Before you tear it apart, test it first, there could be another problem.
It's kind of easy to get to, you have to take off your steering wheel and column cover and on the opposite side of where you insert the key it'll be clipped on to the lock housing, it just pops off. It's a rather complex little switch and I do not advise taking it apart unless you have a spare there to be your back up if it's really bad. It has a tiny plastic push in twist lock that that goes through the switch and is spring loaded and once you are inside there are more small parts, and can be rather difficult to reassemble. Once you have it out hose it down with electrical cleaner and blow it out with compressed air, repeat until clean then squirt in some electrical grease.
If it's really bad, get another one. New they run about $55 - $75, there are at least 3 different ones depending on your year and if you have an air bag or not.
