How to Program a Spare INFINITI Key Fob: Complete Guide

Programming a spare key fob for your INFINITI allows you to maintain convenient access to your vehicle while protecting its security. Whether you’ve purchased a new fob or need a replacement, this comprehensive guide walks you through the steps, tips, and troubleshooting to ensure your spare fob works seamlessly with your INFINITI.

What is an INFINITI Key Fob?

The INFINITI key fob is a wireless remote that controls door locks, trunk release, and ignition functions for push-button start vehicles. It communicates securely with your car’s onboard computer using encrypted signals, making proper programming essential for functionality.

Signs You Need to Program a Spare Key Fob

• You’ve purchased a new or replacement key fob.
• Your existing fob is lost, damaged, or malfunctioning.
• You want an additional spare fob for family members or backup purposes.

INFINITI Models That Require Programming

Programming procedures vary slightly by model. Common INFINITI vehicles include:

• QX80, QX60, QX55 – often push-button start vehicles with encrypted fob programming
• Q50, Q60 – may allow manual programming or dealer-assisted programming depending on year
• Older INFINITI models – may support manual programming through ignition sequences

Step-by-Step Guide to Program a Spare INFINITI Key Fob

Follow these steps carefully. Note that certain newer INFINITI models may require dealer programming due to advanced encryption.

1. Prepare the Vehicle: Ensure all doors are closed and the ignition is off. Remove all keys from the vehicle.
2. Enter Programming Mode: Insert the existing key into the ignition and turn to the “ON” position (do not start the engine). In some models, press the “Lock” button on the fob while holding the existing key in place.
3. Program the Spare Fob: Press the “Lock” and “Unlock” buttons simultaneously on the new fob for 5–10 seconds until the hazard lights flash or you hear a chime indicating successful programming.
4. Confirm Functionality: Test all fob functions: lock, unlock, trunk release, and push-button start (if applicable). Ensure the vehicle responds consistently.
5. Exit Programming Mode: Turn the ignition off, remove the key, and test both the original and spare fobs to ensure proper operation.

Troubleshooting Common Issues

• Spare fob doesn’t work: Confirm battery is installed correctly and is fully charged.
• Vehicle doesn’t enter programming mode: Check that doors are closed and ignition is in the correct position.
• Multiple fobs needed: Some vehicles allow only a limited number of fobs to be paired. Remove old fobs if necessary.
• Persistent errors: For push-button start models, dealer programming with specialized diagnostic tools may be required.

Tips for Success

• Always use an official INFINITI replacement fob to ensure compatibility.
• Have a fully charged key fob battery before attempting programming.
• Keep your original key fob in case of programming failure.
• Read your owner’s manual for model-specific instructions and fob limitations.
