Which Nissan Armada does the 285E3-1LB5A smart key fit?

The 285E3-1LB5A smart key fits the Nissan Armada and Patrol 2014-2024 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 285E3-1LA5A, 285E3-1LB5B. Those keys can fit other cars or have other buttons, so the part number 285E3-1LB5A on the original key is the deciding reference.

What frequency and transponder chip does the 285E3-1LB5A key use?

The 285E3-1LB5A 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 Armada 2014-2024 smart key programmed?

The Nissan Armada and Patrol 2014-2024 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 285E3-1LB5A key?

Yes. The 285E3-1LB5A smart key ships with its emergency insert blade, NSN14 profile. The blade has to be cut to the vehicle's key code, by code or by decoding the door lock, before it opens the driver's door when the key battery is flat.

Is the 285E3-1LB5A replacement a genuine Nissan part?

No. This is an aftermarket 5-button smart key built to replace Nissan part number 285E3-1LB5A on the Armada and Patrol 2014-2024. It uses the same frequency and transponder type as the original and is programmed over OBD with the same tools.

Which battery does the 285E3-1LB5A smart key take?

The 285E3-1LB5A 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

285E3-1LB5A 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 285E3-1LA5A, 285E3-1LB5B, so match part number 285E3-1LB5A on the original.

Not the 285E3-1LA5A key - a different part number; match 285E3-1LB5A 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 needs cutting - the emergency blade is cut to the vehicle's key code after the key is programmed.

Aftermarket key - not a Nissan factory key; CWTWB1G744 is the FCC ID of the original key it replaces.

🛠️ 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 Launch X431 Immo, Autel IM608.

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 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 Armada and Patrol 2014-2024 smart key is in the tool's supported list before the job.
