SOURCE: can't remove key from ignition. battery is dead

If the battery is dead, the ignition keys will not release from the ignition. If there is no signal from the transmission shifter that it's in park since the battery is dead, then the ignition lock will not release the keys.  After charging the battery or jumping the blazer to start it and the key's still will not release, try this. 
There is a "plunger" as part if the ignition. Under the steering wheel there is a small removable cap that you can take off and put a small screw driver up into and press the plunger in and it will release the key. Good luck and hope this helps, Keep me posted be glad to help.

SOURCE: 03 monte carlo wont start... turn key to AC

the noise your are hearing is the fuel pump, you might need a new battery by the sounds of it, or your ground is corroted or your connections arent tight and could be causing the power failure,check your battery system over and down to the starter, if its not grounded right it wont start it will just go blank.

SOURCE: 2006 chevy trailblazer will not start/turn over,

Sounds like the starter is the culprit,when the brushes in it are almost gone they will work intermittently and if the brushes aren't touching then you won't even get a click because of the lack of ground for the pull in portion of the starter solenoid winds.The next time it won't start,give the starter a tap or two to confirm this.It should start if i'm right.The starter is under the passengers side just to the rear of the front tire,bolted to the bell housing.

Does the vehicle start an run ?Can you turn the key to the off position ? And the key won't come out ? Did you try some key graphite ( lube ) ? New lock cylinder need maybe . Or is it a problem with
Steering Column Electric Park Lock
If the vehicle is equipped with a floor-mounted console gear shifter, an added safety feature is an steering column electric park lock system in the steering column. The steering column electric park lock system prevents the steering wheel from being locked when the transmission is in gear and the vehicle may be moving. The column ignition lock system consists of a steering column electric park lock and a park position switch, that is located in the A/T shift lock control switch. The steering column electric park lock contains a spring-loaded pin that mechanically prevents the ignition key cylinder from being turned to the Lock position when the transmission is not in the Park position. If vehicle power is lost 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.

No power electric problem


No, not a relay. The ignition switch is too central to the electrical system. It sends power out to most circuits on the vehicle-those that are designated "hot in accessory, run, start" or some that are only "hot in run or start". Being central, it requires a direct battery source, a "hot at all times" source. Anytime the battery is hooked up, the yellow wire to the ignition switch is a hot wire (actually 2 yellow wires-they splice off before entering the switch or before entering the electrical connector for the switch). The source is Fusible Link M on the starter relay, one of many Fusible Links there, and tied in with the positive battery cable connection. So also, the alternator link is there, so is the headlight switch, the hazard and brake lights Fusible Link, and some others that do supply relays (fuel pump, eec relay, etc.). But Fuse Link M is dedicated to only the ignition switch. If you have no power at the connection to the switch, look at fuse link M. It should have some identifying legend or mark.
Where you saw the sparks, was it at the switch itself or the electrical connector to it? Either way you will have to check. If at the switch, It could be a bad switch, and may have also blew out the fusible link. If at the connector, check if it damaged the connector and is losing contact. Post back with what you find. Good luck.

Removing ignition switch


The electrical part of the ignition and the key cylinder are both easy to replace. Disconnect the battery first so you don't trip the airbag my mistake. Remove the cowling below the steering column and you will see the ignition switch on the left side. There are a couple of screws that secure it and plug in connector. The cylinder lock must have the key in to remove it. There is a detent pin that must be pressed that is not visible when the cowling is in-place when the key is turned and it will slide out. The Haynes manual is very good with details and there is info on Youtube as well.

Ignition


he ignition switch generally has four positions: off, accessories, on, and start. Some cars have two off positions, off and lock; one turns off the car, and the other allows the key to be removed from the ignition. When the key is turned to the accessories position, certain accessories, such as the radio, are powered; however, accessories that use too much battery power, such as window motors, remain off in order to prevent the car's battery from being drained. The accessories position uses the least amount of battery power when the engine is not running, which is why drive-in movie theaters recommend that the car be left in theaccessories mode during the movie.

