I put the wrong key in my 2004 Jeep Grand Cherokee and it won't come out.
I have shaken the steering wheel, yanked and pulled on the key, Looked for a way to remove the key cylinder, still stuck!
Try spraying some WD40 with the straw into the ignition and around the key then use a pair of vise grips on the end of the key and pull.
disconnect your battery, then re connect, sometimes the security locks it in, typical problem
