I thought I did in my post ;-)

Here it is in specific steps-

Disconnect Battery - leave for 30 seconds
Reconnect Battery
Wait a couple of minutes
Enter vehicle
Take key fob that is not working and TOUCH against "Start" button - approx 10 seconds

Try key fob to check it relearned itself

Thx for the heads up! I was going to do the reset. With a scanner from a buddy of mine, but didn’t not have the current update. I did the Battery disconnect and both fobs work great now!

Omg, had the same issue with my murano 2018??‍♂
Tried all of the steps above and it didn’t help.
Shame to me, I did install key fob battery incorrectly. Make sure that + facing to the bottom. Now everything is working.

Key problem resolved.



After searching the internet for my Intelligent key problem that had stopped working here is the answer that worked.
Remove key from the back of key fob, press start button twice inside of car but be sure not to start the vehicle. Next get out of car and close the door, insert metal key into drivers side key slot on door handle and turn key to lock and unlock position once. Go back into car and shut off ignition by pressing start button once, ignition is now off. Problem fixed, this worked for me which saved me time and effort running back to the dealer. Note this may have to be done again when changing a dead key fob battery, not to mention it might just save someone about a $100 .00 or more.
Wow thank you that actually worked. I was about to go yell at the dealer. Lol. I changed the battery in the remote. Sat in the car , pushed start twice with a couple seconds in between. Got out and closed the door..stuck the key in from the back of the remote and turned it left and right...got back in and turned the car off and closed the door and it worked. I know I'm quoting what you said pretty much but someone wanted verification. Thank you again!

THIS WORKED FOR MY 2016 NISSAN ALTIMA!!! Thank you so much for posting this! My spare fob wouldn't turn the car on but I could lock/unlock. So weird! You just saved me money and not needing to call off from work. THANK YOU! And yes, I did it twice and it worked!!!

There are two separate Nissan KeyFob issues that I have encountered.

Issue #1 : After replacing the keyfob battery you still get invalid key ID or no Key detected messages. Door request buttons also no longer work. Keyfob buttons to remotely open doors, etc typically still work. You can start the car by pressing the start button with the keyfob itself. (or by inserting it into the keyfob emergency start receptacle on some models)
Solution: Remove the backup door key from the keyfob. Enter the car and leave the keyfob inside. Press the start button twice (to cycle from OFF to ACC to ON). DO NOT Press the brake! Now exit the car leaving the Keyfob inside, but take the backup door key with you. Close the door and insert the backup door key into the door lock. Turn to the left to lock the drivers door. You'll hear the locking mechanism. Now turn the key to the right to unlock the door. Again, you'll hear the unlocking mechanism. You can now remove the door key and reenter the car. Push the start button one more time (don't touch the brake) to turn it to the OFF mode. The Invalid key ID messages should now be gone and everything functioning normally.

Issue #2 : This problem is basically the opposite of the above. Everything works normally except that none of the push button functions of the keyfob will work. Remote door lock, panic button, remote trunk release and remote start (if so equipped) do not function.
Solution: The ECU (main computer) must be rebooted with the keyfob inside the car. During a cold boot of the ECU the push button functions of the keyfob are re-programmed if it is inside the car. The easiest way to accomplish the cold reboot is to disconnect the main battery under the hood for a minute or two and then reconnect it. Be aware that disconnecting the main battery will erase the learned settings from the ECU, so the car may idle a little differently for the first few miles of driving. It will quickly return to normal.

If the battery is replaced in the keyfob before you start having intermittent problems, you typically won't have to do either procedure described above. However, if the voltage gets very low on the battery in your keyfob, the internal memory can become corrupted and replacing the battery alone may not bring it back to correct operation.

Finally: It has been reported that both keyfobs can be reprogrammed at once for either issue by leaving them both inside the car while performing either procedure described above. I've never had to do more than one keyfob at a time so I can't verify that, but it sounds like it should work.

Footnote: The correct replacement button cell battery is a CR2032, however a CR2025 will work in a pinch. The only difference is that the CR2025 is slightly thinner (2.5 vs. 3.2 mm thick) and has a slightly lower capacity so it won't last quite as long.
Big thanks to all memebers for help. It works and save me lots time and money.

Thank you

Remote control problem REALLY resolved



As mentioned in the previous message, this procedure did NOT work for me with the problem described.

The solution turns out to be very simple. Although there may be some other secret way to get the car to reprogram the remote control functionality, the brute force method that works is to simply do a cold reset of the ECU. The easy way to do this is to simply disconnect a battery terminal - wait several minutes - and then reconnect it again. Before reconnecting the battery again, make sure the keyfob is inside the car. The ECU apparently only attempts to reprogram the remote functions on a cold boot and if the key fob is not within range, it won't work.

Both of my remotes were dead and I did this on each one - one at a time. You might be able to do more than one at once, but I guessed it might be necessary to do one at a time.

Please note this only works to solve the problem of the keyfob remote buttons not working. I believe this is most likely to happen after changing the battery in the keyfob. If your door request buttons are not working, or you are getting other errors or problems when attempting to start the car, this will probably not help.
This worked great on my 2013 Pathfinder - Thanks for the help.

I had to join just so I could share my very easy overlooked fix. I did both of the techniques described and neither worked for me. Great, all I could think of was the $500 bucks for a new key fob. Then I read somewhere that the first place to start was to change the battery, well duh of course, I have done that and still I get the message that says to change the battery and key fob not detected. BUT then I read that button cell batteries have an expiry date. What?? So I looked at the batteries that I had that were relatively new, but they had expired in April 2016! They were expired by 5 years! I bought a new battery, changed it and my remote worked flawlessly. So if you are like me and thought the batteries you had were ok, they may be expired. Mine were from Ikea and had the expiry printed on the back, if they don't show an expiry, I would not bother wasting your time with them. I hope someone else finds this helpful and saves them any more frustration. Good luck!
