Infiniti G35 key types & programming facts
2003–2006 Infiniti G35 models without push-button start use a transponder ignition key plus a separate keyless entry remote. Programming a new remote for these models can be done via an onboard procedure that cycles the key and uses the power door lock switch to enter learn mode, then pairs one or more remotes to the vehicle’s body control module. The transponder ignition portion generally requires proper immobilizer pairing, which many owners have done at a dealer or qualified locksmith.
Key types used on the G35:
- transponder chip key with separate keyless entry remote (standard metal blade ignition key plus 4‑button remote) (2003-2006 (non‑smart-key G35 models; USA/Canada))

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.
