Hey all,

I posted this in the generic trouble shooting forum, but after no responses I realize this is may be a better location. Sorry in advance for the double post.

I have an issue I am hoping for your insight into. I have an intermittent issue with my 2012 WK2 with the 3.6. Now and then, I will have a starting issue where the engine will fire up, but immediately cut out and the red security light will blink on the dash. Normally, if I pop out the push button and start with the fob in the dash, it will work. However, sometimes this doesn't even work and I just need to let it sit a few minutes and try again.


I've brought it to the dealer, and they couldn't get it to replicate the issue, because as I said this is very intermittent (sometimes it can happen several days in a row, sometimes it goes weeks without happening). The only thing they noted was that there was a stored code for invalid key (I think - something like this) in the system.


I've tried replacing the key fob's batteries, and I've tried using both sets of keys. Neither seem to solve it.


I've replaced the external fuel relay that was installed by the dealer due to the TIPM recall. This did not fix the issue.



Does anyone have any other good ideas I can try?



Thank you all!

This is how I've seen a Jeep respond to an invalid key. Either immediately post a message in the evic stating invalid key, or starting the engine and within a second shutting it down then the message pop up invalid key.

So it sounds like its the key system that is going on the fritz for you, the wireless node or antenna perhaps?

Thanks Mongo. Do you know if documentation is available to troubleshoot the node or antenna? If the parts are inexpensive I'd probably go ahead and just replace them, but the issue is so inconsistent it is hard to tell if I actually fixed the issue until it happens again.

Mine is at the dealer for this exact issue. They are stating it is the wireless ignition module. It's gonna run about $850 to replace it. I'll keep you posted on the outcome. We should have it back today hopefully.

Hi Swilke,

Thanks for the note. Please do reply to this and let me/us know the outcome once the repair has been made.

We got our Jeep back today from dealer. They had some trouble programming the key to the new WIM so it took an extra day. No big deal though. So far so good. $866 for the WIM module and they threw in key since the old one wouldn't reprogram.

Painful but what can you do. I'm used to fixing my own vehicles but the newer models make it difficult with all of the wireless options and technology. I'll keep everyone posted. Hope this helps others who may have similar issue.
