Adding on to that, if you take a straw (yes, a drinking straw), and cut off about an inch, you will be able to stick it on that small tab you just removed, and put it back in the steering column. It is a cheap workaround for the lock solenoid in your steering column which appears to have failed. I used to have the same problem you are having about 4 years ago. Haven't had a stuck key since though, ever since I used the straw method
