The little wire you see is a hall effect switch. If it has come off and your lock cylinder is still salvageable, you may be able to solder it back where it goes. If this is not the case, try a salvage yard for the parts. You may be able to swap the out with a regular lock cylinder, you would have to disable the sentry system too. I'm not real sure you can't just get the lock cylinder without buying the whole column.
