I've seen a couple of questions here about the Nissan OEM remote locking as fitted to the Series 3 and later (Sept 93 onward as you can see here http://www.300zx.org.uk/model_variations.htm ).

 

1) Is there an alarm as well as central locking?

2) Does this OEM locking count as Cat 1 or 2 or anything Thatcham?

 

I've used the searchy thing but have only come up with a couple of guys asking the same type of questions!

TIA - Gio

i have a spare one of these which was for the nissan qx, they are like gold dust in the uk. on the qx it was a factory fit cat1 immobiliser/alarm. i will try and find the paperwork on it as it may be the same unit.

Ooh that's interesting. I found a US site which claims to sell them (and non-Nissan replacements) here http://www.keylessride.com/order/quote.asp?lbfix=yes&make=Nissan&remoteyear=1993&model=300ZX&frid=46999850 but they haven't replied to any emails yet...

yeah. original 4 button ones can be obtained from the usa. i sold my qx when i bought the zed but forgot to give the buyer the spare key & keyfob, hence why i still have it. lol. you do come across them on ebay regular, all usa ads.

How would you code a replacement to your cars system though?

Thanks, mario, I shall pop off and search ebay.

Does anyone know if it was a Cat 1 immob/alarm on the 300ZX like on the qx? (Series 3 ZX onward, obviously :D )

Graham, the site claims "PROGRAMMING

Price INCLUDES programming instructions for training the vehicle to recognize the remote." but I ain't tried it yet!

"....training the vehicle to recognize the remote."

Interesting.

 

Do you know what the receiver bits look like?

Supposed to be standard on series 4 cars (like mine), but how would I know?

programming is easy. i will try and find some pics out. does your ign key have a transponder in it ? on the qx it was a red bung at the side of where the metal key bit goes into the plastic. you also need the numbers off the back. will look something like this, need to match them up.

i have one of those keyfobs with mine , it doesnt do anything, presumably because i have an aftermarket UK alarm / imobiliser fitted.

 

i was under the impression that the Jap keyfobs used a frequency that wasn't legal in this country,

 

I think the reciever is under the wooden pannel in the passenger footwell

 

possibly (complete guess) this as it doesnt seem to be anything to do with my stereo:

 

That does look like a "keyless control assembly".

 

I'll have to look under me Zed's floorboards LOL.

Any Alarm System fitted outside the UK will NOT be recognised by Thatcham as an approved system as Thatcham Approval does not exist in Japan.

Alarm Companies (Toad,Clifford etc) have to pay thousands to get a system approved, once all the tests have been carried out it then goes on the approved list for insurance companies.

yes thats correct. 8yrs ago it cost £10k to have one model thatcham approved, thats why you dont see any crap cat1 alarms on the market.

It's given in the model comparison table http://www.300zx.org.uk/model_variations.htm

I've seen that too, somewhere, and will try to find the reference to post here.

I accept you're right, Bob. Would you be surprised to hear that out of 8 or so insurance companies I contacted, all except one are happy with this Nissan factory fit being Cat 1 and the other one thought it was only Cat 2?

 

In an ideal world, I'd like to keep the functionality of the OEM system (and the keyfob if poss) and just add something to make it Thatcham Cat 1. Is that possible?

In theory no you can`t upgrade it to Cat1 status, this is because the remote you have will probably be a fixed code rather than rolling code whice means everytime you press it you send the same code to the receiver making it easy to copy. Thatcham requires rolling code technology!

However, if you were to have a Cat2 Immobiliser fitted to the car you could then have fitted what we call a 2-1 upgrade such as the Toad 850T. This can be programmed to work of your original remote allowing you to keep it`s features.

If you don`t have a Cat2 fitted then you will need a full Cat1 system fitted none of which can use your existing remote.

 

Hope that helps!!

Hope that helps!!

Certainly does, mate, thanks.

Some last questions:

1. Can you fit a Cat 1 remote + receiver to the existing system?
   
2. Can you fit a Cat 1 thingy to the Z so it still does remote locking, boot lock and interior light?
   
3. Have you got any work planned down in London in the not-too-distant?

first one : not worth fitting to existing system.

 

second : yes you can.

Yep, you're absolutely right. Here's some quotes from a nice man at VOSA

The issue with Japanese remote locking systems surrounds the Radio Frequencies (RF) that they operate within. If a vehicle has a radio-activated immobiliser, alarm or central locking, only radio frequencies within the following ranges must be used in the UK:

 

417.90 - 418.10 MHz (until Jan 2008);

433.05 - 434.79 MHz; 868.00 - 868.60 MHz, 868.70 - 869.20 MHz and 869.70 - 870.00 MHz

 

Systems using other frequencies are unlawful. The maximum penalty for non-compliance is a fine of up to £5000 and/or 6 months imprisonment. In practical terms, you run the risk that you will not be able to arm or disarm the vehicle security system due to other signals on the same frequency interfering with your key-fob transmitter. If in doubt, you should check with the vehicle or security system manufacturer what frequency is used and replace the system if necessary. Type-approved devices are readily available as 'after-market' accessories. They will be marked to show they meet either European Directive 95/56/EEC or UN/ECE Regulation 97. Other systems might be acceptable: if in doubt, please check with the system manufacturer. We recommend replacement systems be fitted by a professional installer.

And as far as he can find out

I understand that the Japanese systems generally operate at 315 MHz, but I can't be sure.
