You must be able to turn the key to the run position. If that is still possible, then there is a pin on the side of the lock cylinder assembly than can be pushed in with a small punch, peperdicular to the cyclinder, while you pull the cylinder out. you must remove any shrouding parts around the steering column. Good luck! If the cylinder will no longer turn to the run psition, try tapping the key into the lock with a small hammer, LIGHTLY. That will sometimes allow you to get it into the run position, which is neccessary for cylinder removal. If not, contact a lock smith.

I have a 2004 Alero Oldsmobile if I buy the chipped ignition does it reprogram itself for the anti-theft device


Chipped ignition ? Key's on your car do not have transponder chip . Replacing Keys
The ignition lock cylinder and keys do not contain any coded electronic components. The lock cylinder housing contains the coded electronic components. Changing an ignition lock cylinder or replacing a key is a purely mechanical process which does not affect the vehicle theft deterrent system. To replace an existing key, simply cut a new key to match the existing one. If no keys are available, the lock cylinder must be changed. To change the lock cylinder, simply replace the existing lock cylinder with one of the same type.

How to start my 2004 2wd ford freestar without a key so I can change my ignition switch


You need the key in order for the vehicle to start. If you are referring to the ignition cylinder/key assembly that you are changing, you will need the key in order for the cylinder to turn and properly remove the cylinder

If I buy a ignition at autozone for my Pontiac Aztek 2002 would just start with the key in the ignition I put in


If you don't change the key cylinder, it should work.
If you change the key cylinder, you would need to cut a new key with a blank that will match the chip in the old key.

Is the door lock cylinder the same as the ingnition cylinder if I was to get a key made ??


Yes; It is a universal key that works for the door and ignition switch, as well. Make sure that your original key dose not have a chip in it. If so, you will need to order the equivalent from the appropriate dealership. You shouldn't have this problem, but be sure to check before having that spare key made...

Again; The door lock cylinder and ignition cylinder share the same key formation.(original key formation)

  • NOTE_ if you have changed your door lock cylinders for some reason and have not changed your ignition cylinder, this will present a problem, and the keys will not work universally. If all cylinders are stock, you should be able to have the key made and it will work on the ignition and door lock cylinders.

How to change lock cylinder on 91' Ford F250


You can grab the switch with pliers sometimes and break the tumblers of in the cylinder, if you can't get it to break, you can also drill it out. This is what we had to do on an 89 F-150 that the cylinder had worn out and broken on. You should be able to find some how-to's about drilling the cylinder online, maybe even some videos.

How do you change a key switch in a 2001 chevy impala, the factory keys wont turn in the switch


If your key is worn try getting a new one cut.
The ignition lock cylinder and keys do not contain any coded electronic components. The lock cylinder housing contains the coded electronic components. Changing an ignition lock cylinder or replacing a key is a purely mechanical process which does not affect the vehicle theft deterrent system. To replace an existing key, simply cut a new key to match the existing one. If no keys are available, the lock cylinder must be changed. To change the lock cylinder, simply replace the existing lock cylinder with one of the same type.
If you are unable to operate the ignition cylinder with a new key then you will probably need to replace the cylinder and switch.Replacement of the switch involves reprogramming
The system may be programmed with or without a scan tool.
There is a way to get the cylinder out without replacing the switch but this procedure should be performed by a qualified GM technician as it involves removal of the switch and some precise drilling.

What is the difference between a lock cylinder and an ignition cy


I think your question may have been cut off. Are you asking about the difference between a lock cylinder and starter switch?

I just changed both on a 1990 Lumina. As you turn the key a rod attached to the lock cylinder slides the starter switch between the different positions: Acc, Off, Run, Start. All the electronics are housed in the starter switch, while the lock cylinder manually places the starter switch in it's different positions. Does that make sense?

Typically new lock cylinders come with a new key.

I hope this helps! -Nick

How do I change an Ignition on a 1988 Ford Mustang GT Automatic Transmission


Not exactly sure when Ford changed the style. But I think it is this one. First of all do you have the key thet fits the lock cylinder you are changing? If so, put the key in and turn it to the run position. If this is the style I'm thinking about there will be a small hole in the column cover under the lock cylinder. A small allen wrench works fine. Push in with allen wrench and at the same time pull out on lock cylinder. (you may have to turn key alittle one way or the other to release pin.) If you don't have the key for this lock cylinder it will be EXTREMELY difficult to remove. Hope this is helpful .

REMOVAL & INSTALLATION

Functional Lock


The following procedure applies to vehicles that have functional lock cylinders. Such cylinders either have a key available or known key numbers from which a key can be made.
  1. Disconnect the negative battery cable.
  2. Turn the lock cylinder key to the RUN position.
  3. Using a 1/8 in. (3mm) diameter wire pin or a small drift, depress the lock cylinder retaining pin through the access hole in the upper steering column shroud (under the ignition lock cylinder) while pulling out on the lock cylinder. Remove the lock cylinder from the column.

Using the key, turn the ignition lock cylinder to the RUN position, then depress the retaining pin using a wire pin or small drift

To install:
  1. Install the lock cylinder by turning it to the RUN position and depressing the retaining pin. Insert the lock cylinder into its housing. Make sure the cylinder is fully seated and aligned in the interlocking washer before turning the key to the OFF position. This will permit the cylinder retaining pin to extend into the cylinder housing.
  2. Rotate the lock cylinder using the lock cylinder key, to ensure correct mechanical operation in all positions.
  3. Connect the negative battery cable.

Non-Functional Lock
The following procedure applies to vehicles in which the ignition lock is inoperative and the lock cylinder cannot be rotated due to a lost or broken key, unknown key number or a lock cylinder cap that has been damaged and/or broken to the extent that the lock cylinder cannot be rotated.
