How To Reset A Key Fob After Changing The Battery

How to replace battery in Nissan key fob

Vehicle key fobs, commonly called electronic car keys, are used to start a car remotely and open its doors. Signal loss can cause the car key fob to malfunction over time, necessitating reprogramming to continue using the device.

However, a key fob may only require reprogramming if not functioning correctly. If a car owner follows the straightforward, step-by-step instructions below, they can accomplish this without an auto locksmiths assistance:

  • Utilizing the Lock Switch on the drivers side door, get inside your Nissan and lock all the doors.
  • Insert the key into the ignition and remove it. In precisely 10 seconds, repeat these 6 times. Before putting it back, please remove it from the ignition completely. Avoid turning the key.
  • You have now entered programming mode. Both the interior and outside lights will flash twice when this is done.
  • Re-insert the key into the ignition after leaving the programming mode and turn it to the start position.
  • Just once, press any key on the key fob. Dont give it a second try.
  • The key fob should be programming mode if the previous stages have gone as planned. The hazard lights would flash as confirmation of the reprogramming.
  • Unlock your doors, remove the key fob from the ignition, and exit the car.
  • Try locking the door and using the key fob to unlock it.

If the initial steps do not work, try again. Reach the closest Nissan dealership if your attempts to reprogram the car repeatedly fail.

    Background: What Functions Are On A Nissan Key Fob

    First lets be clear on the key fobs themselves. Broadly speaking, there are two versions that are still commonly in use in 2021. There is a simpler, 4-button key fob that simply locks and unlocks the car, as well as opens the trunk and includes a panic alarm, too. The newer generation added a remote start button, bringing the total to 5 buttons. They also introduced a blinking light that indicates the battery is working and power is flowing in the key fob.

    The 5-button key fob also helps the Nissan owner manage certain security functions on their vehicle. Its primarily designed to be a fob that just sits in your pocket or purse and allows you to open and lock the doors keylessly, as well as start the car.

    The effective range of these keyless features is about 2.5 feet. A button on the door handle can lock and unlock the car when the fob is close, and the cars push-button start will activate only when the key fob is close, too.

    A family running a Nissan vehicle together can register up to 4 keys on each car. The key fobs are saved as profiles in the Nissan infotainment system and can be used to allow drivers to create and save their own personal settings which are then activated when the key fob opening and starting the car is identified.

    What Happens If My Key Fob Dies While Driving

    However, you will not be able to lock or unlock your doors, open the trunk, or set the alarm with the key fob. Youll still be able to start the car and drive it without any issues.
