Program Keys and Remote Controls

The Nissan Murano Z50 (2004–2008) allows you to program up to four remote controls. If a remote stops working after a battery change, or you add a spare, it can be reprogrammed without a diagnostic tool. This guide explains how to enter programming mode, sync your remote keys, and replace the button cell battery.

Before You Start

• Maximum of 4 remotes can be stored.
• Any remote not programmed during the sequence will be erased from memory.
• Ensure the vehicle battery is fully charged.
• Check that all doors unlock and locks operate smoothly.

Programming the Remote

1. Insert the key and turn the ignition from position 0 → 2, six times within 10 seconds.
2. Turn the ignition OFF, but leave the key inserted.
3. Wait for 2 seconds — the hazard lights will flash twice, confirming programming mode.
4. On the remote, press and hold the unlock button.
5. While holding unlock, press the lock button three times.
6. Release the unlock button — the indicators will flash once, confirming the remote is stored.
7. Repeat steps 4–6 for each additional remote (up to 4 total).
8. If 4 remotes are programmed, the indicators flash three times to show the memory is full.
9. Switch the ignition ON, then OFF, and remove the key to exit programming mode.
10. Test each remote to confirm lock/unlock operation.

Replacing the Remote Battery

1. Remove the small screw securing the fob casing.
2. Carefully separate the case with a small screwdriver.
3. Do not touch the printed circuit board.
4. Replace the button cell with a CR2032 3V battery.
5. Reassemble the case and refit the screw.
6. Test the remote to ensure proper function.

Troubleshooting & Tips

• If a remote does not program, repeat the procedure from the beginning.
• Replace the fob battery if the LED or signal is weak before attempting programming.
• Always program all remotes in the same session — unprogrammed ones will stop working.
• If programming fails repeatedly, the Body Control Module (BCM) may require inspection.
