Why would my ignistion key be stuck?

SOURCE: key locked in ignition... can't get it out. HELP!

I had this problem. To get your key out a pencil or thin bolt 2-3" long is needed. Look under the steering wheel and you will see a hole (not a screw hole). Press up with the pencil and you will depress a lever and you can turn and remove your key. You can keep doing this forever, if you like, but the problem is the neutral Park switch which is located under the console where the shifter is. When you get the cover off, which takes a little patience, you will see a switch up towards the top near the Park position. There is a broken or shorted wire that connects to that switch. I think in mine and maybe yours the wire was installed in a bad spot and got pinched, eventually it breaks or wears thru. How it works is when you put it in park it touches thaat switch which turn on a tiny sloenoid in your key mechanism which depress that lever you pushed with you pencil, and you can then turn off the car and remove your key! Fix the broken wire and you are back in business.

On many cars, if the battery is dead, it locks the key in the ignition. Put a battery charger on the car or replace the battery and give it a shot.

Good luck.

It is the security chips in the keys. Has this car been wrecked? Was this car made in Mexico? GM had the bright Idea of creating a security system that would do exactly this, I know on cars made in Mexico (like the HHR) You can reset the power and get the key back out, but vehicle will have to be reprogrammed with the master key. This involves turning the key from off to run position without ever going past run (i.e. start position) leave key in this position for 30 minutes. Turn key back to off for 30 seconds then back to run for 30 minutes. repeat this step three times. the last time, after 3rd 30 minute period, turn key off for 30 seconds and then try to crank. Please note this only works if the original master key is being used. You can then reprogram the second key following a similar sequence, only master key that is working has to be inserted to let alarm system know that vehicle is not being stolen only that you are trying to reprogram a key. If original master key is not being used then vehicle has to be taken to the GM dealership to program keys and possible key module replacement.

A simple way to make your car secure without removing the key is ti run a wire from the positive side of the coil to a good quality toggle switch that you can mount in a discreet location (possibly somewhere easily accessable) then run a wire from the other side of the toggle switch to a metal surface ,and attache the wire with a small sheet metal screw, when you flip the switch to the on position it will ground out the coil thus preventing the engine from starting. Another way is to buy a battery cable with a switch already installed, but that is a real pain to turn on and off as you must open the hood of your vehicle to activate the switch
In my opinion the toggle switch is easy and cheap to do . It creates a theft proof system for very little money or work
