With the recent gas prices, theft of gas from your vehicle has become an increasing likelyhood. While a locking gas cap won't stop a dedicated thief it will deter most of them to try and find an easier target. I picked up a locking gas cap from the dealership and had it keyed for the Jeep.

Locking Gas Cap Keying and Installation:
This is what comes in the package. You will need to either have the dearlership key it for you, or find a locksmith to do it. I would recommend the dealership since it is much easier than trying to find a locksmith that can do it correctly. Lo
The dealership will key the lock cylinder for you. They insert crescent shaped pieces of metal into the groves on either side of the lock cylinder depending upon your key code. Sorry I can't show this to you, just describe what it looks like.
Then you remove the shipping cap from the gas cap. It just pulls out.
The keyed lock cylinder will slide down into the gas cap. The two pins on the bottom will align with the two holes on the inside of the gas cap and a small locking tab will engage in a grove inside the gas cap. This is the point of no return, if it wasn't done write, you pretty much throw the gas cap away.

Quick Comparison between the one I purchased in 2007 and the new one I purchased in 2012. They got really cheap with them. Almost Junk feeling.
Remove your old gas cap from the Jeep. The lanyard should just pull out of the housing.
Insert the end of the new lanyard into the hole in the housing.
Finally screw on the locking gas cap, and test it with your key. Finding out that it actually doesn't work when you have no gas would not be a good thing.
