Introduction
I developed issues with the FOB not functioning right, needing to be close to the vehicle and in certain areas for it to work. Changing the battery was straight forward and restored its function immediately.
-
Here is the FOB for my Jeep. It decided to finally quit. The functionality became less over the last couple of weeks and required frequent attempts to unlock the vehicle etc.
-
Remove the key by moving
-
locking hatch to the left side first.
-
The two halves where the FOB needs to be split are clearly visible
-
-
Using a plastic opening tool (or finger nail, guitar pick etc.) start at the front of the FOB to separate it
-
Moving the tool along the split line with slight sideways pressure
-
will separate the FOB easily.
-
-
Here is the cleanly opened FOB
-
Bottom half of the FOB contains the CR2032 coin battery
-
Remove the battery by pulling it out of the holder pushing it gently against the spring contacts.
-
Replace the battery following the polarity with the positive side to the body of the FOB

-
Insert wisdom here.

To reassemble your device, follow these instructions in reverse order.

CarComplaints.com Notes: The fourth generation Grand Cherokee took the relatively trouble-free run of the 3rd-generation and flipped the script.
From 2010 to 2011, complaints about the vehicle not starting increased 10-fold. In fact, the 2011 model year is riddled with engine problems and a defective TIPM might be to blame. The TIPM (Totally Integrated Power Module) distributes power to all the eletrical components in the vehicle, so when it starts acting funny so do numerous other components in the car. Orders for new TIPMs were so abundant that parts became scarce, prompting a class-action lawsuit claiming Chrysler ignored this obvious defect.
By 2012 complaints dropped back down by about 80%. Needless to say, if you see a used 2011 Jeep Grand Cherokee on a lot just keep walking.
