G20 Key Security, Generation by Generation

P10 (1st Gen Facelift)

1995-1998

You turn this key in the ignition like any other key, but there is a chip inside the head doing the real work. Your 1995 to 1998 G20 uses an ID46 transponder chip paired with Nissan's early NATS immobilizer system. No remote buttons on this one; it is a straight transponder key that the car reads every time you start it.

P11 (2nd Gen)

1999-2002

Infiniti upgraded to a remote head key with three buttons for lock, unlock, and trunk. It still uses the ID46 chip and NATS immobilizer, but now your key also handles remote keyless entry with a CR2025 battery inside. The FCC ID is NHV2VWB, and all keys must be registered together during programming, so bring every key you have when we show up.

What Key Does Your G20 Actually Use?

🔑

Transponder Key

1995-1998

A metal key with a thick plastic head that contains an ID46 transponder chip. No buttons, no battery. The chip communicates with your car's NATS immobilizer every time you start it.

🔑

Remote Head Key

1999-2002

Looks like a regular key but the head has three buttons for lock, unlock, and trunk. Inside is an ID46 transponder chip and a CR2025 battery that powers the remote functions.

Our Service vs. the Service Bay

Most Infiniti dealers in San Diego County stopped stocking G20 keys years ago. Marco still cuts them from code on the van bench because the older chassis is exactly what mobile is built for.

Problems We See on the Infiniti G20

🔑

NATS Immobilizer Failure

'Cranks, will not start, security light on' is bread and butter on any 1995-2002 G20 service. NATS stopped recognizing the ID46 chip after a weak battery or jump. Marco runs the Autel and re-registers in Imperial Beach or Escondido, no tow.

🪛

Key Blade Wear

Aftermarket blades wear faster than OEM, and once cuts are too shallow your ignition cannot read the pattern. That leads to no-starts or lockouts in an El Cajon parking lot. We cut a fresh blade from the original code, not from your worn key.

🔋

Remote Fob Battery Drain

The seals on the 1999 to 2002 remote head keys are not great. Moisture gets in, the CR2025 battery drains faster than it should, and lock and unlock buttons start working intermittently. We check the battery contacts and seal condition first. a new CR2025 and a clean of the contacts is all you need; the circuit board needs replacing.

Can You Program a G20 Key on Your Own?

P10 (1995-1998)

Yes - DIY Possible

You can program the remote functions yourself using the key cycle method with the trunk open. But this only pairs the remote signal. The ID46 transponder chip still needs professional programming with a locksmith tool.

P11 (1999-2002)

Yes - DIY Possible

The 1999 to 2002 G20 supports on-board remote programming. Insert and remove the key from the ignition six times within ten seconds until the hazards flash, then press a button on your new remote. This pairs the remote only. The transponder chip requires professional equipment to program.

Common Infiniti G20 Key Questions

Can I program a new remote for my 1999-2002 Infiniti G20 myself without going to the dealer? ▼

If you just need to pair a new remote, yes, you can do it yourself. Close all doors, insert and remove the key from the ignition at least six times within ten seconds until the hazard lights flash. Turn the key to ACC, then press any button on your new remote within five seconds. The hazards will flash again to confirm. But here is the catch: this only programs the remote buttons. If you have a brand new key blank, the ID46 transponder chip still needs professional programming. Call us at (619) 876-1271 and we can handle the transponder side on-site for $175 to $250.

What transponder chip does the Infiniti G20 use, and can it be cloned? ▼

Here is the honest answer: your G20 uses a Texas 4D-60 transponder chip (part number 692060), and it is technically cloneable. However, cloning requires specialized equipment and knowledge of the NATS immobilizer system. In most cases, we program a new blank key using the on-board method rather than cloning, because it is more reliable. We recommend genuine Infiniti blanks (NI02T) over generic alternatives. The cheap ones from Amazon can cause intermittent start issues that will drive you crazy.

My 1999-2002 G20 won't start even though I have a working key. Is this an immobilizer issue? ▼

It could be, and that is the first thing we check. Your G20's NATS immobilizer communicates with the Texas 4D-60 chip in your key every time you turn the ignition. If that chip is not synced correctly, or if the antenna ring around your ignition cylinder is corroded, the engine will not start even though the key looks perfectly fine. This is different from a dead battery or bad starter. We carry a transponder reader on every call and can verify the chip signal in minutes. If the immobilizer has locked out from multiple failed key attempts, we may need to do an EEPROM reset, which we handle on-site in Poway, San Diego, or wherever you are in the county.

I have a 1995-1998 G20 with a mechanical key. Can I add a remote to it? ▼

Yes, but with some caveats. Your 1995 to 1998 G20 did not come with factory remote keyless entry in the same way the later models did. You can install an aftermarket remote kit, but it is a separate system that gets wired into your door cylinders. It is more labor intensive and less reliable than the factory setup on the 1999 to 2002 models. If you want to go this route, call us at (619) 876-1271 and we can walk you through the options. We will be straight with you about whether it is worth the investment on your specific car.

💡

A Quick Note

Most San Diego G20 owners do not realize the chassis under their car is the Nissan P10/P11 Primera that Nissan never officially sold in the US. The NATS immobilizer Marco programs in your driveway in Lakeside is the same one Euro Primera owners deal with overseas. The parts cross-reference both ways, which is why the van always has the right blank.
