We put the key in the ignition switch cylinder and it wont turn. what could be the problem and how hard would it be to replace the ignition switch and cylinder on a 1996 pontiac sunfire
Re: We put the key in the ignition switch cylinder and it...
It could be numerous problems, the battery, alternator or starter, If its making a clicking sound its probably not the battery. But if its not making a sound at all then its more then likely the battery

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.
try another key. the key could be worn where read coil in the ignition switch lock cylinder and immobilizer control module and ecm dont recognize ignition key or ignition switch key lock cylinder failing.
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.
Hello: You can try putting the key in the ignition and while trying to turn the key wiggle it and lightly tap on the key switch housing, If that don't work you can try a new key. If that doesn't work then you will have to replace the lock cylinder.
Remove the shroud cover, and the plastic ring around the lock cylinder.WD-40 the lock cylinder, Put the key in the ignition. Rap(Hard) on the back of the key while try to turn key. If it turns leave it in the ON(not run)and I'll tell you how to remove the cylinder.(If You need). The cylinder NEEDS to be replaced.
The Ignition Switch and the Key Cylinder are 2 entirely different things. If the key wont turn, find a Locksmith. The ignition switch is under the lower column cover and should be easy to replace.
take a small hammer and with the key removed tap the lock cylinder. then retry it the tumblers may be sticking. eventually you will need to replace the lock cylinder but this may help u get it going now
