What Does The Car With Key Symbol On Dashboard Nissan Mean?

The car with key inside symbol Nissan in the instrument panel is the security indicator light. It is connected to the NISSAN Anti-Theft System (NATS), also known as the immobilizer system.

The immobilizer does not allow the engine to start without the registered key. The key carries a chip that the car reads before the engine is allowed to run.

Simply put, the red car symbol on dashboard Nissan will let you know that the anti-theft system is in operation or if there is a problem.

This indicator light is usually red. Do not confuse it with the Intelligent Key messages, such as Key Battery Low or No Key Detected, which appear on the information display.

You can read more about these messages in our post on the Nissan Intelligent Key warning light.

It applies to most Nissan models with the immobilizer, such as the Rogue, Altima, Sentra, and Kicks.

Is It Normal For The Red Car Light On Dashboard Nissan To Blink?

Yes. The red car light on dashboard Nissan should blink whenever the car is off. On vehicles without the Intelligent Key, the light blinks when the ignition switch is in the LOCK, OFF, or ACC position. On vehicles with the Intelligent Key, it blinks when the ignition is in the LOCK position with the key removed.

In other words, a blinking key warning light means the immobilizer is operational. It also tells outsiders that the car has an anti-theft system.

You shouldn’t be concerned if the security light blinks on the dashboard while the vehicle engine is off, and you can easily start the vehicle.

On the other hand, if the car key symbol on dashboard Nissan stays on while the ignition is in the ON position, or the engine won’t start, this is a sign of something wrong with the automobile.

Why Does The Key Sign Light Keep Turning On Dashboard Nissan?

Suppose the car with key symbol on dashboard Nissan stays on and the car won’t start; this can signify the following problems.

Malfunction Immobilizer System

If the red car light on dashboard Nissan remains on even when the ignition switch is turned to the ON position, the Nissan Immobilizer System isn’t working properly. Nissan manuals say the light stays on in the ON position when the system has a malfunction.

In other words, your automobile might not be able to identify its key.

Interference On The Key Ring

Nissan says the engine may fail to start with a registered key when another NATS key, an automated toll road device, or an automated payment device is on the same key ring.

Thus, Nissan recommends placing the registered key on a separate key ring.

Problem With Anti-Theft System

When you try to start your automobile and the car with key symbol on dashboard Nissan Rogue stays on, but the engine won’t start, you may have an anti-theft issue.

The system might not recognize your key. Keep in mind that the car only accepts a registered key. A copied key that was cut but not programmed will not start the engine.

In this case, we suggest you bring your car to a Nissan dealer so that you can solve the problem as soon as possible.

If you see a key ID message on the display, you can read more in our post on the Nissan Altima key ID incorrect.

Faulty Key Or Fob

If your key has nicks, scratches, or any damage, your vehicle may not recognize it. Similarly, a cracked key fob or one with a low battery can prevent the car from recognizing it.

On push-button start models, Nissan manuals say that messages such as Hold Key Near Start Button appear when the Intelligent Key battery is running out of power or when the key and vehicle are not communicating normally. If you see Key Battery Low on the display, replace the battery as soon as possible.

You can also read our posts on the Nissan key battery low message and the Nissan Altima no key detected message.

Dying Battery

A weak or dead car battery can cause strange electrical behavior, including no-start problems and warning lights. Thus, if the car cranks slowly or the dash lights are dim, test the battery first.

Plus, if the battery light also comes on, you can read our post on the battery and brake light on Nissan Altima.

How To Fix The Car With Key Symbol Nissan On Dashboard?

If the car with the key symbol on your Nissan dashboard stays on, it indicates an issue with the anti-theft system. Here are steps to troubleshoot and fix the problem:

Use A Spare Key

Try your spare key first. If the car starts, the first key is the problem, usually a weak battery or a damaged chip.

Check your key for damage along the teeth or near the base. When you see nicks, dents, or damage, it’s best to replace your car keys at a local dealership.

Clear The Key Ring

Remove toll tags, payment fobs, and other NATS keys from the ring. Hold them away from the key you use to start the car.

Restart The Ignition

Leave the ignition in the ON position for about 5 seconds. Turn it to OFF or LOCK and wait about 10 seconds. Repeat this once, then start the engine while holding any possible interfering device away from the key.

Some models vary slightly, so check your owner’s manual.

Replace The Key Fob Battery

If you have a keyless ignition, change the key fob battery. Most Nissan key fobs take a CR2032 battery, but some models use a different type, so check the old battery or the manual.

Still, take caution when opening the fob to avoid damaging the circuit board, and pay attention to which side of the new battery faces up.

Use The Backup Start Method

On push-button start models, shift to Park and press the brake firmly. Touch the Intelligent Key to the start button until you hear a chime. Then push the start button while pressing the brake, within 10 seconds of the chime.

The exact steps are in your owner’s manual.

Check The Car Battery

In case your car won’t turn on or start, the battery might be completely dead. Use a multimeter to check the battery’s power level, or have it tested at a repair shop.

Contact A Mechanic

If the light stays on while the ignition is in the ON position and/or the engine won’t start, Nissan manuals say to have the system serviced as soon as possible.

There is no effective DIY fix for an immobilizer fault, so you can contact a mechanic or a Nissan dealer. Explain that your vehicle’s anti-theft system is activated, and let them know what you’ve already tried.

The purpose is to check carefully for problems with the immobilizer and to register the keys with diagnostic equipment.

What About Other Fixes You Read Online?

Some guides suggest leaving the key in the ON position for 10 minutes, locking and unlocking the car with the panic button, disconnecting the battery, or replacing the anti-theft fuse or the ignition cylinder.

These steps are not in the Nissan owner’s manuals. Keep in mind that disconnecting the battery will also reset your vehicle’s clock and radio stations, and it can cause its own start problems on some cars. Thus, it is not a good first step.

Frequently Asked Questions

Can I Still Drive With The Nissan Key Symbol On Dash Constantly On?

If the light only blinks while the car is off, this is normal, and you can drive as normal.

On the other hand, if the light stays on while the ignition is ON, the immobilizer may have a malfunction. The car may still run, but it may not start the next time. It is advisable to have it checked as soon as you can.

How Can I Turn Off The Anti-Theft System?

You do not need to turn it off. When the registered key is recognized, the system allows the engine to start.

You should start by attempting a different key if the security dashboard light is still on and you cannot start the automobile. The red car with key symbol Nissan typically indicates that the automobile does not accept the key you’re using, so you might be able to solve the issue by using a different one.

Call a dependable mechanic to help you diagnose the problem and reprogram the key if a second key does not work and the security indicator light is still on.

Can Anti-Theft Prevent The Automobile From Starting?

The quick answer is yes. This system’s objective is to protect your car from thefts, so according to Nissan manuals, the immobilizer will not allow the engine to start without the registered key.

This is why a car may crank but not fire when the key is not recognized, or not start at all.

Does The Nissan Security Light Drain The Battery?

The blinking light uses a very small amount of power, so it is not a concern on a healthy battery. Thus, if your battery dies after a few days, the cause is more likely something else, such as an old battery or a parasitic draw.
