Is your steering wheel stuck in the lock position?
For models equipped with the Intelligent key system and NVIS/IVIS, an electrically controlled steering lock mechanism is adopted on the key cylinder. For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible.
There is a specific procedure to follow to avoid this before doing repair work, but it sounds like that was missed.
To get the key to turn to the ACC position you'll need to unlock the steering wheel. To unlock your steering wheel, use your left hand to wiggle the steering wheel left and right with significant force. At the same time, use your right hand to turn the ignition key from the LOCK position to the ACC (accessory) or START position.
These are generic alarm immobilizer reset procedures and they apply to most vehicles.
Drivers Door Key Reset
Exit the car with all doors closed and the windows rolled up. Also close and any rear doors such as the trunk, rear hatch and front hood. Lock the car using the drivers side lock and walk away from the car at least ten feet. Wait for fifteen minutes and unlock the door, this should reset the security system.
Activate the Key Fob
Many manufactures will not allow the car to start when the panic button has been pushed. Hold down the panic button for five seconds to reset the immobilizer. Next, push the lock button two times and wait ten feet away from the car for ten minutes. Then hit the unlock button on the fob twice this should deactivate the security system which should be accompanied by exterior lights flashing or an audible horn beep.
Each of these procedures should be followed by the cancellation of the security light. If this light is blinking while you are trying to crank and start the engine the system is not reset.
