i have a question on the key ignition........... please help!!

i've got a 95' grand prix GTP

its happened to me twice now.... when i go to turn the car off, the car will shut off but the key gets stuck at the halfway point and will not come out at all, i can crank it over and a few times the car didnt start, few times it didnt... it even would start again' i'd shut it off and it would still do it, lock at the halfway point

first time it happened for like 2 minutes... last night i struggled with it for 10 minutes, started the car more than once, and the car also didnt start more than once, the lights come on and everything but the engine doesnt crank over

still happening.... getting worst, its something to do with this anti lock stuff

thats deffinatle3y a signal for you to get a new ignition. i work at a dealership and i have seen this too many times. that all it is you just need to get a new ignition switch
