If the key won't turn all the way's probably a bad lock cylinder.

Holden cruze 2009 key stuck in the ignition won't go to off position , can't get it out of park .What is the problem ?

Is it shifter on the floor ?
Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control actuator , and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

GM had problems with these ! Has a TSB - technical service bulletin !
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

Why can't ignition key be removed?

Sounds like the solenoid mounted on the shifter. You have to replace the shifter to replace the solenoid. I would check the resistance of the solenoid. Usually 30 to 40 ohms. check the plug to it(Corrrosion) and the resistance of the wires from the brake switch to the solenoid(5 ohms or less). Those shifters are cheap. Could be the brake switch also. Next time it doesn't work, See if the brake lights come on.

What causes my gear shift to lock in park

Manufacturers have designed the shifters to lock in the Park position. This is to prevent children from accidentally moving the shifter out of Park if they are playing behind the wheel (as they should not be of course). The ignition must be in the ON position, with the brake pedal pressed, to release the shifter from PARK. If there is a malfunction, most cars have a bypass release button hidden near the shifter. Check your owners manual for details if needed.

Key trapped in ignition

Could be the ignition lock or switch, but it could be the shifter too.
If the shifter is not completely in park, the key will not go to the lock position.

Audi transmission shift

Park is release by a small solenoid, the solenoid is powered up by the brake light circuit, so if the brake lights don't work due to a bad switch or wiring issue at the switch park will no release. If the brake lights do work then the wiring to the solenoid may be defective or the solenoid is sticking. Every car I have ever worked on has a bypass for the park lock, check your owner's manual for information on bypassing the lock out when this type of problem occurs.

When i start my 2002 grandprix gtp shifter is locked have to turn off ignition use ignition key in consol put in nutural then start it then i can put it in drive and go would this be a fuse by any chance.

if you pull around the area were the key goes in by the stick and you can get the plastic out of your way you will notice the key just pushes the nuetral safety switch in thus allowing you to put it in nuetral. your pushing the brake should do the same thing if not cut the wires on the switch one by one it will be permantly disengaged. but just drive it as normal youll never know the difference.

Car won't shift right away I have to pump the brake forever first

Ya it's possible, there is a shift interlock solenoid on the shifter that will only release the shifter when it has power from the brake light switch. There is also a solenoid on the ignition switch that won't allow the key to be turned to lock unless the shifter is in park. That is whats clicking.

Key stuck

Hello. Your problem is in the area called Brake Transmission Shift Interlock (BTSI). The shifter assembly in the console has a switch-solenoid (shift interlock) that has to send a release signal to the key release solenoid in the steering column. Replacement of the shifter assembly or shift interlock solenoid normally resolves the problem. regards, Joe
