Imobliser
Hi,
I have looked at the previous thread on imoblisers. i fancy the idea of a key pad imobliser, i have tried maplins for a system, to get the reply of
hey, what you talking about??! have tried a few places but no good. I know sod all about electrics, fitting my new loom is about my limit! so any
ideas?? any one done it and fancy making another?? obvisouly for cash!!!! what else have pepole done, dont realy want a battery isolator/ race style
cut off switch. How about a switch in the low tension side of the ignition? i know that this works as ive done it before on my mini`s (God knows why
any one would want to nick a mini!!) but what does the nice SVA inspector think??... find the switch, moblise car and drive off!! theres only so many
places that you can hide a switch in a locost!!!
Cheers for your ideas....
Rob

Hows this for an idea, I've seen this before, very simple, but very effective. If you can get a wire from the (-) of your coil and somehow hide
it(run it under the coil?).run this wire to say a toggle switch and to earth. If the (-) on the coil, runs to earth, theres no way of starting it.
Providing you can hide the wire and the switch!

i put a switch in the lt ignition wiring it is mounted next to the steering top mount and when off lays against the mounting,i cant find it and i
fitted it also an isolator switch is a good idea bridged with an in line fuse to keep parking lights etc on

Keypad imob...
hey bob how much would you be willing to pay for such an item???id only ask for cost of materials cause itd be quite interesting to do for myself
cheers

Cost of materials sounds good to me!! and P+P! i wouldnt have a clue how much something like that would cost??!!! do you? couldnt realy say how much i
would pay...you name the price and i will say yes or no!!
I guess that you know a bit about electrics??? I know nothin about electrics.... i was thinking of somethin that would self activate when the ignition
is turned off, isolating the LT side of the electrics, either making an earth or isolating the live to the coil?? also when activated possabily turn
on a flashing LED?? I guess that this will also require a constant live?? what would happen if the Battery was disconected then reconected would this
overried the key pad or bugger the system up so that even with the code you cant start the dam thing???? Possable??or am i just thinking of the
impossable!!!??
Cheers
Bob

well i cant confess to being an expert but i know enough to get me through. let me just ponder this for a day or two, get some costings and ill try
and get get back to you. (As macca knows thats not as easy as it sounds.)

are you looking for the code to be programable. so you can change it when you want. if this is so then if a teef disconects battery to try to disable
it, the code will revert to the original number.this is using a PIC microcontroller. is a programmable circuit a must have and if yes do you need it
to retain your personal no'??

I know for a fact that RING done keypad imobilisers about 9 years ago because i have one. It was about £12.00
It will imobilise one electrical circuit - fuel pump or coil etc.
It has a lock mode so that if you take the car somewhere for a valet or repairs then you don't have to worry about giving out the number.
It also gives you a delay before having to put the number in again once the ignition is off... i.e if you stall the car and have to turn the ignition
on/off you dont have to re-enter the number. You get about 10 seconds i think.
They must surely still do a similar product.
Cheers
G

who? ring?
hmmm, £12 doubt id be able to make that with just the cost of materials.
found what i wanted, a picaxe microcontroller on a project board ready for some tinkering and programming.

Not to bothered a bout been able to programe it, so long as it stops a theving little git!! and is simple and cheap!!! think that i will have a look
into the Ring product as well £12 not bad, if i find it i will let you know, prob get one at cost price.....thats if they are still been made!!

Let us know how you get on with finding one- purely for 'cool' reasons I'd like one myself!

hey bob are you still looking for this immobiliser. ive written the code into the assembler software ready for downloading into the microcontroler
chip. what ive coded into it is:
, when actively immobilising a red LED is on.
press in the correct 4 digit code, the immobilser will connect up an electrical circuit, can be ignition or fuel pump and a green LED will light up.
if the wrong code is put in it will just reset to no code input.
once the immobiliser is active youll get 30 second to switch on the engine. while engine is on you can hold down the asterysk button to get the valet
service. to switch off valet service you have to have the engine off and the car key out.
when switching off the car normally you will get a ten second pause before the the circuit will be immobilised. so you can restart if you stalled.the
red LED will come back on.
as you can see this works much like the £12 imob.
keypad can be placed almost anywhere. anyone else interested in one of these, or would like some mods to it???
cheers

ive pretty much sorted out the design of the circuit now.
before i go any further i want to know whether people are still interested in one of these keypad immobilisers?? its not going to be worth the
development time, right now, if its only for myself, i can do it later on. anyway a rough estimate of cost, looking at the parts im gonna buy, will be
a max of £25. thats a max, if it goes any higher ill stop developement. itll probably be lower but im just giving you a worst case scenario so i dont
upset people.
i know its not quite £12 but then im not buying in bulk!
are there still takers or am i wasting my time?
cheers

May well be interested too. There's a chap on another list fitted one with a sensor on a key-ring to touch onto a socket on the dash. Gonna find out
more and let you know.....
Those chaps on the Yahoo BEC site came up with this:
http://www.abacuscaralarms.co.uk/selca/mc2.htm
Looks the nuts to me, though £40 more...

the one ive got my eye on is on the maplin website, claims its out of stock but will have to see, if it is then ill be getting one similar if
possible. just the basic kypad.

Picked up our Fireblade engine yesterday and the lovely bloke we got it from was good enough to leave £300 worth of Datatool alarm and imobiliser
attached to the loom. Even gave me the remote fob for it!
Sorry this is of no help to anyone here, but its nice to have a little luck every now and then!

well getting through this imob thing, its taking much longer than i thought cause ive had to do work and strip my donors..... itll be done soon tho.
then needs testing.... who wants to let me use their car a guinea pig????

If you still need a car to test it on I'm just sorting out my wiring. Looks like an explosion in a spaghetti factory at the moment - your
welcome to come round plug it in and test it. I'm not too far away from Bucks
