Step-by-Step Process

Step 1: Remove the Emergency Key from the Smart Key

To begin, you need to remove the emergency key from the smart key. Look for a release button on the back of the smart key and press it. The emergency key will slide out easily. Make sure to keep it safely nearby, as you will need it in the next step.

Step 2: Unlock the Driver’s Door Using the Emergency Key

Take the emergency key you just removed and insert it into the keyhole on the driver’s door. Turn the key to the left or counterclockwise to unlock the door. This step ensures that you can gain access to the vehicle even if the key fob is not functioning due to a dead battery.

Step 3: Silence the Alarm by Starting the Vehicle

Once you have unlocked the driver’s door, be prepared for the alarm to sound. To stop the alarm, you will need to start the vehicle. While this may seem tricky with a dead key fob, it is actually quite simple. Get inside the Altima and press the key fob against the stop-start button. This will allow you to start the vehicle as you normally would. Press the brake pedal and touch the key fob against the stop-start button. The alarm will stop and you can proceed to start the vehicle without any issues.

Step 4: Adapting to a Dead Key Fob or Vehicle Battery

It is important to note that if your vehicle’s battery is also dead, you don’t have to worry about the alarm going off. Without power, the alarm system will not be activated when you open the door. Simply follow the steps mentioned above to unlock the door using the emergency key and start the vehicle as usual.

Conclusion

In conclusion, we have learned how to unlock, open, and start a Nissan Altima from 2019 to 2023 when faced with a dead key fob battery. By removing the emergency key from the smart key, unlocking the driver’s door, and starting the vehicle using the key fob against the stop-start button, you can effortlessly regain control of your Altima.
