🔧 PRO TIP
The 1999 QX4 runs Nissan's transponder-based immobilizer system, same architecture shared with several late-90s Nissan and Infiniti vehicles. The transponder chip in the key head has to be registered to the vehicle's immobilizer control unit before the engine will stay running. A lot of people cut a new key blade, try it in the ignition, and it turns fine but the engine cranks and immediately dies. That's not a mechanical problem. That's the immobilizer not recognizing the chip. The blade alone does nothing without the chip being enrolled. Also worth knowing: on these late-90s systems, you don't need factory security data credentials or a dealer-only tool to do the programming. The procedure is well within reach of proper automotive locksmith equipment through the OBD port.

1999 Infiniti QX4 Transponder Key Replacement - Fast, Affordable & Professional

I was parked near the Seacoast neighborhood in Imperial Beach when the call came in. Owner of a 1999 Infiniti QX4, sitting in the driveway of a place off Seacoast Drive. He'd had a key cut at a hardware store weeks earlier, used it every day, no problem. Then one morning the engine cranked, fired for a second, and died. Tried it four more times. Same result every time. He thought the car had developed some kind of fuel or electrical problem overnight.

He called a shop first. They told him it sounded like a fuel pump. He was about to schedule a diagnostic when somebody in a forum thread mentioned that his exact symptom, cranks and immediately stalls, points to the immobilizer rejecting the key, not a mechanical failure. That's when he called me.

I got there and he showed me the key. Blade was cut correctly, turned smooth in the cylinder. But when I looked at the key head, it was a plain copy. No chip. Whoever cut it had used a standard metal blank instead of a transponder-equipped one. The original key, which he still had, started the car without hesitation.

I cut a proper replacement key using the correct transponder-equipped blank, enrolled the chip to his immobilizer through the OBD port, and tested it. Started clean on the first try. He'd been one diagnostic fee away from pulling a perfectly good fuel pump for no reason.

The whole job wrapped up in his driveway. He didn't need a tow, didn't need to wait days for a dealer-ordered key.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Infiniti QX4 Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys to my 1999 Infiniti QX4. Can you still make one?
Yes. All-keys-lost on the 1999 QX4 is a manageable job. The immobilizer on these late-90s systems allows new key enrollment through the OBD port using the right equipment. I access the vehicle's security data, generate a working key, cut the blade to your specific vehicle, and register the transponder chip to the immobilizer. No tow to the dealer, no multi-day wait for a VIN-ordered key. Done on site, in your driveway or wherever the car is parked.
Do I have to tow the QX4 to the dealer if I have no working key?
How long does an all-keys-lost replacement take on a 1999 QX4?
My 1999 QX4 starts for a second then immediately stalls. Is that the key or something mechanical?
Can I program a spare transponder key to my 1999 QX4 myself at home?
