I may have a solution for anyone having this issue. I work for the company that makes the FOBIKS. We have had quite a few warranty FOBIKS returned lately for this issue. The trunk opens by itself, or the doors lock/unlock themselves, even the windows roll down.
After analyzing these parts, we were able to figure out what was causing these "Hauntings".

Here's the issue,
The FOBIK has a rubber mat with the button graphics on it. If you open your FOBIK, the bottom side of the rubber mat has metal discs called "Snap Domes". The sanp domes are what give each button that snap feel when you press it. Each of these snap domes are made of stainless steel, coated in a black carbon paint to give them extra conductivity. When you press the button, the snap dome completes the circuit for that button and the FOBIK transmits.
The issue is that sometimes a small piece of the carbon coating can break away from the stainless steel and get trapped under the snap dome. Even a very, very small piece of this is enough to create this problem.
Because the carbon material is very conductive, and it is trapped beneath the snap dome, it can complete the circuit very easily and make the FOBIK transmit. Depending on which button this happens to, this can create a variety of issues.
If this phenomenon occurs beneath most buttons, the outcome is very predictable but is most annoying when it happens beneath the Unlock button. That can randomly unlock the car, but also can make your windows roll down. Not good if it's raining out.

The FIX is very simple. Just open up the FOBIK, and use a q-tip and wipe both the PCB where the snap domes make contact, and also wipe off the underside of the snap domes. Remove any loose black residue. Once gone, the problem should go away as well.

This is happening to mine also. 2009 R/T

The "snap-dome" fix sounds like the solution to your problem. If that doesn't cure it, I would either remove the trunk light bulb or disable the switch to prevent it from draining your battery.

All is takes is a bunch of coins in your pocket or other keys on the ring while in your pocket to depress the button. Look at your FOB. The bottons on the Challenger fob are raised. Except for the panic button. It does not take much to depress the button and you will - open the windows, open the trunk, unlock your doors. But almost never set the panic mode.

I cant count the number of times I get into my car, sit down and hear the trunk open....

I now carry my keyfob in my jacket or shirt pocket.

Actually I've set the panic button off about 5 times in the past year at work.
