Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you spray WD40 on the ignition switch. This will help loosen the gearing, by then you can remove the key.
Hope this helps and thank you for using FixYa! Have a good one!

My 2004 envoy will not start and all the lights come on..but sterring wheel is not locked asnd gear shift will not move

Lots of possibilities, but based on the information you've given, the most likely scenario is that the battery voltage has dropped too low to engage the starter. It may still be strong enough to turn on dash lights, interior lights or even headlights, but those draw far less power than the starter. That is assuming it is not 'turning over' based on you saying it will not start. If it turns over (cranks the engine) normally, but still will not start, then that is different. The gear shift on most vehicles will move if you have the key turned to the on position, but I cannot be positive about a 2004 Envoy, so that part seems a bit odd. The steering wheel should be unlocked when the key is in the on position, so that part is normal. If it is a battery problem, that could have been caused by some other issue (failed alternator, for example), or could have been as simple as lights being left on. I hope that helps.

Key stuck in ignition,engine will not start battery is hot but no lights

If you are saying the battery is hot to the touch, that means something is drawing high current form the battery and you need to disconnect it before you have a fire or the battery melts. Then you need to find the cause for the heavy current draw. The key is stuck because the shift interlock depends on battery voltage to be high enough for it to work.

These truck are known to have ignition switches go bad and result in strange electrical problems. I would suggest replacing the ignition switch (not the part that the key goes into).

2006 GMC Envoy.. Changed the battery, and now the A/C will not blow out the front vents. Works on defrost and on the floor, and in the back. What's the deal?

the deal is that your a/c doors are now out of calibration. disconnect battery for 1 minute, hook battery back up. now turn key on, DO NOT START THE ENGINE, let it set for 2 minutes, now start engine, it should now work.

My 2004 trailblazer wont turn off when you turn the key to off posistion

hi, it sounds if it is a diesel engine,
the injection pump supplies metered diesel and cylider timing to the engine. at the back of the diesel pump is a little unit called a solinoid (igninion controlled valve) this valve may be stuck.
start engine and be very carefull and pull off the single connector, if engine do not stop your solinoid (ignition controlled valve) is not working.
old way of doing this in the past was pushing a rod to turn off the diesel. i hope this is usefull to you bye for now gerry

Ignition key 2004 envoy

I had same problem. I would sometimes also leave the door open with lights on inside for 5 mins - then I could not start car, and key would not release.

I had a bad cell in the battery. Replaced the battery and all worked fine.
