Why is the key stuck in the ignition switch in the ACC position?

if your pushing in the button to release the key the tumblers in ignition switch bad If you have an A/T, the shift linkage might be off alittle not letting the shifter go all the way into park. Your wheel lock could be keeping the key from turning. If your tires are turned, turn them further from straight while turning the key. I had the same problem and this fixed it.
