a few days ago my 04 G35 coupe 6MT's keyless entry started acting up. my remote would work one time and another it wouldnt, but then it got to the point where it wont work at all. so i changed the battery. didnt solve it so i thought my remote was bad but i tested it and it is sending the signal. any ideas?

 

i have the same problem..i just got my other remote and it started working again

 

I had a similar problem. I just purchased my car and the guy that delivered it said that the remote didn't work.

I went and purchased a battery installed it and seemed to work fine. For 6 minutes

Anyways the remote started to send bogus signals... locking the car when I put the battery back in. Then not working at all.

This is what I did and it's fixed the problem PERMANENTLY!

1. Take apart the remote as if you were to change the battery.
2. Remove the circuit board from the actual keypad and clean the copper contact points on the circuit board with an eraser.
3. Clean the rubber keypad and the plastic that goes inbetween the rubber and the circuit board in the same way with the eraser.

Give that a shot and let me know. Like I said since I've done it I haven't had an issue

 

i had to take it to the dealership to get the remote reprogramed now it works fine
