I'm having an issue with my keyless entry, sometimes it works flawlessly, then other times it will not unlock or lock when I press the buttons. When I stick the key in the keyhole to unlock it the alarm goes off. I've replaced the battery with new ones and that didn't seem to work, any ideas?
Check your IOD fuse and make sure it's seated good. I've heard others had this problem, and had something similar one time after doing a MyGig reset by pulling the fuse. I reseated it again, and no problems since. Since you have an 09 ( if your profile is correct) it might be worth a remote battery check as well, could be low enough to be intermittent, and they're only a couple bucks for a new one.
This happened to me once randomly; Locked the doors and went into the store. Came out and keyfob wouldn't unlock the doors. So unlocked manually, alarm sounded, started Jeep, alarm stopped. When I got home, keyfob locked/unlocked the Jeep fine.
A few days later I was scheduled to take the Jeep in for misfire/head replacement (2012). When they were checking the codes, they noticed there was also a code for the wireless control module failing. So they replaced that too while it was in the shop.
X3 I think when you lock with the key fob you have to unlock with it also or the alarm will sound. (Then you have to start the jeep to stop it.) I found that out late at night at a campsite trying not to trigger the "illuminated approach" headlights to come on when unlocking. (I don't have EVIC wheel controls so only the dealer can disable that feature. )
I have it where it unlocks all the doors on the first key fob press. I like that way better than the default having to press twice to unlock the passenger/gate doors. It's near the top of this post on how to do that. http://www.jk-forum.com/stock-jk-tec...isable-228859/
My Wireless Control Module was replaced at around 11,500 miles.

My favorite quote from the press release.. sad but true: "Chrysler claims its products, especially the Jeeps, can handle all sorts of terrible conditions, churning through muddy swamps, climbing mountains, and crossing rivers. Turns out they cannot even handle a car wash."
I recently changed the batteries and installed new ones. Just check all of the IOD fuses and all are installed/seated correctly, its just been doing is every once in a while its not an everyday occurrence. I'm not sure what to do now!
Just had mine replaced yesterday. 12k and it wouldn't start the jeep after double parking to unload. Dealership said the chip fried in the fob. Cut a new key and it seems to be working fine. Odd thing to go bad, but I guess it could have been worse.
I've noticed that when I use remote start my range to unlock the doors is significantly reduced, anyone else notice this?
Yes I do.
These problems aren't new to Jeep. My SRT8 key fob wouldn't unlock the vehicle half the time. There were countless threads regarding this issue and I see my new JK has the same random issues. The dealers couldn't find or fix the problems on countless SRT8's.
I boiled this down to solar flare activity, electromagnetic radiation, distruptions or voids in transmitter receiver signals - things the dealer can't help you with.
Seriously, you should be able to unlock the vehicle with the key without sounding the alarm. I can with my old XJ by turning the key counter clockwise first and then clockwise to unlock - this disables the alarm.
Twice, my JK remote start wouldn't start the vehicle - but it works most of the time.
