2000 Dodge Neon Ignition Switch won't turn

I am having a continuing problem with my ignition switch. From time to time, the ignition switch will get stuck, and it takes repeated attempts of moving the key in and out before it will turn. I have tried moving the steering wheel as I turn the key as well as making sure the Transmission is completely in the Park position while also turing the key, to no avail. I really had trouble with my ignition this morning, and am wondering what the problem could be, and what I can do moving forward (hopefully without having to take it somewhere to get fixed). Can you help? Is this something I might be able to do myself? Any troubleshooting techniques I can try? Please help...
