Which Nissan X-Trail does the 285E3-7LA6A smart key fit?

The 285E3-7LA6A smart key fits the Nissan X-Trail 2023-2024 with the 4-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 KR5TXPZ3 is a radio approval that Nissan also uses on 285E3-7LA6E, 285E3-7LA7A, 285E3-7LA7E. Those keys can fit other cars or have other buttons, so the part number 285E3-7LA6A on the original key is the deciding reference.

What frequency and transponder chip does the 285E3-7LA6A key use?

The 285E3-7LA6A smart key transmits at 433 MHz and carries a HITAG AES, ID 4A (NCF29A1M) 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 X-Trail 2023-2024 smart key programmed?

The Nissan X-Trail 2023-2024 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 285E3-7LA6A key?

No. The 285E3-7LA6A 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 285E3-7LA6A key a genuine Nissan part?

Yes. This listing is a genuine factory Nissan 285E3-7LA6A 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.

Can the 285E3-7LA6A key be added without the original key?

Yes. When every key is lost, the 285E3-7LA6A key can still be registered after the immobiliser PIN is read or calculated by the tool or supplied by the dealer. Check that your key programmer covers all keys lost on this model before the job.

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 285E3-7LA6E, 285E3-7LA7A, 285E3-7LA7E, so match part number 285E3-7LA6A on the original.

Not the 285E3-7LA7A key - 5-button key (remote start + hatch) on the same FCC ID for 2022+ Rogue / Pathfinder; match 285E3-7LA6A on the original.

Not the 285E3-6RA5A key - a different part number; match 285E3-7LA6A on the original.

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.

Genuine factory key - a new genuine Nissan unit, supplied unprogrammed.

🛠️ 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 Autel IM608, Autel APB131, Keydiy KD-X4.

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 X-Trail 2023-2024 smart key is in the tool's supported list before the job.
