⭐ Built for the Infiniti G35 2005-2007, this 4-button smart key is a new genuine factory Infiniti unit of part number 285E3-AC70D, running at 315 MHz. Its buttons cover lock, unlock, trunk, panic. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. The same radio approval is fitted to 285E3-CB80D, so the part number, not the FCC ID, decides the order.

🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

This proximity smart key cannot be learned by hand. It is registered to the car through the OBD-II port with a diagnostic tool.

Compatible tools: the Nissan CONSULT dealer system, or a locksmith key programmer whose software lists this model and year.
Add key (spare): connect over OBD, read the BCM challenge and calculate the PIN, then register the new key together with every existing key the customer keeps, because registration erases all stored keys.
All keys lost: the BCM PIN is calculated from the challenge code first, then each key is registered in the same session.
Blade: cut the NSN14 emergency blade, sourced separately, to the vehicle's key code and test it in the driver's door.
Check coverage first: support depends on the tool's software version and the exact model year. Verify the Infiniti G35 2005-2007 smart key is in the tool's supported list before the job.

Frequently Asked Questions

Common questions about this product

The 285E3-AC70D smart key fits the Infiniti G35 2005-2007 with the 4-button layout, North American version. Match the part number printed on the back of the original key, and the button layout, before ordering. Keys for the same car can differ by trim, market and button count.
No. The FCC ID KBRTN001 is a radio approval that Infiniti also uses on 285E3-CB80D. Those keys can fit other cars or have other buttons, so the part number 285E3-AC70D on the original key is the deciding reference.
The 285E3-AC70D smart key transmits at 315 MHz. On this generation the transponder chip is not in the fob: it sits in the emergency insert key, which is not included with this listing. Match the frequency on the original fob too.
The Infiniti G35 2005-2007 smart key is programmed over the OBD-II port with the dealer system or a locksmith key programmer that covers this model. Registration needs the BCM PIN and erases every stored key, so register all keys in one session.
No. The 285E3-AC70D smart key is supplied as the key only, without its emergency insert blade; it takes an NSN14 profile blade. Source the blade separately and cut it to the vehicle's key code, by code or by decoding the door lock.
Yes. This listing is a genuine factory Infiniti 285E3-AC70D smart key, supplied new and unprogrammed, without the emergency blade. It is programmed to the car over OBD like any new key. Match the part number on the original first.
The 285E3-AC70D smart key runs on a CR2025 coin cell battery, fitted inside the housing. Replace it when the range drops or the dashboard shows a low key battery warning. If the battery is flat, hold the key against the start button to start the car.
