Why I can not turn key

There are rumors that there are "hidden" features accessible by the dealer. If this is something you dont want, contact your local dealer and ask if that is something they can turn off.

year make model, manual or automatic?

Automatic? Foot on the brake, rack the shifter through all the gears and back to Park and it should release.

maybe fob is damaged, and wont open with key as it may be worn , do you have a spare key to try.

Try turning the steering wheel back and forth while turning the key. If this doesnt do it pull the shift lever up all the way into park ( if automatic ) and then try to turn the key. Last resort if two edged key try turning the key over.

Turn the key on, Leave the key on for 10 minutes until the theft light goes out. Turn the key off. Then it should start the next time you turn the key.

Are you all the way in Park, if it's an automatic, and have you tried turning the steering wheel while you turn the key? There could be pressure against the lock on the tumbler.

here are the timming marks



the other important thing is to
Rotate the automatic tensioner hex–key tab anti-clockwise until the adjust arm pointer of the timing belt automatic tensioner is aligned with the notch in the timing belt automatic tensioner bracket.
then turn engine over 2 turns and recheck marks and tensioner pointer

have you tryed to turn the steering a little bit, at the same time turn the key.

The immobilizer does not "lock" the ignition, it does not energize the fuel injection relay. What you have is a "locked" steering column. Put the key in the ignition, and pull/turn the steering wheel HARD left or right, whilst turning the key to on or start. Do BOTH at the same time.The action of you pulling on the steering wheel will unlock the steering column.
