Put the key into the door lock as the first step. Use the side door on the driver’s side and put the physical key into the lock even if you have a keyless car and don’t frequently use it.
Tip: The majority of key fobs—if not all of them—contain a real key. Look for a button that releases the actual key from the fob so you can slide it out.
Step 2: Rotate the car key to open the door without opening it. Keep the key in this position for 30 seconds. By doing so, you will let your car’s security system know that you have the right key and can disable the alarm.
Some vehicles can be accessed by merely twisting the key in the door’s cylinder back and forth. To disable the anti-theft system, it is advisable to attempt both holding the key in the door and twisting the key in both directions.
Step 3: Attempt to start the car. Remove your car’s key from the door and attempt starting the engine. Make sure the door cylinder is still in the unlocked position as you do this, though.

Your car’s anti-theft system is shown by the security light on the dashboard. It accomplishes two major goals:
When the engine is off: To signal that the security system is engaged, the security light may blink in some vehicles when the ignition is off.

Why is a red automobile flashing on Nissan’s dashboard?
When your Nissan’s warning light is red, you should take it in for service right away. An engine overheating or a brake system failure are two examples of significant system failures that are indicated by a red warning light.
What does Nissan’s red automobile with the key symbol represent?
The security indicator light is the Nissan car with the key inside in the instrument panel. The key warning light verifies that the security systems of the car are working.
The alarm and immobilizer system are probably in action when the key is not in the ignition lock or accessory position and the key light flashes.
Simply said, the red car sign on the Nissan dashboard will let you know if there is an issue or the anti-theft system is active.
When the engine ignition is turned to the OFF, AUTO ACC, or LOCK positions, this malfunction indicator light ought to flash.
If the security light on the dashboard illuminates when the engine is off, you shouldn’t be afraid because you can quickly start the car.
On the other hand, if the Nissan car key symbol on the dashboard is continuously flashing, there is a problem with the vehicle.
What does it signify if there is a red automobile with the Nissan key icon?
a key emblem and a flashing red automobile Nissan Altima typically indicates that a security fault code is present.
The car’s control modules must then turn on this alert light after the ignition is started with a key that is not preprogrammed for it.
The case also occurs when there is a problem with your vehicle’s security system protocol.
This flashing key indicator is frequently helpful in the Nissan Anti-Theft System and the Nissan Vehicle Immobilizer System to alert the driver to various protected relevances.
The list includes any doors that have been unlocked, unlocked but with the key removed, or both.
Since the Nissan Serena’s blinking red security light just serves as a standard communication element, you won’t often need to worry much.
Additionally, because this key light uses very little electricity, the battery won’t be discharged.
However, if the issue continues and none of the straightforward fixes you tried work, then perhaps there are some hidden potential harm.
The good news is that when you mess around with such a hassle by yourself, perhaps not much will go wrong.
However, any more severe red-light-related issues must be fixed in better maintenance at a Nissan dealer or approved repair center.
Why won’t the security light on my car turn on?
Hello. The security system has failed and is disabled if the security light on your specific car continues to illuminate while the vehicle is in motion. Due to the possibility that the computer may lose its programming for the key, it is typical for a security light to turn on after the battery dies. Reprogramming the ignition key should fix the problem. To make the security light turn on, I advise having the ignition and key reprogrammed by a specialist. It’s possible that if you turn off the security light while it’s on, the car won’t start again. Before making another journey, I advise you to get the car fixed. Alternately, you might try turning the car on and off a few times to check if it will start up constantly to allay your concerns that it won’t restart as you go about your duties, and then have the security light fixed as soon as possible.
What should you do if your security light doesn’t turn off?
The majority of motion sensor lights include a “override mode” built-in. In this mode, the light remains on constantly regardless of movement.
But most homeowners are unaware that turning the light on and off in quick succession for three seconds puts your security light into automatic mode.
What to do: Turn off the electricity at the breaker, wait a full 30 seconds, and then turn it back on. The security light should then briefly turn on, turn off, and return to its default settings.
My car won’t start while the security light is on.
Either the key itself or your anti-theft mechanism (pass-lock) may be at issue. The keys contain a chip inside of them. The alarm system checks the key for codes while it is in the ignition. If you have another key, use it. If it does, the first key has to be replaced since it is damaged. Take the key to the dealer to see if it actually transmits properly if it doesn’t start with the second key or if you don’t have one. Try this process if you have 2 keys and the car won’t start.
There are two fundamental relearn methods for the Passlock system: a ten-minute procedure and a thirty-minute procedure. The system and the components that have been replaced will determine which one you use.
Ten minutes later, the engine is still not running. The security light will be flashing in the absence of any events or if the engine starts and then stops. Wait 10 minutes with the key still in the On position. The flashing light should stop flashing or turn on steadily. When it happens, switch off the ignition, wait 20 seconds, and then attempt to start the car. Everything is fine if it starts and runs. Wait ten more minutes if you experience the same problem as before—nothing happens, or the engine starts and stops while the security light flashes.
The thirty-minute relearn procedure, which is really the ten-minute procedure repeated three times, will now begin. The engine should start and operate after turning off the ignition three times and waiting for 20 seconds. If not, there can still be a problem with the system.
The security light may remain steady for a few minutes after the learn procedure is finished and the engine is running before turning off. This is typical. Depending on the system, a retrain procedure may be required in order to replace important components. The key lock cylinder, Powertrain Control Module (PCM), Body Control Module (BCM), or Instrument Panel Cluster are a few of them (IPC). Your only option may be the dealership service center if the relearn method is unsuccessful.
What does the red blinking key indicator mean?
This serves as a security system indicator. It alerts you to the immobilizer’s activation and the fact that the car won’t start without the right key (yours).
Why does a theft deterrent system activate?
Owners of motorcycles and automobiles value their assets highly. However, thefts of cars and motorcycles happen often in most nations around the world. Different techniques are employed by manufacturers to deter theft of motorbikes and automobiles. Unauthorized entry to a motorcycle or automobile is prevented by the use of an anti-theft alarm system or car alarm. Because of this, the makers add a security feature to keep someone else from using the product. They install numerous technologies in cars to make this easier.
How does the alarm system or Car Alarm work?
Sensors that are mounted in and around the car are used by the anti-theft alarm system to function. The sensors are activated by an impact or motions inside the vehicle. In turn, it sets off the alarm, which then sounds. The alarm finally sounds, alerting the owner or individuals. Even a slight shift in the posture of the car can cause the tilt sensor to alert and trigger the anti-theft alarm system.
Additionally, you can either install an aftermarket alarm or purchase a car from the manufacturer (OEM) with factory-installed alarms. The Remote Keyless Entry System, which aids in locking and unlocking doors and even starting engines, is typically included in OEM systems. Additionally, radio receivers, immobilizers, motion detectors, and wireless USB systems are all used in Remote Keyless Alarm systems. The Remote Keyless System uses strong cryptography authentication procedures as well.
