I had a digital keypad imobiliser in my old saxo.
it was a 98 reg.
It ahd all sorts of functions. Might be to complicated. as it controlled the ECU.
To much work!

Hi guys, sorry just got back from a nice long trip to thailand and off to uni in two days so dont have the imob ready but hope to take it to uni and
get some of the boffs to help me get over a couple of problems ive been having. Mainly due to suitable circuit damping, im worried about interference
when in a car. Im doing mechanical engineering so there should be a fair amount of people willing to help, also means i wont be able to do anything on
the car at the moment.
Cheers.

Find and OLD Mazda Rx 7 They have a simple imobiliers that works off of a key fob that attaches to the key ring. This just has to be present on the
keyring ... No touching it agains contacts etc.
Black box under dash and a aeiral up into column.
Couple of earths to sensors or door switches etc.
Whole system made by thatch I think.
Scot's do it better in Kilts.

got one on mine with the sensor on the tunnel , so i just put my keys in my pocket - sit in the car and the immobilser disarms. And it passed sva with
no ignition key.

Similar principle to the Rx7 one. Except I got mime for a fiver and not £50 but atleast you get the wiring diagram.

Do you need the offical bit of paper saying CAT 2 approved.
I thought they were only approved if fitted by a recognised installer not by DIY.

SVA just wants some form of anti theft device, it can be a concealed switch.
It came with the certificate in the box just needing to be filled out, and it was fitted as standard by the vehicle manufacturer, (not some blithering
idiot with a soldering iron and some sticky tape - oh hang on it was fitted by a blithering idiot , me!)

I have found a much less expensive and stealthier immobiliser that appears to be very effective. It uses a hidden magenetic reed switch and a magnet
as the key technology.
This was published December 1, 1998 in the AutoSpeed Magazine. (Aus)
Here's some text from that article:
quote:
If wiring up a couple of relays doesn't worry you and you can handle a soldering iron and a multimeter, this immobiliser is for you.
You only need a:
-12 volt heavy duty car relay;
-12 volt Double Pole Double Throw (DPDT) relay;
-12 volt flashing LED;
-reed switch that closes when a magnet is nearby;
-pushbutton that opens when pushed;
-broken remote from a car alarm;
-and a magnet.
Most of these bits and pieces you can get from an electronics shop.
Like all immobilisers, this one shuts down the car's EFI or ignition system. But what's different about ours is that if the thief steals
your keys (with the remote control attached), he still can't drive away with your car. That makes it just about unique!
So how does it work?
The guts of the remote transmitter case are removed and the magnet is placed inside. The circular magnet from a tiny speaker has been used here. When
you enter the car, you casually swipe the transmitter case past a special place within the car's cabin. This place might be on the centre
console, a part of the dashboard - pretty well anywhere. Hidden behind the area that you swipe is the reed switch - a switch that is sensitive to
magnetic fields. The swiping triggers the reed switch that in turn switches off the immobiliser.
Because the reed switch is located behind the plastic of the dash or centre console, there's nothing to see. The swiping movement can be quite
natural - part of your hand movement as you put on your seatbelt or settle yourself in the seat. That means that even if a potential thief is watching
you closely, he doesn't get any clues.The remote (at right) triggers the reed switch (left) whenever it comes close. Only you know the location
of the reed switch!
When you want to arm the immobiliser, you press the button. The pushbutton can be in complete view - the thief gains nothing by ripping it out and
either disconnecting the wires or bridging them. When you press the button, the on-dash LED starts to flash, indicating the car is now immobilised. It
also reminds you to switch off the system when you re-enter the car.

Just made one of the relay type/ reed switch immoblisers. Superb!!! easy to make and works a treat! if i think on i will put on a copy of the wireing
diagaram and my own which makes things even easier... even i understood it and i HATE electrics!!! cant take the credit, mate in the pup drew it!!!
well worth the £15 or so that i cost to make, and thats with all new bits!
take it easy,
rob
