Which Infiniti FX35 does the 285E3-CL02D smart key fit?

The 285E3-CL02D smart key fits the Infiniti FX35 and FX45 2004-2008 with the 3-button layout, North American version. Match the part number printed on the back of the original key, and the button layout, before ordering. A key with a different part number may not register.

Is the FCC ID enough to pick the right key?

No. The FCC ID CWTWBU619 is a radio approval that Infiniti also uses on 285E3-CL01D. Those keys can fit other cars or have other buttons, so the part number 285E3-CL02D on the original key is the deciding reference.

What frequency and transponder chip does the 285E3-CL02D key use?

The 285E3-CL02D smart key transmits at 315 MHz. Its ID46 transponder sits in the emergency blade, which is not part of this listing, so source a chipped NSN14 blade. The key is then registered with a diagnostic tool before it starts the engine.

How is the Infiniti FX35 2004-2008 smart key programmed?

The Infiniti FX35 and FX45 2004-2008 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.

Is the emergency blade included with the 285E3-CL02D key?

No. The 285E3-CL02D 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.

Is this 285E3-CL02D key a genuine Infiniti part?

Yes. This listing is a genuine factory Infiniti 285E3-CL02D smart key, supplied used, previously fitted to a vehicle, without the emergency blade. Check that your tool can register a used key on this platform before the job. Match the part number on the original first.

Which battery does the 285E3-CL02D smart key take?

The 285E3-CL02D 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.

IMPORTANT - READ BEFORE ORDERING

BCM PIN and all keys in one session - Infiniti Intelligent Key registration needs the BCM PIN, calculated from the challenge code the tool reads, and it erases every stored key, so all of the customer's keys must be registered in the same session.

FCC ID is not enough - the same approval number is used on 285E3-CL01D, so match part number 285E3-CL02D on the original.

Not the 285E3-CG025 key - a different part number; match 285E3-CL02D on the original.

Not the 285E3-1BA7A key - a different part number; match 285E3-CL02D on the original.

Market version - this key is the North American version; check the part number on the original before ordering.

Blade not included - this key is supplied without its emergency insert blade, which holds the ID46 transponder; source a chipped NSN14 blade and cut it to the vehicle's key code.

Used genuine key - this key was previously fitted to a vehicle; check your tool can register a used key on this platform before the job.

🛠️ 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 locksmith tools whose software lists this model, such as Abrites AVDI.

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 FX35 and FX45 2004-2008 smart key is in the tool's supported list before the job.
