Intelligent key FOB dying out??
 

Hey guys, I've been having trouble locking/unlocking my g35 with the key FOB last week. I had to get really close to the car to lock/unlock it. This week, it completely stopped working. My initial thought was that the battery had died out. But the weird thing is that I can still lock/unlock my car by pressing the button on my door handle, and I can also still start my car without the key in the ignition. So I'm totally stumped. Any ideas?

i don't know if this is true for g35' but im pretty sure its the same mechanism. the beamer key usually lasts 6 months and they give you two to switch off.

it recharges itselfs within those 6 months

It recharges itself? That sounds a little far fetched. Where did you hear this from?

friend has a m6. those beamer people went over the WHOLE car before they sold it to him i was right there to drive his old car back

just googled it and there is an acutal battery in the infiniti g35 keyfobs :] sorry no recharging for you

Try putting the fob in your pocket. I know if I try and unlock the car with the fob too close to the door/trunk/etc it won't work. It needs to be at least a foot or so away from the car before it will allow you to unlock/lock the car using the button on the door.

I've tried that. I think the battery is dead. I just don't understand how it's still able to let me start the car without putting the actual key in the ignition.

most likely needs a new battery, they are 3 bucks. The i-key does not recharge itself. My i-key started acting up like yours recently and replacing the 2 year old battery fixed it. The signal transmitted for the unlock/lock/trunk/alarm buttons uses alot more battery power than the signal used to tell the i-key system you are near or inside the car, that may explain the problem you are having.

Get a new bttery, mine has never worked the same since I put a RF car starter in the G if you have one that could be the problem?

I will second what radioguy21 said about the different amount of battery power used. That sounds most logical. Aside from all that, go get a new battery when your key FOB still works. Save yourself some hassle in the future.

same problem here tryed to recharge it but nuthin change!

This is almost comical, just get a new battery and see what results you get. Mine is 5 years old and still works from a distance of 100 yards, it must recharge itself when I'm asleep....:biggthumpup:

^ hahahaha same thing happen to me but i changed the battery but it got a lil better

i thought the i-key light on the dash is supposed to warn you when your battery gets low, like blinks green or something.

Yea, that's right. The battery icon for the I-key does blink in the instrument panel when your I-Key battery is low. That's how I knew it was time to change it.

The keytransponder and the battery for the fob are seperate, that is why you can still start your car with a dead battery fob
