Which Nissan Patrol does the 285E3-1LB5B smart key fit?

The 285E3-1LB5B smart key fits the Nissan Patrol and Armada 2021-2024 with the 5-button layout. 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.

Is the FCC ID enough to pick the right key?

No. The FCC ID CWTWB1G744 is a radio approval that Nissan also uses on 285E3-1LB5A, 285E3-1LA5A. Those keys can fit other cars or have other buttons, so the part number 285E3-1LB5B on the original key is the deciding reference.

What frequency and transponder chip does the 285E3-1LB5B key use?

The 285E3-1LB5B smart key transmits at 433 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.

How is the Nissan Patrol 2021-2024 smart key programmed?

The Nissan Patrol and Armada 2021-2024 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 285E3-1LB5B key?

No. The 285E3-1LB5B 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 285E3-1LB5B key a genuine Nissan part?

Yes. This listing is a genuine factory Nissan 285E3-1LB5B 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 285E3-1LB5B smart key take?

The 285E3-1LB5B smart key runs on a CR2032 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.

🔢 PART NUMBERS

285E3-1LB5B part number

IMPORTANT - READ BEFORE ORDERING

BCM PIN and all keys in one session - Nissan 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 285E3-1LB5A, 285E3-1LA5A, so match part number 285E3-1LB5B on the original.

Not the 285E3-1LB5A key - Earlier 5-button Patrol / Armada key on the same FCC ID; trade sites list it for 2014-2023 Patrol and 2017-2024 Armada; match 285E3-1LB5B on the original.

Not the 285E3-1LK0E key - 3-button Armada S / SV key with no hatch and no remote start, 2021-2024; match 285E3-1LB5B on the original.

Buttons follow the car's options - remote start, parking assist and power door buttons only work on a car fitted with those options.

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 Nissan Patrol and Armada 2021-2024 smart key is in the tool's supported list before the job.
