Infiniti Key Fob Programming: Fast Locksmith Services
Published Date: Nov 21, 2025
Click — and nothing? If your fob won’t unlock the doors or start the engine, you’re likely due for a quick reset or a newly programmed key. On older key-ignition Infiniti vehicles, a simple lock-and-ignition sequence can bring the remote back to life. On newer push-to-start models, Infiniti key fob programming usually requires a professional with dealer-level OBD-II tools. This guide from Sure Lock & Key shows the steps for common models and helps you decide when it’s time to call in a technician.
Infiniti Key Fob Programming for Older Key-Ignition Models
Infiniti G35 key fob programming and similar procedures for older models like the FX35 or M35 can often be done manually without expensive diagnostic computers. These cars let the onboard computer enter a “learning mode” using a short sequence.
Secure the cabin.
Close all doors. Use the driver’s power lock switch to lock, then unlock.Cycle the ignition.
Insert the key and remove it completely 6–10 times within about 10 seconds.Watch for signals.
Stop when the hazard lights flash. That means the car is ready to reprogram the Infiniti key fob signals.Accessory mode.
Insert the key again and turn to ACC.Sync the remote.
Press any button on the new fob. The hazards should flash to confirm pairing.Finish.
Turn the key OFF and unlock the driver’s door to exit programming mode.
If the sequence doesn’t trigger hazards, the door lock actuator may be weak, or an aftermarket fob may be the wrong frequency. In those cases, call a car locksmith for help.
Infiniti Smart Key Programming for Push-to-Start Models
Newer vehicles utilize advanced encryption that makes the manual “key dance” obsolete. Infiniti Q50 key fob programming, for example, involves complex communication between the Intelligent Key and the car’s body control module (BCM).
Resyncing vs. Programming
- Resyncing (battery died): If you’re searching for how to reset the Infiniti Q50 key fob after a dead battery, press the fob’s logo side against the Start/Stop button while holding the brake. This often lets the car recognize the chip and start, so you can drive and then arrange service.
- New key addition: Adding a brand-new fob usually requires OBD-II programming so the immobilizer can authorize the transponder. This is standard Infiniti smart key programming and is best handled by a professional.

Troubleshooting & When DIY Won’t Work
Sometimes, despite following the manual steps perfectly, the hazard lights never flash, or the push-button start refuses to recognize the device.
- Infiniti QX56 key fob not working: If the vehicle won’t enter programming mode, the door lock actuator may be weak or failed, which prevents the BCM from confirming steps.
- Aftermarket fobs: Cheap generics may not match the RF spec (radio-frequency specification) your car expects, causing Infiniti G37 key fob programming attempts to fail.
- System lockouts: Too many failed attempts can trigger a temporary immobilizer lock. You’ll need dealer-grade or professional equipment to clear it.
When you hit these walls, Sure Lock & Key can connect with CONSULT-level or equivalent tools and complete Infiniti car key programming safely.
Ready to Program Your Infiniti Key Fob?
Whether you’re driving a classic G35 or a late-model QX80, working keys keep you secure and on schedule. For older key-ignition models like the G35, M35, and FX35, start with the manual door-lock and ignition cycle. Push-to-start platforms such as the Q50, QX60, and Q60 typically need OBD-II programming, and a manual resync only helps after a dead battery. If you’ve lost all your keys, a locksmith will cut an emergency blade, program the transponder, and then pair the fob. For fast mobile help, book Infiniti key fob programming with Sure Lock & Key. Our technicians come to you, verify every function, and get you back on the road.
Frequently Asked Questions
