2002 Infiniti QX4
Top-Rated Licensed Key Service in Santa Barbara County

Q: Can you delete lost or stolen keys from my Infiniti so they no longer work?

Yes. When we program your Infiniti intelligent keys, the BCM registration process can wipe previously enrolled fobs and only register the ones physically present during the session. Any lost or stolen fob will no longer start your vehicle. Q50 owners dealing with repeated thefts describe the same Consult-based reprogramming procedure that thieves exploit being used legitimately to wipe stolen keys and add new ones. If a fob was stolen and you are worried about security, this is the right move and we can do it on site.

Q: Does my Infiniti intelligent key have a hidden emergency blade?

Yes. Most Infiniti intelligent keys have a hidden mechanical emergency blade inside the fob housing. You press a small release and slide the blade out. That blade fits the driver door lock cylinder, which is often hidden behind a small cap on the door handle. This lets you physically unlock the car when the fob battery dies or the intelligent key system is not responding. A mechanic confirmed this emergency key profile has been used on Nissan and Infiniti models since 2006.

Q: How many buttons does the 2002 Infiniti QX4 key have?

Your 2002 Infiniti QX4 key has 3 buttons. The button count helps confirm exactly which fob your vehicle uses, since Infiniti uses different key designs across intelligent key, proximity, and older non-proximity variants. When you call us, having this detail ready helps us verify the right key before we head to your location so there are no mismatches when we arrive.

Q: Should I get a spare made now while I still have a working key?

Absolutely. This is the single best way to protect yourself from a costly all-keys-lost situation later. When you have a working Infiniti key, adding a spare is a faster and less invasive OBD programming session. When all keys are lost, the BCM has to be accessed for PIN extraction and security reset, which takes longer, costs more, and carries higher risk on certain platforms. One Infiniti owner called the dealer price insane. Get a spare made now while it is easy and affordable.

🔧 PRO TIP

Infiniti uses Nissan's NATS immobilizer under the badge. If a locksmith is set up for late-model Nissan key work, your Q50, QX60, or G37 follows the same procedure with a different logo on the fob and the same 4-digit PIN system.

2002 Infiniti QX4 Transponder key Replacement - Fast, Affordable & Professional

BSIS license LCO#6792 means I passed California's background check, maintain active liability insurance, and operate a registered locksmith company. NASTF certification means I have access to the factory security database that provides key codes and immobilizer data unlicensed operators can't get. Google Guaranteed means Google verified my credentials independently.

A dermatologist at her clinic near Goleta Beach Park told me she'd verified my credentials before calling. She had a 2002 Infiniti QX4 and needed a spare smart key, but she'd heard about unlicensed operators damaging luxury car electronics. She wanted proof of legitimacy before anyone touched her Infiniti.

I used my Smart Pro to program her replacement fob through OBD. The Smart Pro runs the Infiniti security access sequence and learns new keys using the factory-supported PIN procedure. Her fob, FCC ID , was a -button smart key that I cut, programmed, and tested at the car. NASTF access matters on Infiniti because it provides the factory security codes the programming tools require.

Her spare cost 143. Dealer quoted 324. Real receipt, real license number, real phone number that works next month. You can look up LCO#6792 on the BSIS website right now.

Lost Your Infiniti QX4 Key? Here's What to Know

Everything about our mobile setup

What is the cheapest way to handle all-keys-lost on my Infiniti?▼

Call a mobile locksmith instead of the dealer. Infiniti dealers charge 350 to 500 or more for a single replacement key, and that is before towing. One owner on Reddit called the dealer price insane and was told a locksmith would handle it for around 100. We handle the entire AKL process on site at your 2002 Infiniti QX4 for a fraction of dealer pricing, no tow needed. If you want to save even more, get two keys programmed in the same session so you never end up in an AKL situation again.
