Is the FCC ID enough to pick the right key?

No. The FCC ID KR55WK48903 is a radio approval that Infiniti also uses on 285E3-JK62A, 285E3-JK61A, 285E3-JK600. Those keys can fit other cars or have other buttons, so the part number 285E3-JK65A on the original key is the deciding reference.

The 285E3-JK65A smart key transmits at 315 MHz and carries a HITAG 2, ID46 (PCF7952) transponder inside the housing. No separate chip is needed, but the key must be registered to the car with a diagnostic tool before it unlocks the doors or starts the engine.

The Infiniti G35, G37, G25, Q60 and Q40 2007-2015 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-JK65A key?

No. The 285E3-JK65A 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-JK65A key a genuine Infiniti part?

Yes. This listing is a genuine factory Infiniti 285E3-JK65A 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.

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-JK62A, 285E3-JK61A, 285E3-JK600, so match part number 285E3-JK65A on the original.

Not the 285E3-JL38A key - 433 MHz export 4-button key for the G35 / G37 / Q60 2008-2013 (marking 5WK49671); match 285E3-JK65A on the original.

Not the 285E3-AC70D key - a different part number; match 285E3-JK65A 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; source an 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 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, G37, G25, Q60 and Q40 2007-2015 smart key is in the tool's supported list before the job.
