The engine immobilizer is activated if you see a car with a key symbol on the dashboard. This security feature prevents the vehicle from being driven without the key.

There are several reasons why a car with a key symbol might flash on your Nissan's dashboard. Here are some of them:

Problem with the Immobilizer System

A malfunctioning immobilizer system is a common cause of the car with a key symbol flashing. If your Nissan's immobilizer system is faulty, the vehicle might not recognize the key, triggering the security system and the dashboard symbol.

Low Battery of Key Fob

A low-key fob battery is another reason the car with a key symbol might appear. Key fobs need regular charging to function properly. If you last charged your key fob a while ago, its battery may be depleted, causing the symbol to flash.

Damaged or Drained Battery

It's critical to maintain the battery in your key fob. If you're still using the original battery, it might be time for a replacement.

Faulty Anti-Theft System

If the car with a key symbol lights up as you start the vehicle, preventing the engine from starting, it could indicate a problem with the anti-theft system. This might happen if the system fails to recognize the key.

Low Battery of the Car

Like a low-key fob battery causing the symbol to flash because the system can't detect the key, a low-car battery can have the same effect. Leaving car accessories on can drain the battery, preventing key detection and triggering the dashboard symbol.

Problem with the Key Lock

A faulty key lock can also cause the car to have a key symbol warning light on your dashboard. Even with the correct key, a damaged lock won't open, and the system won't recognize it, causing the symbol to light up.

Theft Attempt on Your Vehicle

While it's an unpleasant thought, a theft attempt can also trigger the car with a key symbol. You'll notice the symbol flashing when you enter your vehicle after an attempted theft. Fortunately, this means the immobilizer system is activated, making it difficult to start the engine and deter theft.
