Customer: No
JA: Are you fixing your Pathfinder yourself? What have you tried so far?
Customer: I would like to... I haven't done anything yet
JA: Anything else you want the mechanic to know before I connect you?

IF YOU CONFIRM

All "hands free" functions of the Intelligent Key (I-Key) do not work. For example, the doors will not lock or unlock when pressing either front door request switch.

NOTE:
^ The issue of all I-Key "hands free" functions not working may occur intermittently or all the time.

^ The message "No Key Detected" or similar may show on the Vehicle Information Display (located in the combination meter).

^ All I-Key remote button functions (door lock/unlock, etc.) WILL work normally when all I-Key "hands free" functions are NOT working.

ACTION

1.Inspect the I-Key's battery on its negative contact side.

If you do not mind me asking are you looking for the most possible causes and taking it to a repair shop or you are repairing it yourself and you need step by step instructions

The key fob works as it should. I don't think that's the problem. The alarm only goes off when I set it... Maybe every hour or so
