These instructions apply to the Nissan Murano Mk3 (Z52) 2015-2020.

If the Intelligent Key battery in your Nissan Murano (Z52, 2015–2020) is flat, the remote will not unlock or start the car from a distance — but you can still start the engine. The immobiliser antenna sits behind the push-button ignition switch and reads the transponder inside the key by direct contact, so touching the key to the button lets you start normally.
First, Get Into the Car
A dead key will not work the remote lock. Slide out the mechanical key blade hidden in the Intelligent Key and use it to unlock the driver’s door. The alarm may sound briefly as you open the door with the blade; it stops once the system reads the key at the start button.
How to Start With a Dead Key
- Make sure the selector is in P (Park).
- Press and hold the brake pedal.
- Touch the back side of the Intelligent Key to the push-button ignition switch. The antenna behind the button reads the transponder in the key.
- When the key is recognised, the immobiliser clears and the start button is enabled.
- With the brake still pressed, press the push-button ignition switch — the engine starts.
After Starting
Replace the Intelligent Key battery as soon as you can — it takes a CR2032 coin cell (see the key-fob battery guide). If the engine will not start even with the key touched to the button and the brake pressed, the transponder in the key or the immobiliser itself needs attention.
Frequently Asked Questions
Why does the remote not work from a distance? A flat key battery only kills the remote radio functions. The transponder inside the key needs no battery — it still works by contact at the start button.
Do I press the button with the key or my thumb? Touch the key to the button first so it is recognised, then press the button as normal with the brake held down.
Nothing happens when I touch the key to the button? Move other keys or transponders away and try again with only this key. If there is still no response, the key transponder may be damaged.
Will the alarm keep sounding? It may sound briefly when you unlock with the blade, but it stops once the immobiliser reads your key at the start button.
