Re: Key fob not detected

Don't know if this applies to the above problems, but, as stated above, the key fob is also a RFID device in the 2014 JGC. This from the manual:
"NOTE: In case the ignition switch does not change with
the push of a button, the RKE transmitter (Key Fob) may
have a low or dead battery. In this situation a back up
method can be used to operate the ignition switch. Put
the nose side (side opposite of the emergency key) of the
Key Fob against the ENGINE START/STOP button and
push to operate the ignition switch."

There are 2 parts to the fob. One is a RF transmitter that will work the doors, and locks. Sounds like yours works fine. The second part is the NFC chip that interacts with starting the vehicle. Both parts need to be programmed. This is why you can still start the Jeep with a daad battery by holding the fob to the start button and pushing. If yours won't do this or any other start function, then the NFC chip is not programmed. NFC chips are the same chips in cell phones that allow electronic payments by swiping your phone. It only works short distances - usually less than 6 feet.

Since you need to physically push the start button with the fob, I believe this is an RFID chip. The separate NFC chip is for the normal start button function. Not sure if the RFID chip needs programmed separately or not. Lots of electronics in the fob, hence the high cost of hardware and programming. More on the difference between RFID and NFC here: HowStuffWorks "What's the difference between RFID and NFC?"

So I tried to push the button with the fob (did not take the "push to start" button out) and it still did not work. The truck still doesn't recognize the fob. At this point, can the dealership do anymore programming (to the truck or fob itself ) to get the truck to recognize the fob or will I need to just buy a new fob from them?

Gold!

You are not meant to push the start button with the key fob. You are meant to take the push to start button off and shove/turn the key fob in the key socket like a conventional key, only plastic. This should bypass the proximity you would hope? I guessing it won't though.

This is how the Benz are.

How exactly do I pull out the button and will I be able to put it back?

Slip a credit card from the bottom gap of the button like your gonna steal the car, jokingly. But yes, use a credit card so you don't scratch the panel.

It's in your manuals..

You do this to by pass the battery flat key fob if you need to start the car. Obviously the manual fashion.

If its a used car, try calling the previous owner to see if they have got the spare key fob. If you have memory seating option, you want a working keyfob that the car recognises.

I forgot to ask, you do have a pre 2014 rite? As all the above is relating to pre 2014, as there onwards the push to start button is fixed.

It's a used 2011 overland....the dealership claimed they tried to reach the previous owner but couldn't. Strangely enough, he left all of his pics (over 200) on the hard drive! Popping the button off sounds easy enough, I'm more worried about getting it back on!

Just do it, I'm curious to know your outcome. Its 1am here.

Yes it clips back on. Its just a bit of plastic, not a real physical button. You'd be surprised.

I'm not sure about popping off the start button. I would check the owners manual first for a 2011, before you cause damage to the button. I know that on the 2014, the button is not meant to pop off.

The fob has a chip in it that when the battery is dead, you hold the fob up to the start button, and press the start button with the fob for the jeep to start. The premise is that even without a battery, the chip emits enough of a signal to start your jeep this way.

Like I said, the fob need 2 things programmed. Your dealer already programmed the RF transmitter, now they need to program the chip. Go back to the dealer, and have them re-program the fob correctly.
