Try putting a volt meter on the battery as it sits right now. See what it has for volts. If it's below 12, you may have a charging issue. Your jeep may need a fully charged battery to start. If the battery is at 10.8 volts, your alternator may be bad and not charging your battery back to full capacity. After testing the battery at rest, test it again with the engine running. You will have to jump it. Put the tester on the voltage side of the alternator. You should get a reading of 13.8 or higher. If you get something around 12 or less, you will have to replace your alternator.

Forgot to mention that if you have a key with a chip in it, that may also be the problem. I have heard that they can build up static on the key and the computer can't read it. Try touching the key to metal before starting the Jeep. See if that works.......

Thanks, the battery is fully charged. It was hooked up to a jumper box this morning and still would not crank over. I have read about the key issue to, I think that is my last resort.


The only reason I havent went with the Key issue, is I have 2 sets and it wont work with eaither of them. . .


Come to think of it, I think my buddy had a problem with his. I think he was trying to start it with the Valet key. Are both of your keys chipped? If not, only use the one with a chip.

Yes they are both chipped, and I have tried to start it with both of them.


Ok, just did some digging, apparently Jeep has a class action law suit against them for faulty electrical. Here's what I found: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. There was another electrical issue with the TIP module. If you have to replace that it's like $1200 bucks. I think the WCM is about $260 to replace......

Thank you, I will have them test them. It just is weird cause it startes sometimes and my keyless entry works.

I own a 2009 Jeep Patriot Limited with the same issues, the dealer has had mine for almost 2 weeks, claiming parts are back ordered and that there is no recall regarding such as well as that these internal electrical issues are not covered under the warranty. I am paying payments on a vehicle that sits at the dealers service department while I am carless!! Just don't seem right... How do you suggest I get involved with this class action lawsuit?
