Maybe try a little bit of heat. Mine went out on me about 800 miles away from home. We found if we twisted it to the on position VERY slowly we could find a spot where it would be on. I would just keep the key in that spot and made it all the way home. I found one on Ebay and just swapped out the bottom as was mentioned in the other thread. Then you don't have to worry about the key and the security system.
