not quite, if the remote dies and you cannot get it working again you are screwed..

that is why I prefer full alarms.

Silly question perhaps - I thought most (if not all?) alarms have overrides on them? As long as you have the key and can remember the generally obscure combination of buttons and actions (and recite an ancient latin text when the moon is blue etc etc... :) ) then you can at least get the car going until the remote is sorted out?

full alarm is easier to 'fix' when you destroy a remote key. the other way involves a trip to a dealer or in this case a email to japan to get a new key.

if you have two OE keys then upgrade is fine.

upgrades RELY on the OE remote key working. with out it no go.

Can anyone summarise for me, I am still a bit perplexed.

Can you have the car opening/disarming and starting using the original key fob only, or can you use an aftermarket system instead?

I would prefer to keep the original stuff locked away and use something that can easily be replaced... can you make them both work?

As for only one key, that is a killer, I need a spare ready to go, just in case!!

in summary:

OE key can be used to control an upgrade alarm

if the alarm used has a fob then the OE key must still be used to start the car.

the OE key has a transponder inside it that controls the NATS system. no OE key = no go. had a call on that today - fellow lost his keys and wanted to start his car with a blank copy - nup!

make more sense now?

Controller Area Network- ln laymans terms - take concept of the internet and squash it into your car. everything talks to everything else via a computer command. break the link and it all comes to a grinding halt..

Don't even f**king start me on CAN bus f**kups.

I've got an Autowatch 446Prem (with integrated turbo timer) on my Z33 and, coming off the Brant, its a great piece of kit. Since I don't have my OEM fobs anymore I got Autowatch ones. I'm pretty sure the installer says they can integrate with the factory items (he also fits alarms onto V35s for compliancing).

Cheers Chris, so the OE Key has the door lock buttons on it, or are they seperate?

The OE Key is just a Key with a 'chip' in it that makes sures all the binary codes line up for the Starter to earth at the right time...

Simplistic of course, just like me...

no they are on it. exception is the red valet key.

your assumption is correct.

Cheers Chris!

So to completely clarify, the simplistic approach

  1. Is there an Aussie Key (Presume Nissan) that can be made to do all of the Standard Jap key functions, including open doors, engine start, open boot etc?
  2. What brand and model of Alarm can replace the Standard 'remote' functions listed above, along with the usual Alarm/Immobiliser functions?
  3. Do I have to have 2 black boxes on my Keyring (1 built in to the Key and 1 for the Alarm Remote of your choice)?
  4. Can I just have a basic key (Aussie Nissan with inbuilt transponder) and an alarm remote with boot release (depending on actuator installed on car)?

The reason I ask is, as a 'simple' man the only items on my Vehicles Key ring are a black box (alarm disable & central locking), Ignition Key (copied) to start car and a Siren silence key for hidden siren. Car will still not start tho.

I can't cope with heaps of stuff dangling from ignition or filling the pocket.

    • Me, I would happly spend some more coin on better tyres for my street car  Will they work, yes, of course, but why substitute some dry grip/braking distance, and wet weather grip/braking distance on what is really old tech to save some coin on your "precious" street car In the end it might not be you that farks up, it's the thousands of other idiots on the street that you need to worry about  For a street car that gets some "fun time", I have found that a quality tyre that can handle dry, wet, cold (Canberra gets pretty cold) and hot conditions, which may costs a little more, is great insurance  From my experience with them (driving around Goulburn in the winter) the RE003's are pretty poor in cold and/or wet conditions on the street If RS4's didn't hate gripping in the cold I would be running them always on the street,  great in the dry, OK in the wet, but, they do hate the cold, with a passion, I run PS5's year round now, basically, I've found the PS5 to be a great year round street tyre for all conditions, they last well, and are mid range pricing wise TL;DR. Tyre choice is probably like what brand and grade oil you should use, ask 10 people, and get 10 different answers... LOL
    • Extend the sensor out of the car, put it in a pot of oil, heat oil up. You'll get to 80-120 then 馃槢
    • Yeah - I tried throwing the formulas from ChatGPT and it tried it's best as it told me that the Formula in HPTuners as requested is a Linear function, but the original data I provided it (resistance to temp) is not linear and thus it kept trying to suggest formulas that would be more accurate in regions I actually want it to be accurate in. But I didn't quite understand it at the time. I have now thrown the data into graphs and can clearly see they're all different shapes. Given it's an oil temp sensor I probably want it to be most accurate between 80 and 120c - So I don't really see much alternative other than driving the hell out of the car and letting it cool down from 120C, noting the voltage on the sensor as it chills out. But at that point if I write it down, well, I'll be able to know this from the voltage. Would look pretty stupid on a datalog or a video showing me going down the straight at 0.265V Oil temp 
    • Yeah, it looks like it's being ran as a constant current setup is my guess. Get some more data points, reading the degrees C on the gauge, and what the voltage is you're seeing out of it. The sensor itself is not linear, even in smaller ranges of like 20 - 60 it's non linear. But if we can get some good plots, particularly at those 5volt steps, it will be very easy to work out, and then I can give you a logarithmic formula if its you need an actual formula. Also, very likely ChatGPT will lead you astray with some of this stuff, as it totally depends on how the circuit is built.
    • So to further complicate things or hopefully explain better: This is a VDO sensor. It clearly does this math inside the gauge itself... because it displays a temperature in C to me instead of a voltage. The signal wire to the gauge is in Volts, not Ohms. I have just teed into this and sent it to the ECU.
