A Nissan key fob is indispensable for modern vehicle owners, offering remote access to lock and unlock doors, and even start the engine from a distance, especially with push-start ignition systems. If you find yourself needing to reprogram your Nissan push start key fob, whether due to battery replacement, purchasing a new fob, or encountering unexpected malfunctions, this guide provides a straightforward, step-by-step process to get you back on track.
Why Reprogram Your Nissan Key Fob?
Reprogramming your Nissan push start key fob might become necessary in several situations:
- Battery Replacement: While not always required after a simple battery change, sometimes the system might lose sync, necessitating a reprogramming.
- New Key Fob: If you’ve purchased a replacement key fob, it won’t automatically communicate with your Nissan. Reprogramming is essential to pair the new fob with your vehicle’s system.
- Malfunction or Desynchronization: Occasionally, due to electronic glitches or system errors, your key fob might stop working correctly or become desynchronized with your car. Reprogramming can often resolve these issues.
Understanding when and why reprogramming is needed is the first step. Now, let’s delve into how to reprogram your Nissan push start key fob.
Step-by-Step Guide to Reprogramming Your Nissan Push Start Key Fob
While specific steps can slightly vary depending on your Nissan model and year, the following general method often applies to many Nissan vehicles with push start systems. Always consult your owner’s manual for the most accurate instructions for your specific car.
Step 1: Get Inside Your Nissan and Close All Doors
Begin by entering your Nissan and ensuring all doors, including the trunk or hatch, are completely closed. This ensures the system is properly set for programming mode.
Step 2: Locate the Ignition Button and Have Your Key Fob Ready
For push-start systems, the ignition switch is typically a button located on the dashboard or steering column. Have your Nissan push start key fob readily available in your hand.
Step 3: Initiate Programming Mode – The Key Cycling Method
This method involves using the ignition button and door lock switch to enter programming mode.
- Enter and Sit in the Driver’s Seat: Ensure all doors are closed.
- Cycle the Ignition: Press the push start ignition button quickly six times within 10 seconds. You should only press it enough to turn the ignition to the ‘ON’ position (without starting the engine) and then off each time. Do this rapidly.
- Open and Close Driver’s Door: Immediately after the ignition cycling, open and then close the driver’s side door once.
- Cycle Ignition Again: Press the ignition button one more time to turn it to the ‘ON’ position. At this point, the hazard lights should flash to indicate that your Nissan has entered programming mode. If the hazard lights don’t flash, repeat steps 1-4.
Step 4: Program the Key Fob
Once in programming mode (hazard lights flashing), proceed to program your Nissan key fob:
- Press and Hold Unlock Button: On your key fob, press and hold the ‘UNLOCK’ button and simultaneously press the ‘LOCK’ button six times while still holding ‘UNLOCK’.
- Release Both Buttons: Release both buttons on the key fob.
- Confirmation: The hazard lights should flash again to confirm that the key fob has been successfully programmed. If you have additional key fobs to program, repeat steps 1 and 2 of this step for each fob within the programming session.
Step 5: Test the Reprogrammed Key Fob
Exit programming mode by opening the driver’s door. Test all the buttons on your newly programmed Nissan push start key fob to ensure they are functioning correctly. Try locking and unlocking the doors, and if your fob has a remote start feature, test that as well.
Troubleshooting Tips
If you encounter issues while attempting to reprogram your Nissan key fob, consider these troubleshooting tips:
- Check Battery: Ensure the battery in your key fob is new and correctly installed. A weak battery can hinder the programming process.
- Follow Manual: Refer to your Nissan owner’s manual for model-specific instructions, as there might be slight variations in the procedure.
- Timing is Key: The timing of ignition cycling and button presses can be crucial. Practice the steps to ensure you are performing them quickly and accurately.
- One Fob at a Time: If programming multiple fobs, try programming them one at a time to avoid potential interference.
- Seek Professional Help: If you’ve tried these steps and still cannot reprogram your key fob, there might be an underlying issue with your vehicle’s immobilizer system or the key fob itself. In such cases, it’s best to consult a certified Nissan dealership or a qualified automotive locksmith for professional assistance.
Reprogramming your Nissan push start key fob can often be accomplished at home with these steps. By following this guide, you can regain full functionality of your key fob and the convenience it offers.
