Nissan Altima Key Fob

If you’re experiencing trouble with your Nissan Altima key fob, you’re not alone. Many Altima owners have faced similar issues, such as the key fob not working or being unresponsive. In this article, we will guide you through a step-by-step process to troubleshoot and potentially fix the problem.

Key Fob Battery Replacement

The first thing to check when encountering key fob issues is the battery. A low battery can cause the key fob to malfunction. Here’s how you can replace the key fob battery:

  1. Purchase a new battery suitable for your Nissan Altima key fob. For a 2011 Altima, a 2032 battery with a voltage of 3V should be compatible.
  2. Open the key fob using a small screwdriver or pry tool. Be careful not to damage the key fob casing.
  3. Locate the battery and remove the old one.
  4. Place the new battery in the designated slot, ensuring that the positive side is facing down.
  5. Close the key fob, making sure it is securely sealed.

After replacing the battery, test the key fob to see if the issue has been resolved. If not, there may be other factors contributing to the problem.

Key Fob Internal Inspection

If replacing the battery did not fix the issue, it’s time to inspect the internal components of the key fob. Follow these steps to perform an internal inspection:

  1. Open the key fob by using a screwdriver or pry tool, being cautious not to damage any internal components.
  2. Once opened, examine the area near the battery. Look for two prongs that should be touching a copper pad. If they are smashed or not properly aligned, the key fob will not receive adequate power.
  3. Additionally, check for four small prongs that should be in contact with the battery. Ensure they are straight and not bent or flattened. Adjust them gently if necessary.
  4. Pay attention to any bent tabs or loose connections within the key fob. If found, carefully reposition them to their correct positions.

Taking these steps can potentially fix the key fob issue without having to replace the entire fob unit, which can be costly.

Avoiding Costly Repairs

Before resorting to replacing the key fob, consider attempting to fix it yourself. If the internal inspection and adjustments do not resolve the issue, contacting a Nissan dealership is the next option. However, keep in mind that Nissan may recommend replacing the entire key fob unit, which can cost around $200 or more.

By taking the time to inspect and make minor adjustments to the key fob, you may be able to avoid unnecessary expenses. Remember to handle the key fob gently during the inspection process to prevent any damage.


Troubleshooting a malfunctioning Nissan Altima key fob can be an easy task if you follow the steps outlined in this article. By replacing the battery and inspecting the internal components, you may be able to resolve the issue without incurring repair costs from a dealership.

It’s always worth trying to fix the key fob yourself before seeking professional help. However, if you are unable to resolve the issue, don’t hesitate to contact a Nissan dealership for further assistance. Your key fob is an essential component to access and operate your Nissan Altima, so ensuring it works properly is a priority for a smooth driving experience.

Remember, if you’re unsure about taking apart the key fob yourself, it’s best to seek professional help to avoid any potential damage.
