Key Fob will only start the car when inserted into the slot. The door button to unlock the car does not work, need key to open the door.
Key Fob has new battery and Flipper Zero sees the signal.

Thank you

 

None of the iKey buttons work?
The simplest answer is the battery in the FOB - are you sure the current battery good and it's not in upside-down? (Easy mistake which I have made).
Option 2 is that your car has somehow forgotten the "registration" for your iKey. I don't know the steps to reregister a key but a locksmith or Infiniti shop could help there.
Possibility #3 is that there's something wrong with the 'Remote Key Entry Receiver" or the fuse which relates to that. Is everything else on the car working as expected?
And finally, check to be sure you haven't taken on water in the area of the passenger footwell. The BCM and Remote Key unit are there behind the glovebox and they don't like to get wet.

Good luck. Let us know what you find.

 

Update. The key worked this morning. But when started the car the radio/AC would not come on/work. The carpet is wet so thinking the BCM got wet. I just got the car as well. Sunroof draining issue possible. Might need a new BCM.

 

Not necessarily. Given the sporadic behaviour it seems you may have caught this in time though there are no guarantees. Many have had luck removing the BCM and letting it thoroughly "dry out." Also ensuring the connector pins/ terminals (both on the BCM and the individual connectors) are clean, dry, and free from corrosion upon reassembly.

I would suggest- aside from how you intend to address the sunroof drain issue- disconnect the battery, remove the BCM, and see how things look and go from there. The electrics on these cars are very tough so don't assume the worst off the bat. Good luck.

 

Water all over wires and inside BCM.

 

At least now you know the culprit. I'd still give the board(s) a thorough cleaning and go from there as this would preserve your RKE/IVIS codes. Keep in mind that any replacement will require programming- typically any qualified locksmith should be able to do this easy enough.

Also, while searching for potential online repair options for my flickering gauge cluster, there are also online services that can "repair" damaged BCM's though I have no experience directly with same.

Plz keep us updated.
