Programming Instructions
This process will guide you through programming your 2003 Nissan Altima key fob quickly and efficiently. Make sure to follow each step precisely for successful programming.
-
Start by Ensuring All Doors are Locked: Manually lock all doors of your 2003 Nissan Altima using the power lock switch located on the driver’s side door panel. It’s crucial that all doors are securely locked before beginning the programming sequence.
-
Ignition Key Cycling: Insert your key into the ignition. The next step requires you to rapidly insert and remove the key from the ignition cylinder. Do this a total of six times within a 10-second timeframe. It’s important to fully remove the key from the ignition cylinder each time. If done correctly, your Nissan Altima’s hazard lamps will flash, indicating that the system has successfully entered programming mode. Note: Speed is key here, but ensure each insertion and removal is complete. If you perform this step too quickly or not completely, the system may not enter programming mode.
-
Turn Ignition to ACC: Insert the key back into the ignition and turn it to the “ACC” (Accessory) position. This is the position right before starting the engine.
-
Activate the Remote: Within 5 seconds of turning the ignition to ACC, press any button on the keyless remote you are programming. Once you press a button, the hazard lamps on your 2003 Nissan Altima should flash again. This confirms that the signal from the key fob has been received and the programming is in progress. Important: Press the button on the remote only once. Multiple presses may disrupt the programming sequence.
-
Programming Additional Remotes (Optional): If you have additional remotes to program, including existing remotes that you want to continue using, you must program them at this time as well. To program additional remotes, unlock and then lock all doors using the power lock switch on the driver’s door panel again. Within 5 seconds of locking the doors, press any button on the next remote. The hazard lamps will flash to confirm successful programming for each remote. Repeat this step for every remote you wish to program.
-
Finalizing Programming: Turn the ignition key to the “OFF” position and remove the key from the ignition. Unlock the driver’s side door using the power lock switch on the door panel and then open the driver’s door.
-
Test Your Remotes: Now, test all programmed key fobs to ensure they are working correctly. Try locking and unlocking your 2003 Nissan Altima using each remote’s buttons.
