Key FOB Recognition Issue (Key not detected)

When I am using the push button start functionality and have the key-fob in my pocket, sometimes when someone leaves my car and closes the the door a message pops up saying the key is not detected??? I have to turn the car off and back on for the message to disappear. This only happens after the door closes, and the door has to be closed rather hard for it to occur. My only guess is that the impact from the door closing is resetting something in the proximity detection hardware/software???

Any ideas?

My dealer told me there is a known issue with a "dead zone" inside the GC where the keyfobs are commonly not detected. It just so happens to occur right about the placement of a right front pants pocket in the driver's seat, which is where my keyfob usually resides. I've seen the message a few times, usually I just take the keyfob out of my pocket for a minute and place it in a cupholder. The dealer thought that we might see a TSB on this at some point when Chrysler can figure out a good solution.

No, I have the only key FOB in my pocket. After seeing the issue I started messing around trying to find out where the "Dead zone" is. It appears to be, for me at least, from the edge of my driver’s seat to the door so if I have my keys in my left pocket the issue comes up. I also realized that I don't have to shut off the car and turn it back on to clear the message, just open and close a door. -- I actually just got the Jeep back from getting the radio TSB performed and I believe they scanned for other updates and reset the computer. I haven't seen the key problem reappear since I got it back....so fingers crossed.

This happened to me yesterday. The key was not detected. I opened the door and pushed the button and Jeep started. Closed the door and message said that key left the vehicle. Opened door again, put in drive, closed door and away I went.

Makes no sense why the key would be detected with the door open and not closed???

I got the message this morning for the first time. I popped in a new battery into the fob and it worked. I checked the voltage of the old battery and it was 2.97 volts, so it don't think that was the problem. Maybe it just needed to be reset?

You can only get an accurate measurement of a battery when it is connected to a load. Even bad batteries will give you a correct reading on a voltage meter if they are not under a load.

Having an issue with just ONE of our two key fobs. (FYI, the "problem" fob has a brand new battery).

On occasion (intermittently), the problem fob will open the door, adjust the seat, etc., to all the pre-programmed settings and then not start the car with the push button, and get the notification "Key Not Recognized".

Any idea why this would be happening while the other fob operates perfectly??

I've had intermittent issues with both key fob's. Put in new batteries an all's well for 2-3 weeks and the issues return. Just took the fob apart, bent the four battery contacts as well as the side contact. Right now it's working properly. The dealer couldn't recreate the problem last month. It get's a little frustrating, especially on a rainy day the the doors won't open by hand or fob.

TSB just requires a simple "flash" at the dealer. Corrected my issues.

Hello I dont know if anyone is still listening or watching this thread but I have a 2013 Jeep GC and also having KEY FOB issues. I get this message allot and the dealership has since replaced the key fob, just one day after they replaced it I remote started the Jeep and my wife and I got in so she could feed the baby. Right after we closed the doors they ignition viewer said "NO KEY IN VEHICLE" and disabled the Jeep. Sure enough nothing would work, couldnt unlock the doors from inside, couldnt unlock with remote or even lock with remote. Took the key fob apart to get to the spare key and popped the push button start out and nothing key wouldnt turn. At a loss here the dealership says they cannot reduplicate the problem. We got this thin in Jan 2013 and I would have to say its been the worst new vehicle we have owned. Its been in the shop more times then our 2006 Honda Ridgeline had been in the 7 years we owned it..

Thanks

Took a few minutes, but I kept pressing the buttons until the Vehicle started, then was finally able to unlock the doors.

The alarms went off because I tried opening the doors from the inside of the car. Since the Jeep locked itself it armed itself too and by opening the doors without them unlocked it caused the alarm to go off but it took a few minutes to get the alarm to shut off. This is crazy though. You pay 40k for something and it should atleast work decently.. IMO

For those of you who had the same issue I did, the fix was the TYPE OF BATTERY. I had fresh energizer batteries that would not work. Someone else mentioned that the batteries were thin and that they need to try out thicker batteries. Harbor Freight was mentioned so I bought a 4 pack and it worked! Hope to save many more this headache in the future.
