Infiniti Key Fob Programming
Infiniti follows Nissan's rule. A remote-head key can be programmed at home by cycling the ignition, and a smart key can't. That covers 34 of the 103 Infiniti model years we list, on models like the G35, FX35, QX4 and QX56. The G37, the M-series and every Q and QX model we cover from 2014 on need a locksmith or dealer. Infiniti fobs take a CR2025 or CR2032, and the model pages show which by year.
Choose your Infiniti model for programming steps, the battery it uses, and the correct replacement fob with FCC ID and part number — 103 model years across 25 models.

What battery does an Infiniti key fob take?
Mostly the CR2025, which covers 55 of 103 model years. Infiniti also uses the CR2032, so check your model and year before you buy. A plain chip key has no battery at all.

Infiniti key types
The replacement keys we've matched to Infiniti models fall into 4 types. A model year can take more than one, which is why the model pages list each option with its FCC ID.
- Transponder Key 1999–2008
- A cut metal key with a chip in the head. No buttons.
- Remote 1999–2011
- A separate key fob that only handles locking and unlocking.
- Remote Head Key 2003–2009
- One piece: a cut metal blade with the lock/unlock buttons built into the head.
- Proximity Key 2003–2020
- Stays in your pocket — the car unlocks and starts without inserting a key.
