Which Nissan Murano does the 285E3-1AA7A smart key fit?

The 285E3-1AA7A smart key fits the Nissan Murano, Murano CrossCabriolet and 370Z 2009-2014 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.

Is the FCC ID enough to pick the right key?

No. The FCC ID KR55WK49622 is a radio approval that Nissan also uses on 285E3-1AA7B, 285E3-1ET5A, 285E3-1ET5D. Those keys can fit other cars or have other buttons, so the part number 285E3-1AA7A on the original key is the deciding reference.

What frequency and transponder chip does the 285E3-1AA7A key use?

The 285E3-1AA7A 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.

How is the Nissan Murano 2009-2014 smart key programmed?

The Nissan Murano, Murano CrossCabriolet and 370Z 2009-2014 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 285E3-1AA7A key?

Yes. The 285E3-1AA7A 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 285E3-1AA7A replacement a genuine Nissan part?

No. This is an aftermarket 3-button smart key built to replace Nissan part number 285E3-1AA7A on the Murano, Murano CrossCabriolet and 370Z 2009-2014. It uses the same frequency and transponder type as the original and is programmed over OBD with the same tools.

Which battery does the 285E3-1AA7A smart key take?

The 285E3-1AA7A 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

285E3-1AA7A part number

285E3-1AA0A related number

285E3-1AA5A related 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 285E3-1AA7B, 285E3-1ET5A, 285E3-1ET5D, so match part number 285E3-1AA7A on the original.

Not the 285E3-1AA7B key - Same Murano years and FCC ID but 4 buttons with the power liftgate button; match 285E3-1AA7A on the original.

Not the 285E3-1ET5A key - Later 370Z 3-button key (Z logo) on the same FCC ID; Nissan replaced 285E3-1ET5C with it; match 285E3-1AA7A on the original.

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

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; KR55WK49622 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 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 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 Murano, Murano CrossCabriolet and 370Z 2009-2014 smart key is in the tool's supported list before the job.
