Ignition key will not turn, 2007 Nissan Murano

This guy

Pawel Nietyksza has no clue ,don't wast your time looking for a programming button, there isn't any. You need a factory or some other type of professional grade scan tool to program the key for anti-theft system immobilizer.

If the engine sounds as if it wants to start, it is possible that you just have too much gas in the manifolds or in the cylinders. Try the following: Turn on the ignition but do not start. Hold down the gas pedal for a minute or two. Then start the car without releasing the pedal. I know some will say this method will not work with "drive by wire" systems such as MO's but I think it will.

More than likely though, the problem could be the anti theft system interfering, or locking down the ignition. Close all doors and then using your key (not the fob) lock and unlock the doors several times and then try.

The chip was damaged. U need a new programmed key. Obviously you don't have a spare key.

Is the front tires turned and up agains the curb if so pull on steering wheel and try turning the key when you shut off the car the presure goes to 0 in the steering system and it can put a bind on the steering wheel

Unfortunately, the keys have an anti-theft chip in their bodies that communicates with the car's system.
Try Googling ("Nissan/car key programming" for a cheaper price or phone independent garages. The keys can probably only be done by an authorized Nissan dealer. Also, phone locksmiths for their opinion.

Sometimes the steering wheel gets torque locked. Try turning the steering wheel one way then another while trying to turn the ignition.

These new security systems are a pain, aren' they? You may have to take your vehicle to the dealership to find out what the problem is. It Will most likely get worse over time, until one day the key just won't work at all.

nissan recommend to keep the fob away from other electronic device anything else on your key ring that might have affected it
