Key fob problems?

Hey everyone. I have searched this forum for answers, but only came up with something similar to my problem. Any help would be awesome.

I always lock my Jeep (live in downtown area) using either the lock button on the remote while the passenger door is open to set the alarm (I always open and close this door last as I have my purse on the seat while driving) or pushing the lock button on the passenger door itself before closing it to lock all doors. All has been great so far until yesterday morning.

My Jeep sat all night long Sunday night (at least 10-12 hours) before attempting to get into it to go to work on Monday morning. I pushed the unlock button on the key fob as I usually do, but nothing happened. I pushed it again, and still nothing. I unlocked the passenger door with the key to throw my purse on the seat, and of course the alarm went off because I had set the alarm the night before. I then used the lock button on the remote before closing the passenger door and it worked (all doors locked). The unlock button worked as well to unlock the driver's door with one push and the passenger door with a second push of the button after testing it. Another thing is when I started the Jeep, I noticed that the clock had also reset (time was 6 hours slow) and my ET time on the instrument cluster had reset itself as well. The Jeep started right up and ran just fine though with no problems.

I drove to work, parked the Jeep, locked it with the remote lock button while the passenger door was open, and closed the door. Worked fine. When I got out of work yesterday afternoon (again after the Jeep had sat for several hours), I attempted to unlock the Jeep with the remote unlock button and again nothing. Same exact scenario as that morning. I had to unlock it with the key. Upon getting into the Jeep, I noticed that both my clock and ET time were reset again. I got in and drove home and stopped a couple of times along the way for short errands (grocery store) while the Jeep sat for approximately 1/2 hour. As usual, I locked it in the same manner when I got out (lock button on remote while passenger door was open), and when I returned 1/2 hour later, the remote worked perfectly fine to unlock all of the doors and the clock and ET time were NOT reset. After I got home, I locked it up for the night using the lock button on the remote as usual.

This morning, I attempted to unlock the Jeep with the remote and GUESS WHAT? Damn thing didn't work again. Same exact scenario as yesterday morning and yesterday afternoon. And my clock and ET time were reset (clock was off by 8 hours this time) AGAIN. Unlocked it with the key and alarm went off. Shut off alarm and tested the lock and unlock buttons, and they both worked fine.

Anybody have any idea whatsoever what the problem is? At first, I thought it was my car battery (because of the clock resetting), but the Jeep starts right up and runs fine so it's not that. I have a habit of sticking my keys in my jeans pocket after locking it, so I thought maybe I accidentally hit a button (or a wrong combination of buttons) to unprogram or reprogram the key fob to the way it is now. However, if the Jeep does not sit for an extended period of time (like overnight), the lock and unlock buttons on the remote work just fine after I use the remote to lock it.

Please help! It's driving me nuts.

I forgot to mention my Jeep is a 2011 and I have only had it for one month. I bought it brand new, so I know it's not the remote battery causing the problem.

Thanks again and Happy Jeepin'!

I don't know anything about the new FOBs, but it could be the cell battery in the remote--doesn't matter how new itis--happens all the time--

My '08 is still going strong, cause I use it ONLY to unlock--

I never useit to "LOCK" and these little cells batterys are just like the ones in watchs--

I don't know if you can replace it ornot--may have to goto dealer and they will probably replaceit free !!

Good luck

JIMBO

Key fob battery is easy to replace, just pry it open. Car part places usually have a tester.
But I dont think its the problem seeing other things are being reset. Jeep battery starting to go bad?

Jeep battery shouldn't be going bad. I bought the Jeep brand new about one month ago, and there is only 1100 miles on the odometer.

If it is the cell battery going bad, can I replace it myself? If so, does the remote need to be reprogrammed afterwards?

Just pop the back off and put a new one in. No programming necessary. They can be pretty sensitive if you have dropped it or gotten it wet.

Would this battery also cause the clock as well as the ET time on the instrument cluster to reset if the battery is bad?

No. That suggests an electrical issue somewhere else.

Update:

I just went out on my break and tried to use the unlock button on the remote to unlock the doors, and it does NOT work again and clock and ET time were reset yet again. This time, the Jeep has only been sitting for about 2.5 hours since I got to work. So, I thought I would try something different. I unlocked the tailgate with the key, and the alarm went off. I could not shut the alarm off this time because none of the buttons on the remote would work to shut it off (when I opened the doors with the key, I could press any of the buttons on the remote to shut off the alarm). The alarm would only shut off after I got in and started the Jeep up. I noticed something else too that was odd. After getting in to start up the Jeep, I left the drivers door open (I shut the tailgate after opening it). The instrument cluster said "door" as it should, but it also said "no fuse" and alternated back and forth between "door" and "no fuse". What on earth does "no fuse" mean?

The Jeep came with 2 key fobs, use the other and see if same thing happens.
But really dont see it as the problem with the resetting being done.

At this point you have to take it in. Seems like an electrical glitch with the vehicle sensor.

A friend of mine had similar issues with a his 2011 JKU. I don't remember the exact solution, but I remember something about an IOD (Ignition Off Draw) Fuse...

I'd recommend going into the dealer at this point, it's a brand new vehicle, you shouldn't have to deal with an issues like this already.

Maybe take her to the shop and have the tech hook up an onboard computer to your jeep to check for trouble codes. There might be one stored in the computer although a SES light doesn't come on. under warranty I'm assuming so there's no harm in taking her in.

maybe it's something else non physical.....have you taken your Jeep for a therapeutic ride out in the countryside lately??? Down a dirt lane somewhere, off pavement and around some trees and brush??? Perhaps a nice short run through a babbling brook to degauss the horrors of city commuting??? The endless heartbreak of waiting in the sun, motionless there in traffic, while on the distant horizon the call of other "Trail Rated" Wranglers drifts down into the daily grind???

Or maybe it IS the fob battery??? Those cost about $1 and you can easily change it yourself.....before you head for the woods and "Plan B"......

X2, on the IOD fuse, make sure it is in all the way. I'd pull it out wait 30 seconds and push it back in. Had this issue with a new Grand Cherokee, IOD fuse was not pushed in all the way. Pulled it out, waited the 30 seconds, popped it back in and all was good.

My first thought is I didn't know Jeeps had key fobs... or door locks. Since you have the resetting thing going on I can't believe it is your fob and it sound like some others may be steering you into the right direction. I say take it to the dealer and let them figure it out.

Otherwise I would suggest to learn the piano, snow sculpting and plan an armored car heist.

sorry, misuse of word "fob".....the Jeep security ignition- alarm activation battery is IN the key housing itself which is nearly as large as many 'fobs' serving the same purpose.....Since Pat@FieldsJeep IS a dealer his suggestion is more likely accurate.

PROBLEM SOLVED (I HOPE)

Thanks everyone for all of your advice and suggestions. I popped my hood yesterday afternoon and took a look in the fuse box. Well, lo and behold the main fuse (IOD) was not plugged in all the way so I plugged it in the rest of the way. I locked the Jeep with the remote last night around 8:00 pm with the lock button (to set the alarm). I went out to get in this morning around 7:30 and the remote to unlock it worked!! I locked it at work around 8:30 am today, went out around 11:30 am to check it and the remote still works!! A few more days of the remote working every time I use it and I will be totally convinced that the problem was definitely the IOD fuse.

Thanks again!
Happy Jeepin'!

Fantastic! I'm glad you were able to get it figured out...

Hopefully your Jeep will behave itself from now on ;-)

This happened to me a week or so before Christmas same exact symptoms and has never happened since. I had the Jeep in for service a month or so later and a code was stored that said incorrect FOB. It has not happened since.
