Hello. I am new here and hoping someone can help me. I have an 05 G35 coupe. Around Thanksgiving, my key fob stopped working while I was out of town on vacation. When I got home I tried the other one and it stopped working too. I read online that it was probably the battery in one of the fobs, so I replaced both and tried to reprogram the remotes. I could only get through the first step (key in and out 6 times, then lights flash) and could get no further with it. I finally gave up and went to the dealership. They could not reprogram my remotes either. They even tried to program brand new remotes to the car and they would not work either. THe only thing they could tell me is it was an Electrical problem and I would need to come back so they could play with it to figure out what the problem was. Has anyone has this problem before? Any suggestions as what to look for before I pay the dealership and arm and a leg to fix this?!?!? Thanks so much!

 

Hey did you figure out what the problem is? I'm having the same issue as you. It started after I had my windshield replaced, don't know if that has something to do with it. I also can't get past the reprogram step where the key is inserted 6 times and the hazards flash, once I put the key in and turn the ignition to ACC nothing happens.

 

I have not been able to figure this out. The dealership said they would need to hook the car up to a machine to figure out exactly what was wrong with it. Honestly did not feel like spending the money yet...I will definitely post if I ever do figure it out

 

This just happened to me this morning, both key fobs stopped working and I can't reprogram them.

Any ideas on the fix?

 

having issues

 

had same thing happen to me and the next day they just work fine and have since.. but now i have my hazards goin off for no reason.. im thinkin its my bcm and have to get a new one..

 

wow i have the same issue the remotes just wont program .. they just stop working. i replaced the battery in both. did the steps they just wont do it.. and im not goin to the dealer forget that. ill sale the car first. 2006, G35 coupe 6mt 58k miles mint... im goin to reset the cars ecm ecu by disconnecting the battery for 2weeks an see if it will wake up the remote programmer after i connect the battery back.. will let u know soon as i get back..

 

This just happened to me today. Both fobs won't work. Tried reprogramming and stlill nothing. Check fuses but windows and door locks work from inside car so I'm sure it's the fob.

 

In case anyone still read this old post.

Same thing happens to me when it rains hard or for a long time. (like a day).

Nothing works for a few days when the weather is warm but a little longer when cold.

My guess sometimes is getting wet and interfering with the signal. Not the remote signal, but the Communication signal in the car on the CAN lines.

This has happened to me again just a few days ago after the Sandy came by.
