Unhappy Jeep Turns On, then quickly shuts off. Now it won't start at all.

So last night my 2010 Rubicon started up for me, and then turned off after about 2-3 seconds of idling. I started it up again and it did the same thing, about 5 times. After trying again, the Jeep won't turn on at all. The dash lights come on, radio is on and will play, and I noticed the red security right on the bottom right of my dash lights continuously blinks.

After looking through various forum posts, I read that it was likely my key wasn't connecting probably with the wireless control module, which would trigger the Jeep's anti-theft system. Someone mentioned the IOD Fuses could help reset this. I removed the J13, M13, M11, and M10 fuses and put them back in their slots after about 30 seconds each (none were blow, however J13 I was unable to see since there's a clip that seems to keep the fuse locked close to the box). This didn't solve the problem, car still won't turn on now.

The only other thing I have read is that I may need to replace my wireless control module or have a new key programmed.

Does anybody have any clue what this might be...? Or if I'm even close in thinking it has to do with the WCM/key fob not connecting? I'm trying to exhaust all DIY possibilities instead of having it towed to a dealership, for obvious reasons.

Thanks for any help!

It’s likely your key is bad. Do you have another key you could use to get it to the dealer?

I actually meant to mention this in my original post, sorry!

I only have one key (purchased the Jeep used, only came with one). Getting a second key could be an easy fix, but my worry is getting my Jeep towed somewhere to program another key, then it not being the solution, and having to tow to the dealership afterwards. Is there anyway to narrow down to whether or not the key is the problem?

I SHOULD buy a second key and have it programmed anyways, I believe there are some services in my area that will come to your car to program the key in your parking lot. If the WCM is the issue with my car not starting, will someone have a problem programming a new key to the car? I guess that's a whole new dilemma haha.

If your key is bad and you don't have a good second key, you will need the dealer to program a new key. It could be the WCM though.

Most locksmiths will clone the original key to another key. The dealer uses the WiTech/Starscan to program a new key as an original.

Can't lock smiths program a new key themselves? I thought most were able to do the programming as well.

I was going to have a local one come out because I was under the impression they could do so at your location. I was just worried that if I have a locksmith come out, they may not be able to program a new key if it turns out my WCM is the problem. I figure that would cause problems with trying to program a new key.

Most locksmiths cannot make an original OEM key. What they are doing is cloning an existing key.

Call one and ask if they can make a fully working key if the original key is bad.
