Having a problem with the drive side door entry button from my 2005 Infiniti G35X sedan. Car has the smart key and for some reason the drive side button doesn't work to open or close the car.The weird thing is the passenger side works as will as the trunk button, both exterior button. I have both remotes, and both are working to start, unlock, lock, and trunk release the car using the remote buttons. I know the remotes battery are good because while stating the car the key light on the dash is green. Is there a fuse or did the button just gave up. Any help is much appreciated!
I am very sad b/c i got use to leaving my keys in my pocket and opening my car.

 

Either the button, or wireless remote inside the door handle has failed.

My car currently has this issue as well and exploring how to repair it. Need to pull off the door panel and have a look one of these days.

 

My idea on this would be to examine the wires which go from the body to the door through the hinge area (via the rubber boot). Think about how many times those get flexed or twisted over the years - every time you drive your car. Many of us experienced this problem with the trunk which has a harness that bends even further than the doors. It makes sense that eventually these wires could need repair.

Inspect that harness for frayed or broken wires. Could be the wire to the button or to the antenna... Hope that's what's happening.

 

thanks for the help i took of the door panel today and everything looks good. I didn't take of the second layer to see the door lock itself, but I definitely will take a look at the wires in between the door and the frame. I did remember that during the time it stop working the car did beep about 4-6 times, idk want it meant at the the time but the next thing i knew it stop working.

 

The key components are on the door handle. There is the actual button, and the remote sensor. If the button worked off and on and then failed all together, it's most likely the button. I'd test this by unplugging it and testing for continuity when the button is pressed. I'd then jump up the wires with the key nearby and see if it triggers an unlock command.

Replacing it is a different story. Still need to explore that.

I'm just waiting for a Sat when i have some time to pull my panel off and take a look. Getting annoying having to use my remote to unlock the doors now.

 

This is what you are looking at. This is the PASSENGER side handle, but the driver's would be the same, just mirrored.

#1 is the remote receiver that senses if the key is near the door.
#2 is the actual push button.



#1 is replaceable.
#2 looks like it can be replaced by removing the 2 screws, but it part of the harness, so the entire pigtail would need to change as well.

Don't know OEM part numbers for these compoents. I'm pretty sure in my case, #2 is bad due to me being able to sometimes get the door to unlock if i wiggled the button correctly.


Here's the FSM

Some wiring diagrams around page 118 might be useful here.

EDIT: I think the big issus is reaching the door handle to begin with. Not much in the door is open, but i beleive the wo outer screws can be removed allowing the handle to be pulled outwards to access the parts. This is coupe door, but I think this "shield" needs to be removed to access the guts of the door, with the window all the way up. Even then, the window might be in the way and needs to be removed first. A HUGE PITA which is why I haven't found much in terms of how to repair this issue. I bet many just let the button remain broken.



This is the only issue with my car right now...so I'd like to fix it. I actually purchased a driver's sedan handle off Ebay simply for the parts. When i receive it, i'll attempt the repair and provide my feedback. However, free time is at a premium these days, so it could be a few weeks.

 

update: Today i got both the remote and i just held down the drive side button, request button, and it started working. idk if its a feature that you can disable the button or maybe its broken. I've used it a few minutes ago and it seems to work normal. One possibility could be water corrosion due to the massive amount of rain that fell a few days ago. I really don't know what it could be, just happy.

 

That happened to mine as well. I could manage to get the button to work by pressing it down hard, or at different angles. Eventually it would register and work for a bit. The frequency of the times it wouldn't work however began to increase over time until it just stopped working all-together. I would imagine over time, moisture has corroded or damaged the contacts.

So hopefully it stays working for a while for you because replacing it looks like a HUGE pita. Mine worked intermittently for a year before it completely failed.


I did find some part numbers though. I don't think this is my issue, but might as well put some useful data on the forum

Remote sensors

Looks like it's 28587+A on their diagram. Unsure which OEM part number that is. I'd prob just stroll into a dealer and ask for these if they are about $40 each


Still hunting for the button which I think is my issue, but i ordered a used handle off ebay so i'll use that one (hopefully it works)

 

For 2006 coupe, I believe this is the part required to fix the failing button. It is integral to the handle, and has a pigtail that goes into the door where the handle pivots at the front. I have placed the order with Amayama.com; it is "pending approval." We will see if the order goes through. It's supposed to be my body color, too!

80640-CM45E - GRIP-OUTSIDE HANDLE

 

Here's the other direction I'm pursuing: replacement handles for FX35/45 series, of which there are many on Ebay. Much cheaper than the OEM full handle, and I'm pretty confident the handle can be taken apart to extract the button and pigtail and put it in the G35 handle. I see a lot of posts dreading disassembling the door panels to get to the handle, but it's the same sequence for replacing the window motor (which I have done and which people do all the time; it's not too bad). FSM has the step-by-step for removing the door handle. And I love the convenience of the button and I-key combo; it's worth the trouble for me.

Here's one example: https://www.ebay.com/itm/396911969277
