Infiniti G20 key types & programming facts
2000-2002 Infiniti G20 models use a conventional metal-blade ignition key with an embedded transponder chip plus a separate keyless-entry remote fob. Programming a replacement key typically requires cutting the blade to match the locks and registering the transponder and/or remote to the vehicle’s onboard keyless-entry system using an ignition/door-lock sequence. Many aftermarket vendors note that the keyless-entry portion can be programmed onboard by the vehicle owner, while immobilizer transponder programming may require specialized equipment or a locksmith.
Key types used on the G20:
- transponder chip key (standard metal blade with embedded chip) (2000-2002)

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.

Common questions
Does my 2000-2002 Infiniti G20 use a chip key?
Yes. Key suppliers list a transponder key blank (such as NI02T) for the 2002 Infiniti G20, indicating an embedded chip in the metal-blade key.
Can I program a replacement remote fob myself on a G20?
Yes. Keyless-entry remotes for 1999-2002 Infiniti G20 can be programmed using an onboard procedure involving repeated key insertion and door-lock operations.
Is the remote built into the key on a 2000-2002 G20?
No. Parts listings and battery-replacement guides show a separate keyless-entry remote fob and a standard metal-blade key, not a remote-head or flip key.
Can you program a G20 key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
