Step-by-Step Programming Instructions for Your 1999 Nissan Altima Key Fob
Follow these simple steps to program your 1999 Nissan Altima key fob. Make sure to read each step carefully before proceeding.
Step 1: Prepare Your Vehicle
Begin by ensuring all doors of your 1999 Nissan Altima are completely closed and locked. Use the driver’s side power lock/unlock switch located on the door panel to lock all the doors. This initial step is crucial for initiating the programming sequence.
Step 2: Ignition Key Cycling – Entering Programming Mode
This is the most critical step to get your Nissan Altima into programming mode. Take your key and insert it into the ignition. Immediately remove the key. Repeat this insert and remove action six times in rapid succession, all within a 10-second timeframe.

If you’ve successfully completed this step, the hazard lamps on your Nissan Altima will flash. This visual cue confirms that your vehicle has entered the key fob programming mode and is ready to learn the new remote signal.
Step 3: Turn Ignition to ACC Position
Now, insert the key back into the ignition cylinder and turn it to the “ACC” (Accessory) position. This position is just before the point where you would start the engine.
Step 4: Activate the Remote Transmitter
Within 5 seconds of turning the ignition to ACC, take your 1999 Nissan Altima key fob remote and press any button on it. You only need to press the button once. If successful, the hazard lamps on your Altima will flash again, indicating that the vehicle has recognized the signal from the key fob.

Step 5: Programming Additional Remotes (Optional)
If you have additional key fobs, including existing remotes you want to continue using, now is the time to program them. Without turning off the ignition, unlock and then lock all doors again using the driver’s side power lock/unlock switch. Within 5 seconds, press any button on the next remote transmitter you wish to program. The hazard lamps will flash to confirm successful programming of each additional remote. Repeat this step for every key fob you need to program.
Step 6: Finalize the Programming Sequence
To exit the programming mode, turn the ignition key to the “OFF” position and remove it from the ignition. Unlock the driver’s side door using the power lock/unlock switch and then open the driver’s side door. This sequence completes the programming procedure for your 1999 Nissan Altima key fob.
Troubleshooting Tips
If you encounter issues during the programming process, consider these points:
- Speed of Key Cycling: Ensure you are inserting and removing the key rapidly enough during Step 2, but also making sure to fully remove the key each time. If it’s too fast, the system might not register the cycles.
- Timing: Pay close attention to the timing in each step, particularly the 5-second windows in Steps 4 and 5.
- Remote Battery: Make sure the battery in your key fob is fresh and functioning correctly. A low battery can prevent the remote from transmitting a signal strong enough to be recognized during programming.
- Repeat the Process: If it doesn’t work the first time, carefully repeat all steps from the beginning. It’s easy to miss a step or timing requirement.
