Lost your Nissan key fob or need to replace the battery? Don't worry; you can reprogram your key fob yourself without a trip to the dealership. This guide will walk you through the simple process of reprogramming a Nissan push-start key fob.

Before You Begin

• Compatibility: Ensure your Nissan model is equipped with the push-start system. This guide applies to most newer models but consult your vehicle's manual for any model-specific variations.
• Battery: Make sure the key fob has a fresh battery installed. A weak battery can interfere with the reprogramming process.
• All Fobs: To avoid any conflicts or additional resets later, make sure you have all the key fobs you want to use with the vehicle available for this procedure.

Reprogramming Procedure

1. Get in the Driver's Seat: Enter your Nissan and sit in the driver's seat with all doors closed.
2. Insert the Key Fob: Locate the key fob slot (often near the steering wheel or center console) and insert the key fob you wish to program.
3. Cycle the Ignition: With your foot OFF the brake pedal, press the "Start/Stop" button once to turn the ignition to the "ACC" position, then again to the "ON" position. Repeat this "ACC-ON-ACC-ON" cycle, ending in the "OFF" position.
4. Re-Insert the Key Fob: Within 10 seconds of turning the ignition "OFF," quickly remove and re-insert the key fob into the slot.
5. Press "Start" and Lock: Immediately after reinserting the key fob, press the "Start/Stop" button once to turn the ignition to the "ON" position. Then, within 5 seconds, press and hold the "LOCK" button on the key fob for several seconds.
6. Confirmation: If successful, the hazard lights should blink twice. Turn the ignition "OFF" and remove the key fob.

Test and Repeat

Test your newly programmed key fob by starting the car. If unsuccessful, repeat the process carefully, being mindful of the timing for each step. If you have another key fob to program, repeat the entire process for that key, starting with getting in the driver's seat.

Troubleshooting

• Vehicle Doesn't Respond: Ensure you followed the instructions for your specific Nissan model. Refer to your vehicle manual.
• Battery is Fresh: A fully depleted battery in the fob can hinder this process.
• Professional Assistance: If multiple attempts remain unsuccessful, reaching out to your Nissan dealership or a qualified locksmith may be necessary.
