When you replaced the cylinder was it new or second hand did you put some lock grease in before assembling the cylinder and barrel.?

SOURCE: I have a 2000 GMC

You can drill it out. I have had to do this on 2 occassions. First...pull the cowel off around the steering wheel. Get a good light and look closely...some of the screws in the plastic can really hide on you. With cowel removed....look for and opening (small hole) where a little pin sits. Grab a very small screwdriver or pick and push down on that pin while you wiggle the key and try to turn it to the "on" are supposed to put it in the "on" position in order to push the pin in and pull out the cylinder, but you may have some luck seeing as though the tumblers are broke inside. If this doesn't may be drilling it out. Check with dealer too. If you have a plastic top on you key...and a security light and your car....a NAPA or Auto Zone part is not gonna work. You need to buy a key lock and cylinder assembly from the dealer and follow the key up procedure to reprogram the new key to the BCM. when you get a little further into getting it out...I can walk you through getting it in

Before you replace the cylinder, you might want to try cleaning the cylinder first, its fairly easy and quick.
Use some WD-40 or equivalent and place the spray tube into the tumbler opening were the key would normally go. Make sure you have a rag or something to catch the excess that runs out. Try to flush it out as much as possible.
Then using a can of compressed air, blow the cylinder out, you may need to repeat as necessary. The process should clean debris that is sticking the tumbler.
Give it a try, it should save you some time and money.
Let me know.

SOURCE: 95 suburban, ignition locks, can't turn key,

Remove the lower steering column cover and check to see if the rod from the ign. lock and tumbler to the ignition switch is binding up. If it's ok, you're problem may be the bearing under the steering wheel being broken.

Key wont turn pass acc it locks how can i fix

Ignition key cylinder tumblers are worn out!
Time to replace the cylinder.
Help prevent this from happening again by lightening your key ring load. A heavy key ring puts constant pressure on the lock tumblers and wears them down to eventually deform and prevent the tumbler cylinder from turning.
Most people employ the philosophy, "if it jams, just force it", which bends the weakened lock tumblers and hastens destructive wear.

Does the emobilizer and key have to be replaced if the wrong key was put in ignition and had to be pulled and wiggled pretty hard to remove now it wont start

When you turn the ignition switch to ON(II), the immobilizer system indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key. Turn the ignition switch to LOCK(0), remove the key, reinsert it, and turn the switch to ON(II) again.If the system repeatedly does not recognize the coding of your key will need a repair.

Key wont turn on 2004 Alero. If key is inserted and door is opened the alert bell sounds off indicating keys have been left in ignition,but that is all that is functioning. Have tried 2 different keys and...

Ignition lock cylinders are pretty notorious for this. You may get the thing to turn by wiggling the key up and down while turning at the same time. I have also had luck in tapping on the cylinder with a screwdriver handle while turning the key. To completely fix the problem, you will have to replace the lock cylinder. GM (AC Delco) lock cylinder kits come with an assortment of tumblers so the new cylinder can be set-up to work with your existing keys.
