Losing or needing to replace your Infiniti key fob can be a frustrating experience. Fortunately, you might be able to reprogram a new or existing key fob yourself, saving you a trip to the dealership. This guide provides a simple, step-by-step process to reprogram your Infiniti key fob, allowing you to regain access and control of your vehicle quickly.
Step-by-Step Guide to Reprogramming Your Infiniti Key Fob
Before you begin, ensure you have all key fobs you wish to program with you, as you will need to program them all during this process. Follow these steps carefully to reprogram your Infiniti key fob:
-
Prepare for Programming: Sit in the driver’s seat of your Infiniti and ensure all doors are completely closed. Once seated, use the power lock switch located on the driver’s side door to lock all doors. This initial step is crucial for initiating the programming sequence.
-
Initiate the Programming Sequence: Locate the push-button ignition start. Without pressing the brake pedal (to avoid starting the engine), press the start button and release it repeatedly, at least six times within a 10-second timeframe. Make sure each press is a full push and release. If this step is performed correctly, you should observe the hazard lights of your Infiniti flashing. This flash indicates that your vehicle has entered the key fob programming mode.
-
Enter Accessory Mode: After the hazard lights flash, press the start button one more time, again without pressing the brake pedal. This action will turn the vehicle’s ignition to the “accessories” setting, which is necessary for the next step in programming your key fob.
-
Program the First Key Fob: Take the key fob you wish to program first. Within five seconds of entering accessory mode, press any button on the key fob. If the programming is successful for this key fob, the hazard lights will flash again. This flash confirms that the first key fob has been successfully programmed into your Infiniti’s system.
-
Program Additional Key Fobs (if applicable): If you have more key fobs to program, including any previously programmed fobs you want to continue using, you must program them now. To program subsequent key fobs, use the power lock switch on the driver’s side door to first unlock and then immediately lock all the doors. Within five seconds of locking the doors, press any button on the next key fob you wish to program. Again, a flash of the hazard lights will indicate successful programming for each additional key fob. Repeat this step for every key fob you need to program. It’s important to reprogram all desired key fobs, including any previously working ones, in this session as the system may clear old codes.
-
Exit Programming Mode: To finalize the programming process and exit the programming mode, turn the ignition to the “Off” position. You can do this by briefly pressing the start button again (without pressing the brake pedal). Once the ignition is off, unlock the doors using the driver’s-side power lock button and open the driver’s door to fully exit the programming sequence.

Troubleshooting and Important Considerations
If you encounter issues during the reprogramming process, consider the following:
- Timing is crucial: Ensure you are performing each step within the specified timeframes, particularly the 5-second window after entering accessory mode and locking the doors.
- Battery condition: Make sure the batteries in your key fobs are new and have sufficient charge. Low battery power can sometimes interfere with the programming process.
- Correct procedure: Double-check that you have followed each step accurately. Reread the instructions and try again, paying close attention to each detail.
- Vehicle Compatibility: While this procedure is generally applicable to many Infiniti models, there might be slight variations depending on the year and specific model. Consult your vehicle’s owner’s manual for the most accurate instructions for your particular Infiniti.
If you are still unable to reprogram your Infiniti key fob after several attempts, it is recommended to seek assistance from a certified Infiniti dealership or a professional automotive locksmith. They have specialized tools and diagnostic equipment to handle key fob programming and can address more complex issues.
Reprogramming your Infiniti key fob yourself can be a convenient and cost-effective solution. By following these steps carefully, you can often restore the functionality of your key fobs and maintain seamless access to your vehicle.
