u can get an old fashion key and hav it cut to hide under the car to use in doors ONLY... do not put it in ign lock... try a good locksmith they usually can program NISSAN/INFINITI keys ... or if lock smith cant program key have them cut it and go to dealer and have them program all ur keys together.. tell'm the key just stopped working its an extra one i dont use often...

 

hmm got a question, so any nissan key with a transponder will work on the G35?
Altima , 350z , GTR , Maxima key etc?

 

Go to a Nissan Dealer its cheaper.

 

Check the catalog I posted. The key we have is the NI04T. It's used on a lot of Nissans by '06.

 

The locksmith I dealt with seemed very knowledgeable. I'd caution against buying just any random transponder key. He told me that the keys changed from model year to model year and sometimes even during a single model year. Most locksmiths do not have the programmer needed to enroll new keys. Do your homework and check around before you end up wasting your time.
