Losing or damaging your key fob can be a major inconvenience. For 2010 Infiniti QX56 owners, the thought of dealership reprogramming fees might add to the stress. Fortunately, for keyless entry fobs, you might be able to program a new one yourself at home, saving both time and money. While new keys with immobilizer chips often require professional equipment, programming a key fob for remote locking and unlocking on your 2010 Infiniti QX56 can often be done with a simple in-car procedure.
This guide provides step-by-step instructions on how to program your 2010 Infiniti Qx56 Key Fob, allowing you to regain control of your vehicle’s keyless entry system without a trip to the dealer. Follow these instructions carefully to program your remote.
Step-by-Step 2010 Infiniti QX56 Key Fob Programming Instructions
Before you begin, ensure you have all your key fobs you wish to program with you. This procedure will erase all previously programmed fobs, so you’ll need to reprogram them all at once.
Step 1: Vehicle Preparation
Sit in the driver’s seat of your 2010 Infiniti QX56. Ensure all doors are closed and locked. This is crucial for initiating the programming sequence.
Step 2: Ignition Key Cycling
This step is the trigger to enter programming mode. Insert your key into the ignition cylinder and remove it more than six times within a 10-second period. It’s important to fully remove the key each time. You should see the hazard warning lamps flash twice to confirm that the system has entered registration mode.

Note: Speed is key, but ensure each key insertion and removal is distinct. If you perform this step too quickly, the system may not register the sequence and enter programming mode.
Step 3: Accessory Position
Insert the key back into the ignition cylinder and turn it to the ACC (Accessory) position. This powers the vehicle’s accessory systems without starting the engine, preparing it to receive the new key fob ID.
Step 4: Key Fob Button Press – First Remote
Take the first key fob you want to program. Press any button on the remote control once. The hazard warning lamps should flash twice again. This confirms that the system has accepted the ID code from this key fob. At this point, the oldest stored ID code is erased and replaced with the new one.

Step 5: Additional Remote Programming (Optional)
You can program up to four key fobs for your 2010 Infiniti QX56. If you only have one key fob to program, proceed to Step 9. If you have additional fobs, continue with the following steps.
Step 6: Lock Doors for Additional Fobs
To program subsequent key fobs, use the driver’s side power lock/unlock switch located on the door panel to lock all doors.
Step 7: Key Fob Button Press – Additional Remotes
Take the next key fob you want to program and press any button on the remote twice. The hazard warning lamps will flash twice to indicate successful programming of this additional fob. Again, the oldest ID code is erased and the new one is entered.
Step 8: Repeat for More Remotes
If you have more key fobs to program (up to a maximum of four), unlock the doors using the driver’s side power lock/unlock switch and repeat Step 6 and Step 7 for each additional remote.
Step 9: Completion and Testing
Once you have programmed all desired key fobs, open the driver’s side door. This action completes the programming sequence. Test the operation of each programmed remote to ensure they correctly lock and unlock the doors and activate other key fob functions for your 2010 Infiniti QX56.
Troubleshooting Tips
- Hazard Lamps Not Flashing: If the hazard lamps do not flash after Step 2, you may not have completed the ignition key cycling quickly enough, or the system might not be entering programming mode correctly. Try repeating Step 2, ensuring a slightly faster but distinct insertion and removal motion.
- Fob Not Programming: Ensure you are pressing a button on the key fob in Steps 4 and 7 immediately after the hazard lamps flash the second time in Step 2. Also, double-check that the key fob battery is functional.
- Procedure Timing: The timing of each step is important. If you are having trouble, try to follow the steps as smoothly and quickly as possible while still performing each action correctly.
When to Seek Professional Help
While this DIY procedure works for many 2010 Infiniti QX56 key fobs, there are situations where professional programming might be necessary.
- Immobilizer Issues: If you are programming a new key with an immobilizer chip (not just the fob for remote functions), professional programming with specialized equipment is typically required.
- Persistent Programming Failure: If you have carefully followed these steps multiple times and are still unable to program your key fob, there might be an issue with your vehicle’s receiver system or the key fob itself. In such cases, consulting a qualified locksmith or dealership technician is recommended.
By following these instructions, you can often successfully program your 2010 Infiniti QX56 key fob and regain convenient keyless entry functionality. This DIY approach can save you money and time compared to dealership programming, getting you back on the road quickly.
