Spare Keys

[Wayne NZ]

Hi,

The key for the JDM 350GT Coupe are a transponder type and are coded to the cars main ECU.

There is an amplifier near the ignition switch which picks up a coded radio signal from the key. If the code matches the code in the ECU the engine will start.

You can demonstrate this by having a flat key cut and inserting it into the ignition switch. When you turn it the engine will turn over but not start as the ECU won't switch on the engine management system. If you then hold your real key by the switch and then turn the engine over it will start.

This is a very secure system but it does mean the keys are very expensive. You need to give the Nissan dealer your chassis number and model code from the plate in the engine bay and they can order the key for you. Nissan Japan holds the information on the key type.

You then get the key cut to match your original key and take all your keys and the car to the dealer and they will reprogram all the keys to work. If you don't take all the keys the key you didn't take will no longer work because reprogramming erases the previous codes.

If you only have one key do not lose it as the only way to get your car to go then will be to by a new ECU and keys.

My new key cost me $650 here in Auckland and the programming cost $50. It's a hell of a lot cheaper than an ECU so it is worth doing.

I would be very careful about buying keys from any other source as it could be expensive in the long run.

This security system is very similar to what Kawasaki uses for their imobilizer equipped motorcycles and it is very hard to defeat but expensive if all keys are lost.

Regards

Wayne

But how does the RED valet key work?...is there also a 'radio circuit' (minus the controls) of sorts in them too?

(Soz if this has already been answered)

same idea as the remote style key. both have transponder chips in them both are programmed to the car.

Thanx Chris.....so it's the same as the black keys....minus the magical buttons!

Thought that was the case...thanx buddy!

Spit.....still waving the CR banner.

I have experience in that side of it. my van runs the same setup. it was sold with two plain keys and I added a remote one to it,

no need to wave flags

I just work on these things...

cool, thanks man.

Can you believe that I've still got the original Jap battery in my car....I managed to find the date stamp!...(but could not read the CCA rating of this battery.)

(sorry for digressing, just thought you'd be interested in that!).....I managed to track down a 330CCA with correct power-pole postion and size, ..I reckon that will be ok for my v35...would you agree Chris?

Spit.....now waving the 'wave no-banners' banner.

[Chris Rogers]

that will be fine. thats what I use in them anyway.

[nissan rules]

2001 HV35 didnt have it. 2003 PV35 and CPV35 did have it.

Chris, for those who does not have the NATS, would Nissan still be the only means to get a spare remote (for door lock/unlock & boot, no key)?

Does that mean that the G35 remotes available on ebay motors could be usable in V35 that does not have NATS? .. like this ones

[Chris Rogers]

no. they are a different car TOTALLY. never assume that because it looks the same that it is internally- they are not.

[Chris Rogers]

to be honest I would look more at a GQ patrol key. I put a price up on one of those in the car audio section.

if you have a chassis number I'll look up a replacement key for you and give you the part number

[superspit]

I was waiting for you to say that mate!...a big noooooo!

[Chris Rogers]

to me its common sense they are different to everyone else for their market what makes you think they would sell a car that is the same as another market. hell the radios in these things differ widely from USDM -> JDM. (says he thats trying to crack the 2005+ versions..)

Can someone help me out to find the pin code? Living with only 1 set of key is very scary as you will always jump out from seat, thinking your key is still there..

[dannyw]

i know this thread is old.. but someone help me~~~

[johnr]

correct. I should really write a FAQ for all this stuff..

Hi,

I finally got my act together and got a spare key programmed for my 2004 V35 and it works fine. I purchased the key from Nissan spares using the chassis number ($141) had it cut ($20) and then had it programmed by the Nissan service dept at Gosford NSW ($30). I used the pin that I got from TomR33 and from Nissan Japan which were identical and the programming took 5 minutes. Quite an easy task.

I don't know if $141 was the standard price but I know locksmiths charge $110 - 130 for transponder keys but their programming instruments do not recognise Nissan keys. The email to nissan japan for the code is: [email protected] but TomR33 can also give it to you. Check the previous posts in this thread. Good luck
