A 2009 Nissan Altima experienced a no-start condition after a brief stop. The steering wheel was locked, and a clicking sound could be heard from the steering lock mechanism. After towing the vehicle to a mechanic, the steering lock was removed and disassembled, and the internal motor repositioned to unlock the steering wheel. However, the car still wouldn’t start, and the “NO KEY” indicator illuminated on the dashboard.
A diagnostic scan revealed an error code related to the steering chain in the body module. After clearing the code, the car started. Unfortunately, after driving and parking, the vehicle reverted to the “NO KEY” state and wouldn’t start again. This raises the question of whether disabling the steering lock entirely, potentially by cutting a pink wire often mentioned in online forums, is necessary to permanently resolve the issue. While many have reported success after disabling the steering lock, this case highlights a potential complication involving the steering chain code and its interaction with the vehicle’s immobilizer system.
