you mean when you put your key in it doesnt want to turn at all?
if thats the case then give the end (where the key goes in) a bit of a tap with a small hammer, then try again. If still no go then remove the trims around it and give the ignition barrel a few more taps around it, lol then shake the steering wheel while trying to turn the key usually works.
reason i say this is because you need to be able to turn the key to get the ignition barrel out
