Key Battery Low...

After only 5 months of having my 2011 Laredo 4x4, the "Key Battery Low" has popped up in the main display menu. Anyone else have this pop up yet? I expected this to last longer, but I guess the remote start that I use often has drained it faster.
I wonder if it's covered in the warranty...

There are also no screws, or anything to take the battery out, even with the key removed.

Basically take out the emergency key, use it to pry the case apart. The instructions are in the owners manual starting on page 27. Here is a quote from it:

1. Remove the emergency key by sliding the mechanical
latch at the top of the RKE transmitter sideways with
your thumb and then pull the key out with your other
hand
2. Insert the tip of the emergency key or a #2 flat blade
screwdriver into the slot and gently pry the two halves of
the RKE transmitter apart. Make sure not to damage the
seal during removal.
3. Remove and replace the battery. When replacing the
battery, match the + sign on the battery to the + sign on
the inside of the battery clip, located on the back cover.
Avoid touching the new battery with your fingers. Skin
oils may cause battery deterioration. If you touch a
battery, clean it with rubbing alcohol.

I don't know about opening it up. I got a JGC Limited and the power port inside the little console shows a picture of a key and 12V DC as if you can charge the key in that port, but the key does not go in and the port is deeper. Also in my manual it says nothing about replacing a battery.

The 11-13 used a CR 2032. I can buy a 3-pack at the Dollar Tree (Sunbeam brand).

That's a hilarious misunderstanding. Those key icons are an amazing idea though, quite useful to know whether you'll drain/kill your battery by leaving something plugged in.

You can get 10 CR-2032 batteries on ebay for about $5. That's too cheap to not have them on hand.

My 2011 GC kills the key fob batteries every six or so months. There are a couple good you tube videos on how to replace them.

Can anyone confirm that you don't have to resync the key with the car when replacing the battery? I only have one fob for my GC and don't want to buy a battery then find out I can't restart the car since I don't have a second key to sync the original back with.
