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

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.

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.
So the problem started about a month ago when i started my car it started and died about 5 seconds later. Took the key out and tried again and then it ran fine. The problem got worse, to the point where I figured out if I threw it into drive shortly after starting, the car would drive normal. (Knowing these is very bad on the engine). Then after a couple weeks the problem completely went away, until one day it left me stranded in a parking lot. My girlfriend came to pick me up, get it towed, etc. Then while we were trying to push it into a parking stall, she put in her spare key and the car started with no problems. Put my key in, started then died, hers back in and it ran fine. Okay we solved the problem right? Bad key whatever. Until today when it started the problem again with the "good" key. So confused. Tight on cash/trying to figure this out on my own if possible.
Everything works but wont crank
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.
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!
Attempted to start car this morning and nothing. Dashboard lights on, power windows work. Attempted to jump the car and nothing.
After reading prior posting on this site I now believe I am experiencing a similar wireless remote module fault

Tow driver also believed this may be issue. We attempted to start car with spare key with same results. Key inserted into the driver door and panic alarm was activated.
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.
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. RI-Effing-DICULOUS.
I have a 2002 Jeet Liberty. Intermittently will not start. After about anywhere ranging from 5 to 30 min will start. Thought it was solenoid in starter, changed it, thought I was good to go. Next day happened again. Read several forums on this problem. Not looking good.
I want to report that my car had this problem even after many attempts to fix it at the dealer. Finally it has been fixed, and I will tell you what they said was the problem in my car. The SENSOR that tells the car that it is in PARK….. was not working, so the car would not start at random. After changing the starter etc, which didn't work, they fixed this sensor and it has worked so far. So if you are having the problem with not starting, ask them to check this part. Good luck! I don't think I will buy another jeep, even though I have had 5 or 6 and loved them. This car has been a complete lemon! NOT dependable at all.
Same thing with the jeep just not starting took it to the dealer they said it's the ignition module and that it's 800$ for the the new one, new key and work. Does anyone know if that's what really is the problem?
Has no crank condition. Been to dealer 3 times & the problem continues.
It randomly won't start
Drove the car to the store this morning, back home. Was leaving again to attend church this morning and it would'nt crank! The dash is saying no fuse. The Jeep Manual is no help. Help me please. Did not give me any warnings.
My 08 jeep liberty sport had a total loss of everything. I was in a parking spot in my townhome complex i went and started my jeep with no issue backed it up to the garage to load a few things and shut it off. About 15 minutes later i went to leave and nothing. No crank no lights no ding. I jumped the battery and nothing still. Long story short, i ended up pushing it into the garage (no easy feat for two people) to try and figure out the issue. It was the original battery so i replaced it. Nope. Checked and tested all fuses and relays. Nope. Replaced ignition switch. Nope. Replaced cam and crank sensors. Nope. Replaced ecm/ecu which was part of the problem as one of the transistors/capacitors was off the motherboard completely. Plugged the new one in still nope. I could make it run by jumping relays so i looked at the ignition switch and keylock cylinder. Low and behold that cheaply made plastic part that goes around the cylinder was cracked. Come to find out thats a MAJOR component of the vehicle considering it tells the computer wtf to do when u put the key in. So now i will be replacing the wcm receiver and looks like i will have to take it to the stealership to have it programmed which is what i was trying to avoid. Ugh.
It basically won't start and when u try to start it up it want make a sound and all the lights on the dash board
Hello! I've also been having this same exact issue. I even had to have it towed to the dealership and of course it started right up. It has intermittently been doing this for 1.5-2 years. Sometimes I can just turn the car off and turn the key again and it will start up. BUT there are times where I have to shift the car into drive and then park and then it will work. I think it's not sensing that the car is in park so it won't start. I'm going to contact the dealership today and see if this is the issue, which I'm sure it is. Every other time I've taken it in, they can't replicate the issue/nothing comes up on the computer just like many of you. Like we are making up the problem, right?!
Randomly my car has this issue. Once about 6 months ago so I took the positive battery cable off to reset it and it started right up after putting it back on. Today it happened again same scenario. I have battery power but when I try to start it. Nothing. It sucks
Car is no crank no start. Will suddenly start than die, after leaving key in almost start position car will start. Happens about 1-3 times a month
