red dot for the security system alert blinked a couple times on the dash when the key was in the ignition which led me to believe that the problem was the WCM or wireless control module. First get new batteries for your keys; there might be a little screw. After trying new batteries for the keys, DISCONNECT THE BATTERY AND WAIT ABOUT TEN MINUTES; RECONNECT BATTERY AND START CAR. This should at least get you to where you need to go. After disconnecting the battery twice, I tried my keys with the new batteries and everything seems to working properly...Dealers are no fun.
