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+

Jeep Liberty Engine Will not Start Due to Wireless Control Module Fault
Jeep Liberty Problem
Average Mileage: 68,418 mi (13,000 mi - 190,000 mi)
I had the exact same problem with my Jeep. When I read what the expert said at the top I thought to myself what do you do with any computer when it locks up. RESET it. I disconnected the battery waited a few seconds and then reconnected it. The car started up without hesitation. I took it straight to the dealership. Told them what Repairpal said and what I had done to fix it. They replaced the WCW and I have not had a problem with it since. Thanks Repairpal!!!!!!

Car will not start intermittenly, no crank noise. Dealer says they can't repeat the problem, and the computer does not show anything. I am not happy, bought a new car because I needed a dependable car.
Sometimes when I try to start the car I put the key in and turn and nothing, try again and nothing. Try again and it starts. Doesn't happen all the time. Same thing happened at 30,000 miles and they replaced the skeem module for free. Had the car in the shop and it did it again when the service manager was present. Left the care for 2 days and they couldn't repeat the problem. Computer checked out as nothing wrong. Took it home started for 2 days fine, 3rd day same thing happened again. I think it's the skeem module again they think not. I'm confused.

Every couple of months, with no rhyme or reason, the vehcile will not start even if it was JUST running 2 minutes prior. I checked the battery and the voltage is just under 13v. I assume it's related to this. I saw a link on how to remove a fuse and put it back in 30 seconds later to fix the problem.

I have the same problem with my 2011 Patriot. Usually on a short (5) min trip to the store or something when I get back in the car it will not start. Then over the next few days it will happen again often randomly but will stop for about another month until it starts doing it again for a few days. I took it to the dealership and they said it didn't produce any errors and since they couldn't get it to replicate they couldn't do anything for it.
Also talked to Jeep customer service and they said the same thing. Absolutely no help at all! They even suggested next time it happens to call a tow truck where they would turn the key and put it in neutral and have it work for them I am sure.
How does this get diagnosed? What test do they need to run because I am sick of it!

Bought it used two months ago and the day we brought it home, it wouldn't start in a store parking lot. A passer-by got it to start and we took it straight back to the dealer. They kept it for two days and could not replicate the problem and no codes on the computer, so they said they couldn't do anything about it. It has sputtered a couple of times since then (randomly) but has started until today. Today we can't get it to start even after removing battery terminals, waiting and then trying again.

07 Liberty suddenly won't start. Towed to garage and they could not reproduce the problem. Said it was a loose battery cable. Worked fine for 2 months. 5 days ago it would not start again. I disconnected battery cables and after a minute put them back on. Jeep then started. Today it won't start and tried cables again with no luck. Full power going to everything but no crank. Fuses all appear fine. No diagnosis or repair as of yet

Will not start intermittently. Totally random, but once it happens it goes on for days or weeks. Hitting the steering column works every once in awhile. Mostly sitting and not trying to start it for 15 minutes or up to several hours. This has been going on for the last five years. Just cannot afford to fix it. We were quoted something of $700 to replace it from the dealership.
I turn the key and nothing happens, the engine doesn't crank at all. I have power to everything, the only thing that isn't working is the motor. I disconnect the battery to reset the computer and has only worked sparingly. Sometimes I turn the key and it starts right up only to die right away. This will happen over and over until it won't crank at all. Currently I've been trying for 3 hours to get it to start and no luck.
