This guide provides simple, step-by-step instructions on how to program a 2003 Nissan Xterra key fob, allowing you to regain remote access to your vehicle quickly and easily.
Step-by-Step Guide to Program Your 2003 Nissan Xterra Key Fob
Follow these instructions carefully to successfully program your 2003 Nissan Xterra key fob. It’s important to perform each step accurately for the programming sequence to work.
-
Prepare Your Vehicle: Begin by getting inside your 2003 Nissan Xterra. Ensure all doors are closed and locked. Use the manual lock/unlock switch located on the driver’s side door to lock all doors. Do not use the remote for this step.
-
Ignition Key Insertion Sequence: Take your ignition key and insert it into the ignition switch. Quickly remove the key from the ignition a total of 6 times within a 10-second period. Make sure each insertion and removal is a complete cycle, done rhythmically at roughly one-second intervals. If performed correctly, the hazard lights should flash, indicating the system has entered programming mode. If the hazard lights do not flash after 6 attempts, try repeating the process up to 10 times.
-
Enter ACC Position: Once the hazard lights have flashed, insert the key back into the ignition switch and turn it to the “ACC” (Accessory) position. This is the position right before starting the engine.
-
Program the First Remote: Within 5 seconds of turning the key to the ACC position, take the new key fob you wish to program and press the “lock” button once. If the programming is successful for this remote, the hazard lights should flash again to confirm.
-
Program Additional Remotes (Optional): If you have more remotes to program, including both new and existing working remotes, you can program them at this stage. If you only have one remote to program, proceed to step 6. To program additional remotes, first use the manual lock/unlock switch on the driver’s side door to unlock and then immediately lock the doors again. Do not use the remote for this step. Within 5 seconds of locking the doors manually, press the “lock” button on the next remote you want to program. The hazard lights will flash to confirm successful programming of each additional remote. Repeat this process for all remaining remotes you wish to program.
-
Exit Programming Mode: After you have programmed all desired remotes, turn the ignition switch to the “OFF” position. Completely remove the key from the ignition.
-
Unlock Doors Manually: Use the manual lock/unlock switch on the driver’s side door to unlock all doors. Do not use the remote for this step.
-
Test Your Remotes: Finally, test all programmed remotes to ensure they are working correctly. Press the lock and unlock buttons on each remote to verify they now control the door locks of your 2003 Nissan Xterra.
