But lucky for you, they have a simple key programming kit available from their website,, that allows you to program a new fob or key for your Nissan or Infinity vehicle in just 15 minutes. In this article, we will guide you through the step-by-step process of using this kit to program your Nissan Altima key fob easily.

Getting Started with the Simple Key Programming Kit

Once you’ve ordered the key programming kit from, it will be delivered to your doorstep within a few days. In the box, you will find a user guide that provides important instructions for the programming process. Before you begin, ensure that your vehicle’s battery is fully charged and all power-consuming features such as headlights, air conditioning, heater, radio, and other lights are turned off. This is to prevent any battery drainage during the programming process.

Step 1: Fob Activation

There are two steps involved in programming your key fob. If you have ordered additional fobs separately, they may not require the activation step, whereas the fobs that come in the kit will require activation. To activate the fob, you need to find your vehicle’s model in the lookup table provided in the user guide. For example, if you have a Nissan Altima 2015 with a four-button remote and trunk, you will need code 42.

To activate the fob, press and hold the top and bottom buttons simultaneously. When a solid blue light appears, it indicates that you need to proceed with the activation process. Be cautious as there is a time limit for entering the code, and if you wait too long, the activation process will time out, and you’ll have to start over.

Using the top button on the fob, enter the number four, then use the second button to enter the code 21234. After entering the code successfully, press and hold the bottom button on the fob for about two seconds. The fob will flash back the code, confirming successful activation. In this case, the code entered was 42, indicating that the fob is now activated for the 2015 Nissan Altima.

Step 2: Programming Process

The next step is the programming process, which involves turning the ignition to dial position number seven with the vehicle turned off. Locate the OBD2 port near the brake and gas pedal in your vehicle. Plug in the key programmer, and you’ll hear a beep to confirm the connection.

Follow the instructions in the user guide for the programming process. There will be commands such as “hold to confirm,” which means you need to press and hold the button for about two seconds. Keep in mind that the user guide will provide detailed instructions specific to your vehicle’s make and model.

Pairing the Key Fobs

Now, let’s pair the key fobs with your Nissan Altima. If you already have a working key fob, it will be used as a reference during the programming process. Open and close the door, then turn on the hazard lights as instructed. The next step is to press and hold the start button until the dash lights turn on. Once the lights have turned on, release the button.

Follow the on-screen instructions for communicating with the vehicle and turn off the ignition when prompted. Press the start button on the remote, and you’ll notice the security light blinking on the dashboard. This indicates that the key fob is successfully paired. Continue following the instructions to complete the pairing process for multiple key fobs.

Completing the Programming Process

After pairing the key fobs, you’ll proceed with turning off the ignition and unplugging the installer from the OBD2 port. Move the key fobs away from your vehicle and attempt to start the vehicle using the newly programmed key fob. If it works, congratulations! Your programming process is complete.

Troubleshooting Tips

In case none of your key fobs are working after programming, there are troubleshooting steps you can take. One common issue is when the dashboard lights fail to illuminate around the push button start. This can be resolved by checking if the fuse titled “push button start” has been removed or burnt out. If so, replace the fuse to restore functionality to the original key fob.
