Get rid of it? It is incorporated into your PCM, so you'd need a new computer and you'd need to unplug/remove the SKIM module at the same time.
It would be easier and cheaper to just bypass the system. Go to a local store and have them make a non-chipped copy of your key. When you get back home, rip into your steering column. Find a metal piece which is in contact with the SKIM module. Take your SKIM key and duct tape it to that piece of metal so that the metal part of the key is in contact with the piece of metal. If it makes a good contact, the non-chipped key will now start and run your Jeep.
(This is how a local stereo installer used to make remote start systems work on SKIM vehicles.)
