They don't work, stop working as of today, replaced the battery in one and no luck. Is there a fuse that could of went? any one else experience this?

 

There is a control box in the trunk located by the power antenna that could have failed. This control box receives the signal from the key fobs and relays it to the Body Control Module. Nissan calls it the "Multi-remote control unit (LCU05)".

Check a fuse under the hood, next to the battery. The cover calls it "ANTI THEFT" and it is towards the firewall end of the fuse block.

Try to re-program the key fobs. If the lights don't flash in step 3, it isn't going to work. Open the drivers door and then start over. Try this 2 or 3 times, it's a little tricky.

1. Unlock all doors and get in car.

2. Close and lock all doors with power door lock switch on driver's door.

3. Insert the igniton key and completely remove from the ignition switch
at least 6 times within 10 seconds. The hazard warning lamps (both turn
signals) will then flash twice and all previous codes will be cleared.

4. Turn ignition key to "ACC" position.

5. Push the "Lock" button on the new remote controller once. At this time,
the car learns the new ID code. The hazard warning lamps (both turn
signals) will then flash twice.

If you are programming just one remote, go to step 10.
If you need to activate additional remote controllers, continue with Step 6.

6. Manually unlock the driver's door only then lock again with door lock
****.

7. Push lock button on the additional remote controller once.

8. Hazard warning lamps (both turn signals) will then flash twice and
additional remote is programmed.

9. For additional remotes, go back to step 6.

10. When done, open the driver's door to exit programming state.


NOTE: A maximum of 4 remotes can be programmed to any ONE car.
