Ignition key won turn

if you mean the key won`t turn to start the car you may have a worn key and or ignition switch. try another key to see if its the key. also make sure there is not tension on the ignition by way of the steering wheel being turned in the full left or right turn causing tension on the ignition.

probably need a new ignition lock or your key is wore. ignition locks arn't too bad to change depending on the vehicle.

ignition keylock cylinder broken or could have the wrong ignition key.

Make sure your steering wheel isn't locked. Sometimes a key won't turn until you jiggle the wheel while trying to turn the key.

If your steering wheel is locked, turn it a bit away from the locked position. Key should turn now.

Otherwise, you may need to replace the ignition or you have a bad copy of a key.

I have had this happen on my 98 Voyager. Just have a new key cut. This new key will sometimes cure the problem. The older keys get worn out and won't unlock the ignition. Try this before a much more expensive and time consuming change of the ignition.

You need to carry out the periodical car service due (e.g. engine oil & filter, air filter, fuel filter, cabin air filter). The "service" spanner symbol "reset" button is placed on the lower right corner of the dashboard. See picture below:


Then you should reset the "service" spanner symbol by pressing on the "reset" button on dashboard, when ignition key is in OFF position. Hold the button pressed and turn ignition key in ON position. Hold the button pressed and see on the dashboard successive numbers will appear: "10", "9", "8", ... , "1", "0". Then release the button and switch OFF the ignition key. The "service" spanner symbol followed by "20000 km" (or "30000 km" depending of the engine type), will appear for few seconds after turning ignition key in ON position, and will dissapear after engine starting. The car service due was reseted.

Please do rate my response. Thanks!

the key may be worn badly or the ignition needs to be replaced.
