I have a 2003 G35 coupe that I just purchased last month and it came with only one transponder key and one FOB. and a wallet key. The driver door will not lock or unlock with the FOB or the door button. Can I program a new key or do I have to repair the door actuator first so I can lock the door to program the key and FOB.

 

To program the a new key, you'll have to go to a locksmith or a dealer. I'd recommend locksmith, it shouldn't cost more the about $50, if you buy the key yourself. As for your door lock actuator problem, search the website there is a DIY that may help you fix that problem. Programming additional FOB's can be done yourself. Its a simple process that is outlined on this site, in a DIY.

 

I'm having a similar problem. Only my drivers side door will not unlock with the key or the key fob. I have to turn and hold the key all the way to the right and roll the window down so I can reach inside the car to manually unlock the car. I haven't purchased this car yet. It came into the used car lot I work at. From what I understand the car is rare being a 2003 g35 coupe with 6 speed manual and the brembo package. Any advice or idea of what it will cost to repair? The other problem is the passenger window is acting weird. When I roll it up it goes all the way up and then rolls back down halfway.
