Key won’t turn like the wheel is locked but it’s not, the key signal don’t come on on the dashboard and the sound when leaving the driver door open with the key in the ignition don’t work either, and I discovered that using the tip of my key turns it but nothing works but sometimes I can get it to the point all the lights come on on the dash and everything works but can’t turn the engine on. How do I fix it please?

Hi,

It sounds like the key lock cylinder has failed. If you are able to turn it partially by only placing the tip of the key in it, the tumbler must be bad. That could also be causing the issue with it not turning the entire way to the start position.

Now, to test the key lock unit requires removal of the part. In addition, the steering column needs partially removed. To add insult to injury, if you replace it, the vehicle's computer will need programmed to recognize the new key and lock assembly. It's not an easy one to do.

_______________________________

Here are the directions that explain how to remove and inspect the ignition lock assembly. Based on your description, I suspect this is the problem, but testing will confirm. The attached pictures will correlate with the directions.
