There's a frustrating issue with some Nissan vehicles where the ignition key fails to be recognized, often leaving drivers stuck. This 'key recognition problem' can happen due to a dead key fob battery, a worn key, or a sensor fault in the car. When it occurs, you might not be able to start the engine, and the security system may prevent the car from unlocking. It's a known glitch that sometimes requires a replacement fob or a reprogrammed key to fix.
