Cant start my car, key wont turn in the ignition.

sounds like the ignition key switch is worn and needs replacing.

This usually happens if your steering wheel is in the rightmost or the leftmost position. Try wiggling the steering wheel when pulling out the key.

cant turn off problem you can try another key.put key in the ignition turn on position for 3 seconds the security light should turn off.then turn off ignition switch wait 5 to 10 seconds try start vechicle if still fails to start.problem in the theft security system.dealership has to code scan problem could be in the ignition switch which is antenna ring.problem could be transponder key or problem could be in the immobilizer control module and ECM.

Try checking the key reader it's usually a plastic ring around the key barrel. If it's dies will not read code in key to enable the car to start. Check your key is sending a code as well.

Push in turn back all the way. You may have a lever u have to push or its not in gear all the way as in park.

sounds like the ignition lock cylinder has gone bad call a locksmith.

i think there is a ignition problem , might try replacing it , of course you cant turn the steering if the key wont turn , its a theft prevention device.

if you turned the key with the ignition with the imobilizer, you now have to get the right ignition and a new PCM because the PCM now thinks the car has SKIM (imobilizer)

The solution lies in the interlock with the shift linkage. Make sure the transmission and therefore the shift colomn make it into park or neutral.

Make sure car is in park then try moving ignition switch back towards you and then forward as if trying to start it. That seemed to work for our 86 Dodge 600 auto.
