I just installed a DD with seperate Nav in my 2005 G35 Sedan. Everything went well thanks to many of the posters here (except for the steering wheel control would not learn).

My problem now is this. My intelli key buttons work but the "keyless" start will not work unless I hold it within approx. 4". I can hear an audible "unlock" of the cylinder. Then it will turn. If it is farther than 4" it will not turn even though the "key light" is red (good). When I hold it next to the cylinder it turns green (bad) but does turn and start????

The battery is brand new in the key and even purchased and tested another 2025 battery(indicated in my owners manual not the 2032) and it was 100%. No go. It appears that the "indicator lights have reversed on me? Could the wires I tapped for the steering wheel control be causing a problem? I also have a hardwired video "solution" that couldn't cause a problem could it?

It seems like it is a "range problem" where it is supposed to sense the intellikey inside the car it doesn't sense it unless it is next to the cylinder.

Anyone have any ideas. I have NO MONEY now to go to the dealer (out of warranty also) Any help would be appreciated.

 

It could be that the little "antenna" in your I-Key got busted somehow.

No idea what your issue is with the tapped wires.

 

I only mentioned the "tapped" wires as wondering if it could have anything to do with the "range" of the I key. Just providing info in case someone knows something I could have screwed up with it.

I didn't have the I key around while installing the stereo, so I don't think it is "broken" in any way.

It really seems like what ever sends out the signal IN the car to encompass JUST the interior or recognize that the I key is inside is not working correctly somehow?

Of course the battery was disconnected for an extended period but worse case that just resets the computer.

The I key "works" in every way just that the ignition will not turn unless it is very close to the ignition. Very frustrating having to take it out to start the car.

Thank you very much for your response! Is there an "antenna" somewhere in the dash that I could have disconnected so it hurts the "range" of the broadcast?

 

btw, red means it can't read ur key... and green means it's reading it and therefore it starts... i don't see what's wrong with it

 

The problem is that it doesn't turn green unless I hold the I Key within 4" of the ignition. If it is any further away than 4" it stays red and will not turn. The key is supposed to work if it is inside the car anywhere. You shouldn't have to place it next to the ignition to start the car.

It worked fine prior to me installing the stereo so I am not sure why it doesn't work now as I do not know anything that would cause it, but seems related and seeing if someone could point me in the direction of what to look for.

 

sounds like the antena to your I-key is attenuated (or blocked) some how... i would disconnect each "new" wire you introduced with your custom setup until the key works like normal. also make sure the navi antena wire (if any) and/or radio antena wire is sheilded(no copper or gold wire is showing) or not wraped up with any of your ignition wires. That just my initial thoughts and what i would do.

 

to be more detailed i would let the I-key sit on the driver seat and disconnect the "new" wires of your custom setup that are tied to your ignition/steering wheel until my i-key is reconized again. this would isolate which wire or wires are causing the problem.

 

Yep since the steering wheel controls are not working anyways I was planning on doing that. I find it unusual that that would "block" it but is the only thing that makes sense. Very good information on the Nav wires and such, I did not know or think about that.

I need to hopefully solve this myself as I received only one I key with this car and upon checking Scottsdale Infiniti I was quoted a "programming fee" of $115.00!!! Which is the highest I have read on here. I am sure it isn't a "programming problem" and am sure you are on the right track, but if they charge $115 for that imagine what they will try and rip me off for to figure out the "blocking"??!!

I totaled my Lexus GS400 and purchased this car...and I love it. This board was instrumental in me making this purchase and my ability to save $350.00 by installing the stereo myself (everything but this "problem" is great) Thanks to all helping. I will do what kmckis1029 suggests in the next few days and post the results...but if anyone has "inside" knowledge on this feel free to let me know things to look for or do to fix the "blocking". I think this is the right track and again thanks to all helping!

 

it wouldnt reconize the key at all if it was a programming problem... good luck.. glad i could point you in the right direction at least.

 

OK..the steering wheel controller definitely had nothing to do with it.

The NAV wires?! That is definitely the problem somehow. I diconnected the "speed sensor wire" and the "reverse" wire at the dash and now the key works if it is in the cup holder, but not my pocket? I moved the disconnected wires around and that doesn't make a whole lot of difference...but not sure why it should make any difference if they are disconnected anyways?

OK I completely disconnected the Nav unit from the unit in the trunk and the HU...no better "reception"

I have a MAX685BT with the 980 Nav unit. I ran the Nav wires up the center console to the HU from the trunk.

Cutting the "speed sensor wire" from the Nav unit and the "reverse" wire from the HU got me a range of....gas pedal to bottom of steering wheel...the center console back to the cup holders over to passenger seat to door even with cup holders...the entire floorboard of passenger side.

I disconnected the entire nav unit form both sides all plugs and it made no difference.

I can leave the I key in the car even where I can actually turn the ignition and it does not beep at all for a warning either.

I added NO wires that did not come with the unit, so "shielding should not be a problem.

Anyone know where the car "broadcaster" is for the I key?

This is frustrating as the Nav wires seemed to have some kind of effect but taking it out of the equation completely did not "fix" it 100%.

I now only have the HU and a ipod in the glove box hooked up with slightly better "range" problems.

Going to leave my car torn apart for now hoping someone has an idea...

 

I have completely disconnected the radio. There were two white plugs that were plugged into the Bose radio that no longer hook to anything. Does anyone know if they have anything to do with the I key supplying power to the ignition or anything?

With the radio completely the range is still the same...just gas pedal toward passenger door back to cup holder. Any further back or towards drivers door the I key does not work. I have put new batteries in it to no avail.

I didn't even have the I Key in the car or on me when I installed it so I am sure it isn't damaged.

Is there anything that could have come unplugged somewhere. There is nothing in the radio hole except those two plugs I mentioned and I did not to anything around the steering wheel as my car is a 05 so it was not necessary.

I simply do not have the money to take this to Infiniti to "diagnose". It has to be something simple!

 

I would guess you may have accidently disconnected one of the internal antennae... Let me try to post a couple pics from the service manual... bear with me...

 

EXCELLENT! THANKS! I did mess with the center console to get the wires through there...to late for me right now to try it. But first thing tomorrow, I will.

I hope this is it, I think it makes sense that it could be...even if it isn't THANKS.

This is a great community, can't believe all the help I am getting!..

 

WOO HOO!...

I couldn't sleep and went out and found all of the antennas you posted......

It was the rear center console one. (unplugged...you had to pull it completely up and then look underneath halfway up towards the front for a SECOND plug!) The Nav wires apparently didn't have anything to do with it, probably just the fact the other antennae were more "open" because I had the dash apart.

THANKS FOR ALL WHO RESPONDED AND HELPED! Thanks Skyline for the eventual answer!

 

Excellent! A righteous repair!
This forum has bailed me out a bunch of times so it's nice to be able to pitch in.
