I think you nailed it
 

That sounds like a good answer to me

:iagree:...Corvettes have a similar set-up/fob slot

Thanks! Now that is a more constructive answer! Geeze 2 pgs of smart *** replies just to get an answer to a real question.

Welcome to the internet!! :tup:

Lol

Love it!

Did you guys know our fobs work with no battery? I know, wtf is this guy talking about, right? But I've tried it. I've removed the battery, gotten in my car with dead fob in pocket. Car starts right up.

As said earlier, its most likely using an RFID chip so the Z can just scan for that. The battery is mainly for the remote functions i believe (lock/unlock/panic).

Right, that's exactly what's happening. So here's what I can't figure out -- why do we need a fobgina at all then? What am I missing here?

Yep - that's the beauty of passive RFID.

The principle operation of the FOB inside the keyhole is the same as RFID tags. The keyhole powers the FOB if it has no battery.

But why do you need to power the fob at all? You don't need to power it to start the car. It's passive RFID, and you can start your car -- fob in pocket -- even with the battery completely removed. The only thing the fob needs power for is for the lock/unlock/horn buttons to work, and to be able to lock/unlock the doors by just pressing the button on the outside of the door. Well, you're not going to be using the buttons on the fob while it's in the fobgina for obvious reasons. And there's no reason to get out of the car while the fob is in the fobgina to hit the external door lock button. I just don't see the functional value of the fobgina. It's not like it recharges a dead battery or something.

maybe its in there because as guys, we inherently like to stick stuff in holes.

im just happy that we have the ability to leave the keys in our pocket and we aren't required to use the fobgina (like in bmws). the nissan keyless entry system works better IMO than some of the others. my friend's camaro has remote start but when you get in the car, you still have to insert the key and turn. what sense does that make? the only good thing that does is allow you to turn on the AC before getting to your car. if the biggest issue of the nissan system is a fobgina that may not serve any purpose, im ok with that.

:iagree: Now that's the most intelligent answer of this entire thread so far! :bowrofl:

so none of you got the button battery replacement warranty? it only cost me $3,500. Now whenever my fob battery runs out i get a new one FREE. i dont care what you guys say. $3,500 for free button batteries for as long as i own the car.... SICK DEAL :p
