Key stuck the ignition!

Is the vehicle in park ? Your vehicle like all vehicles have safety systems that won't allow the vehicle key to be turn off and locked if the vehicle is in gear and running . How ever this systems can malfunction . There is a lock out soleniod in the column or the console if floor shifter . The first place to start would be to have it checked for DTC's - diagnostic trouble codes . These codes can cut diagnostic time down a bunch . Or there could be a problem the ignition lock cylinder ! If no codes are present taking the steering wheel off to get out the lock cylinder and replacing it . You may be better of taking it to a repair shop .

Some ignition system locks will not release the key unless you push in towards the column while turning further off. It is a safety device to stop in advertent removal of the key while moving. Try that first.

on my car when that happens i pop out the button on the gear shifter.

Turn your steering wheel left or right side. If it moves, then good for you. But if doesn't, it probably means that locking system in the steering wheel is damaged. For this, you can just turn the steering wheel opposite to the direction of the car wheels. Most of the time, cars are turned off with the wheels turned on the opposite directions, which makes the key get stuck in the ignition due to pressure in the steering wheel. When the pressure is released from the steering column, a click can be heard and key is released.

If no luck, there might be a problem with shifter mechanism, which means that you have a trip to the repair shop in store for you. Get this problem addressed immediately, as it could mean that your shift interlock is out of order, which can increase the chances of deploying the air bag up in your face, causing a serious injury.

Rock Steering Wheel Back and Fourth While Turning KEY.

Or If the Wheels are Turned HARD in one direction you mest Turn Steer Wheel in THAT Direction While Turning KEY

If your key won't turn, you can move the steering wheel back and forth until it does or try to hold the steering wheel to the left or right while turning the key. This happened with my car when I parked with my wheels turned in. Now I make sure the steering wheel and my wheels are straight when I park.

I had the same problem and found that if I made sure the button on the shift lever is out all the way the key would come out. Mine was sticking and had to be pulled out, the spring had become weak on the shift knob.

Maybe you lock the stirring wheel. Insert the key try to turn it and at the same timeand try to stir (gently) clockwise or counteclockwise to unlock the wheel
Good Luck

Try a little wd 40.My T5 wouldn't let the key go when engaging PARK.A few squirts of wd 40 down the shift mechs solved the problem
