Lost your 1998 Nissan Altima Key Fob or need to program a new one? Don’t worry, programming your key fob for your 1998 Nissan Altima can be a straightforward process you can do yourself. This guide will walk you through the steps to get your keyless entry system working again, drawing upon official Nissan service procedures to ensure accuracy and reliability.
This guide is specifically for the 1998 Nissan Altima (L30) and may also apply to other Nissan models from the same era, including the Frontier, Maxima, Pathfinder, and Sentra of similar years. However, always verify compatibility with your vehicle’s specific year and model.
Before you begin, it’s important to confirm a couple of things:
- Remote Controller Function: Not all trim levels of the 1998 Nissan Altima came equipped with keyless entry. Check your original vehicle documentation or sales brochure to confirm if your Altima has this feature.
- Correct Remote: Ensure that the key fob you are trying to program is the correct type for your 1998 Nissan Altima. Using an incompatible remote will prevent successful programming.
If you’ve confirmed these points, you’re ready to proceed with programming your 1998 Nissan Altima key fob. Follow these steps carefully:
Step-by-Step Programming Procedure for Your 1998 Nissan Altima Key Fob
This procedure is designed to program your key fob without the need for any special tools.
-
Get Inside and Lock Up: Enter your 1998 Nissan Altima and close all doors. Make sure all doors are fully closed. Then, using the power door lock switch on the driver’s side door, lock all the doors.
-
Ignition Key Cycling: This is a crucial step that puts your Nissan Altima into programming mode. Insert your ignition key into the ignition cylinder and remove it more than six times within a 10-second period. It’s important to maintain a rhythm of approximately one insertion and removal cycle per second. Make sure to fully remove the key from the ignition cylinder each time. Do not rush this step.
-
Turn Ignition to ACC: After the key cycling, turn the ignition key to the “ACC” (Accessory) position. Leave the key in the “ACC” position for the remainder of the programming process, including programming any additional remotes.
-
Press a Button on the Remote: Take the key fob you want to program and press any button on it one time only. It’s critical to only press the button once. Pressing it more than once in this step will disrupt the programming sequence and it will not be successful.
If this step is completed correctly, the hazard warning lights on your 1998 Nissan Altima should flash twice. This double flash indicates that the key fob has been successfully programmed.
-
Programming Additional Remotes (Optional): If you have more than one key fob to program for your 1998 Nissan Altima (up to a maximum of 4), you can program them now.
a. Unlock and Lock Doors: After successfully programming the first remote, and while still inside the vehicle with the ignition in the “ACC” position, use the driver’s side power door lock switch to unlock and then lock the doors again.
b. Press Button on Additional Remote: Take the next key fob you wish to program and press any button on it one time only. Again, ensure you only press the button once.
The hazard warning lights should flash twice again, confirming successful programming of the additional remote. Repeat steps 5a and 5b for any further remotes you need to program, up to the 4-remote limit.
-
End Programming Sequence: Once you have programmed all desired key fobs, it’s time to exit the programming mode.
a. Remove Key from Ignition: Turn the ignition off and remove the key from the ignition cylinder.
b. Unlock Doors and Open Driver’s Door: Use the power door lock switch on the driver’s door to unlock the doors. Then, open the driver’s side door. Opening the driver’s door is the final step to conclude the programming sequence.
-
Test Your Remotes: Finally, test each of your newly programmed key fobs to ensure they are working correctly. Use each remote to lock and unlock the doors of your 1998 Nissan Altima. If the doors lock and unlock as expected with each remote, then the programming process has been successful.
Important Notes and Considerations
- Timing is Key: The timing of the key insertion and removal in step 2 is important. Maintain a consistent pace of about one cycle per second and avoid rushing.
- One Button Press: In steps 4 and 5b, pressing the remote button only once is crucial. Multiple presses will interrupt the process.
- Maximum Remotes: You can program up to a maximum of 4 key fobs for your 1998 Nissan Altima.
- Simultaneous Programming (for some models): For some older Nissan models (specifically pre-2000 models mentioned in the original bulletin excluding 2000 Altima), if you have multiple remotes, they might need to be programmed all at the same time during a single programming sequence. However, for the 1998 Nissan Altima, the procedure outlined above allows for adding remotes sequentially.
- Warranty and Reprogramming: Keep in mind that according to Nissan service information, reprogramming a functioning remote or programming additional remotes is typically not covered under warranty. Also, issues arising from remote damage or battery replacement are not warranty items.
By following these steps carefully, you should be able to successfully program your 1998 Nissan Altima key fob and regain the convenience of keyless entry. If you encounter difficulties, double-check each step and ensure you are using a compatible remote for your vehicle. If problems persist, consulting a professional automotive locksmith or Nissan dealership might be necessary.
