One key and fob works and the 2nd set will not start the car or unlock the doors.

Now my question is if I reprogram the keys using the following instructions does that only reprogram the fob or will it acknowledge the use of the 2nd key?

I want to use my 2 sets of keys interchangebly

Here are the FOB instructions BTW:

To reprogram (enter new ID) key fob (keyless remote controller) follow the steps.

1. Close all doors and lock all doors

2. From the door switch unlock the trunk.

3. Insert and remove the key from the ignition key cylinder six times within 10 seconds.
NOTE:
Key should be withdrawn from ignition key cylinder completely each time.

NOTE:
Do not rush the insertion/removal key cycling process. The side
marker/tail/license lamps and interior illumination will flash twice when this step is
accurately completed.

NOTE:
At this time, the new ID code is entered and original (previous) ID codes are erase.

4. Manually unlock and lock the driver side door

5. Push any button on the new remote controller once.

If there is only one remote controller skip step 6.

6. Additional ID code entry
Repeat step 4 and 5

7. END.

NOTE:
If you need to activate more than two additional new remote controllers, repeat
the procedure on step 6 "Additional ID code entry" for each new remote controller.

NOTE:
Entry of maximum four ID codes is allowed and any attempt to enter more will be ignore.



Thanks!!

 

Anhhh nevermind

How do I program a new ignition key with chip?
Unfortunately, this can only be done at the dealer. To program the key it is necessary to have an Infiniti Computer, a special program and password.

 

Sounds like they gave you the wrong set of keys.

 

Hey there, where'd you get those instructions? I did a little poking, because it seems like those are valid-ish instructions, just not for a G35. They seem to be from an earlier model car, like a G20.

I'm calling the dealer when they open

 

Infiniti help.com, lots of good info.

Well I know the instructions work because I have programmed 2 FOBS. I just cannot ever get the car to start with the 2nd key. I am thinking that if cru is right then hopefully they can just reprogram my key to start my car.