The on position turns on all of the car's systems, including systems such as the fuel pump, because this is the position the ignition switch remains in while the car's engine is running. The start position is spring loaded so that the ignition switch will not remain there when the key is released. When the key is inserted into the ignition switch lock cylinder and turned to the start position, the starter engages; when the key is released, it returns to the on position, cutting power to the starter. This is because the engine runs at speeds that the starter cannot match, meaning that the starter gear must be retracted once the engine is running on its own.

Either the ignition switch or the lock cylinder may fail in a car, but both circumstances have very different symptoms. When the ignition switch fails, generally the electrical wiring or the plastic housing develops problems. The car may not turn on and/or start when this happens. Also, the spring-loaded start position could malfunction, in which case the starter will not engage unless the key is manually turned back to the on position.

When the lock cylinder malfunctions, however, the operation of the key itself will become problematic. If the tumblers become stripped, the lock cylinder may be able to turn with any key, or you may be able to remove the key when the car is on. If the tumblers begin to shift, the lock cylinder may not turn. Sometimes the key can be wiggled until the lock cylinder turns, but it is important to remember that this is only a temporary fix.

Replacing an ignition switch can be tricky business, particularly in newer cars, because of the anti-theft devices used in cars. Once the ignition switch is separated from the back of the lock cylinder, the car can be started with a screwdriver, making it vital that this switch be difficult to get to. It is important to consult a shop manual before attempting this kind of repair, as the anti-theft devices may require special tools; attempting to remove an ignition switch without the proper tools can render the car inoperable.

My 1991 eb ford fairmont starts when i turn the key but stops as soon as i let the key go


Hello, It sounds like a bad Ignition switch. The keyswitch provides power to its terminals in back of the switch. The engine will have power to turn the starter and run the engine when the engine is in the START position. When the key returns to the RUN position, the next terminal on the switch is suppose to provide power to run the engine.

When the electrical contacts inside the switch wear out, the power is not put through the plug-in terminals. That is when you replace the Ignition switch.

To replace the Ignition switch, if it is in the steering column, you disconnect the negative battery cable first, and then remove the plastic cover on the steering column. There are screws under the bottom cover and you just remove them through the small holes moulded in the plastic cover. There may be a hole near the bottom of the Ignition switch which requires a long nail or drillbit to press a release spring.

Usually the key needs to be in the ACC or RUN position and the key core will pull out of the switch. Then you make a mark on the frame of the steering column before removing the switch. Some mounts are adjustable and some just bolt up and making a mark is not necessary.

Then reverse the removal procedure to reinstall a new part.

What is the procedure to changing an keyed ignition lock?


Hi there,

Removal

Disconnect the negative battery cable with the proper size wrench and place away from the battery.
Insert the key into the ignition lock cylinder and turn the key to the run position.
Remove the steering column cover on a tilt steering wheel model by pressing the upper and lower section of the cover together and pulling free from the mounting plate. Remove the steering column covers on a non tilt steering wheel model by using a Philips screwdriver and unscrewing the mounting screws.
Disconnect the electrical connector from the ignition switch by lifting up on the release tab and pulling.
Press the ignition switch actuator pin by pushing a small screw driver into the key lock cylinder, while doing this pull the ignition switch out of the ignition switch housing.

Installation

Insert the new key into the new ignition switch and turn the key to the run position. Insert the new ignition switch into the ignition switch housing. Wiggle the switch back and forth until the actuator pin mounting hole is aligned and falls into place.
Install the electrical connector back into the connector housing by pressing it in with your hands.
Place the steering column covers back onto the non tilt steering wheel and insert mounting screws. Tighten screws using a Philips screwdriver. Place the steering column covers over the tilt steering wheel and press the upper and lower portion together to snap covers back into the mounting plate.
Pull on the ignition key to ensure switch is locked into place. Turn key to the "off" position and remove the key. Insert the key and start the vehicle.

Hope these help.
