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.

My car wouldn't turn on at certain times. When I took it to Jeep they told me that: "the reason for your intermittent starting problem is because the WCM (Wireless Control Module) for the vehicle is internally shorted out causing the vehicle to shut down the computers. To fix this problem you would have to replace the WCM. This repair would cost $842 + Tax." I've come to realize that this is more of a common problem that I anticipating- taking consideration other posts and that my jeep dealership told me the parts were on back order as well. My question, why isn't there a recall? Very much annoyed

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.

Intermittent no start. GC would start using remote but then the key would not be recognized by ignition. Dealer says WCM. Estimate is $800.

Fixed my non starting ignition failure problem for certain after dealer declared they might've gotten it by repkacing the starter harness even though the codes showed a wcm fault. My solution broke my heart but its the right one... 2011 Toyota 4runner.

Runs fine and then I will get in and it won't turn over. Let it set and normally it will work next day. Have had it in the shop twice now. 1st time they couldn't get it to do it at all so they replaced a recalled part from before. Had it towed to them the next time so they could see the problem - still didn't see it - replaced the batteries in my key fobs. Today won't start again!!!!

I lost the keys to my jeep so I drilled out the ignition to start my car with a screw driver. (So remember this). My car died and I jumped it to start it but the security came on so my car starts for a second then turns off. I've tried taking out the security and battery but does not work. Please please please help me

Same as others have written. First started about a month ago when I turned off the ignition & pulled out the fob, but jeep kept running!!! Then got it shut down & wouldn't start, message "damaged key". At dealers for fix "out of warrant of course". Initial estimate $700 + another $280 for fancy glass filled battery!!! asked if battery was dead, or if it could be charged....apparently it's not that the battery is dead, just gives the code that it's dead! Dealer is gonna put old battery in & see if it still cranks!!! German engineering folks!!!
Four times my 2010 Jeep Grand Cherokee LTD has failed to start. When the key is engaged all of the lights "light", but it won't start. I've had AAA tow it to the same shop 4x since December of 2014. We've replaced the starter because the mechanic thought it might have a "dead" spot. It happened again.. When it got to the shop - it started every time, no problem. On January 9th it happened again and it was towed to the mechanic - it started while at the shop.. every time and they drove if for the weekend w/o a problem.. again a month later it was back in the shop.. where I had the key's re-flashed. It wouldn't start last Tuesday, towed again. Now its at the dealer's being evaluated for a faulty ignition module.

This happened to me 2 months ago, so we had the WCM replaced and the key reprogrammed. Well, it just happened again 2 days ago, and they had to reprogram the key AGAIN. We will see if it happens again!

I had previous non start issues that the dealer fixed while I wait for the parts from the fuel pump relay recall. A few weeks after the fix the car stalled while I was reversing. This time they are telling me it is the wireless control module and I have to pay $360.00 to replace it.

I experienced the exact same problem just two days ago. I was hoping to just get my starter replaced, but unfortunately they diagnosed the problem was more than just that. The wireless control module replacement part plus a new programmed key is going to cost $800.

I had all of the same problems and the blower motor fuse was the problem!!! ITs because of the grounding it has
When the key is turned to start the car you hear a click and a sound as if the starter would try to engage but the engine will not turn, changed the starter relay and nothing happened, still clicking. After a few tries the GC would start and continue normally. Took it to a repair shop, battery , charging system and starter checks fine. Will continue monitoring.
module transmitter failed--exchange part = $392 plus $191 labor--can't even give me a date on when exchange parts come in--could be without vehicle for a week. I I think I am going to trade it in.
I could not start my car and through it was a bad battery, I replaced the battery and could still not start my 2008 Jeep Grand Cherokee. I then had the Jeep towed to the Dealership thinking the Key Fob needed to be reset. Nope.....it was the WIN module that needs to be replaced. This is not the first time hearing this could be a problem. I am very angry that I am now paying 800.00 to have the part replace.
