Either something is wrong with the key or there is something wrong with the switch. You can try to spray some WD-40 or something like it into the switch and wiggle the key to see if you can get it turning. Otherwise you may have to replace the ignition switch.
The manual says to turn on the ignition.
Turn the ignition key on for 10 minutes and it will reset.
Were Under dssh is it
If your ignition will not turn, try turning the steering wheel slightly while you turn the key. Sometimes the steering wheel will get locked in place and doing this will allow the ignition to move again.
Probably the ignition key switch...I have the same problem
Maybe your steering wheel it's keeping the ignition cylinder to turn, so move the steering wheel and at the same time try to turn the key. Maybe you need to replace the ignition cylinder key lock
Remove steering wheel, turn signal (4 screws), and torx holding ignition, reverse to reinstall.
I'd call a locksmith. They will be able to tell you the exact problem and how to fix it.
When you turn the ignition on the CHECK ENGINE light will not light up at all.
sounds like u need to change the ignition switch itself ( the keybarrel)
I've had this problem where I couldn't start my car and it turns out it was because the security light was on. To fix it: Place the key in the ignition and turn it one rotation (so battery is on) then leave it in the ignition for 10 minutes. Restart car and security light will be off.... also car will start!
