Im locked out of my car

lock cylinders in either door do not work with key?

Well now you are using the wrong key again .. Try to open the trunk with it! .. That key probably fits the other 'Nissan' vehicle .. Put an ID tag/mark on the key that fits the Infinity .. There is no secret code for 'turning' a key .. It is either left or right!

Now,do you really think someone here is going to e-mail you or even call you and that car could very well be stolen?
