Why Is There A Flashing Red Car With Key Icon Nissan?

What is the feasible culprit behind the seriousness of this flashing red car security indicator light? The answer ranges from electrical interference, faulty key, dead key fob battery, faulty control module, and faulty key antennae.

Electrical interference: As for electrical interference’s explanation, Nissan keys operate on radio frequencies (RF), much like other wireless daily used gadgets.

It is therefore understandable that the signals being received by the BCM may be hampered if whichever wireless device is broadcasting at the same time as your key.

Faulty key and dead key fob battery: Similar to when the key fob doesn’t unlock your car, we can all agree that there won’t be much to say about these two occurrences.

Either finding your right key or replacing the battery is sufficient to get rid of the trouble.

Faulty control module: Things turn a lot more complicated when it comes to the faulty control module. In this case, not just your warning light but probably other automobile parts are affected by that.

The faulty key antennae: This one is another potential suspect that can make up the scene.

As you can see in the accompanying diagram (of the owner’s manual or handbook), it is affixed to the floor console’s underside.

Yet, it is still advisable to take yours to mechanics to diagnose and cure the symptom.

Can You Drive With The Red Key Warning Light On? (Can You Drive In Fail-Safe Mode?)

No, when the flashing red car light is on, the car will usually not be able to start.

If you’ve pumped into the dead end and have no other way rather than to get the car fired up, a fail-safe mode is a workable approach you can put into use.

As such, the ECU will restrict the vehicle’s ability to drive normally once this limp or failsafe mode is engaged.

In rare cases, the ECU will allow you to limp home or to a mechanic while limiting the car’s performance or speed to prevent further harm.

How To Fix Flashing Red Car With Key Icon Nissan?

As for other scenes in which electrical interference, the faulty control module, faulty key antennas occur, or the issue simply doesn’t go away, you’ll need to tow the car to a shop that can fix the security system.
