Have you ever found yourself locked out of your Infiniti or dealing with a key fob that suddenly stopped working? Fortunately, programming your Infiniti key fob can often be done yourself, saving you a trip to the dealership. This guide provides a straightforward, step-by-step process to reprogram your Infiniti key fob for a range of models.
Before you begin, ensure you have your Infiniti key and all the key fobs you wish to program. This procedure will erase all previously programmed key fobs, so you’ll need to reprogram them all at once. Let’s get started with programming your Infiniti key fob.
Step-by-Step Infiniti Key Fob Programming Instructions
Follow these steps carefully to successfully program your Infiniti key fob:
-
Close and Lock All Doors: Begin by ensuring all doors, including the trunk or hatch, are fully closed. Then, lock all doors using the power lock switch on the driver’s side door.
-
Ignition Key Cycling: This step is crucial and requires precise timing. Insert and remove your key from the ignition cylinder rapidly, more than six times within a 10-second timeframe. Make sure to fully remove the key from the ignition cylinder each time.
- Note: The hazard warning lamps should flash if this step is performed correctly. Pay attention to the timing and ensure complete insertion and removal of the key each cycle. If successful, you may also notice the side marker, tail, license plate lamps, and interior lights flash twice. This visual confirmation indicates the system has entered programming mode.
-
Turn Ignition to “AAC”: Immediately after the hazard lights flash, insert the key back into the ignition cylinder and turn the ignition switch to the “AAC” (Accessory) position. Do not start the engine. At this point, the system is ready to learn the new key fob ID codes, and any previously stored codes are erased for security reasons.
-
Press a Button on the New Remote: Take the new key fob you want to program and press any button on it once.
- Important: Press the button only once. Pressing it multiple times can disrupt the programming sequence. Upon successful programming of this key fob, the hazard warning lamps should flash again to confirm. You might also see the side marker, tail, license plate lamps, and interior lights flash twice as a visual confirmation of successful programming.
-
Additional Key Fob Programming (If Applicable): If you have more than one key fob to program, you’ll need to repeat this step for each additional fob. To program another key fob, first release the door lock and then lock it again using the power door lock/unlock switch located on the power window main switch panel on the driver’s side door. After locking the doors again, immediately repeat step 4 with the next key fob you wish to program.
-
Finalize Programming: Once you have programmed all desired key fobs (up to a maximum of four), remove the key from the ignition cylinder.
-
Unlock and Open Driver’s Door: Unlock the driver’s side door, open the driver’s side door, and then close the door. This action completes the programming sequence.
- End of Programming: Your Infiniti key fob programming is now complete. Test each key fob to ensure it correctly locks and unlocks the doors and activates other remote functions.

Note: This programming procedure is designed to accommodate up to four key fobs. Any attempts to program more than four will be ignored by the system.
By following these steps, you should be able to successfully program your Infiniti key fob and regain full remote access to your vehicle. If you encounter any difficulties, double-check each step and ensure you are performing them in the correct sequence and within the specified timeframes. If problems persist, consulting your Infiniti owner’s manual or contacting a qualified automotive locksmith or Infiniti dealership may be necessary.
