My old Honda has an immobiliser key. The handle cracked. The "circuit board" bit could be anywhere between here and there! Luckily, I've a spare. Should the 1st. one not turn up, is it possible to get some sort of similar "circuit board" stuff (tinned copper sandwiching fibreglass sheet) to make up a new one?
That's unless, of course, immobiliser keys for 18 year old cars are easy to get (and cheap!)!

Fleabay is always worth a look for keys and immobilisers etc.

You could try someone like RS or maplin. They usually have circuit board bits. There are companies that will make up boards for you but they are usually geared up for high numbers of orders. Failing that your local college might run an electronics course so there will be some willing students you could ask that could redo the board and solder all the bits back.
Other alternative is to fit an after market immobiliser. Some can be bought quite cheaply assuming you don't one that complies with CAT1 standards. Again I think maplin sell them.

No chance whatsoever of 'making one up' or getting a student to lash one up. Your only hope to to get one from a scrapper or ebay and then code it to your car.
I know that in a Vauxhall you can do DIY training the RF key fob but am not sure about the immobiliser chip. For many cars it is a dealer job. Have a look through a haynes manual or speak to your local auto electician for advice.
If you could lash something up with tin foil or basic electronic stuff from Maplins or the like it would not be a good immobiliser would it??

"Code"? "Chip"? What are these code & chips of which you speak?
The immobiliser key is a flat piece of fibreglass board, about the size of a postage stap, with 5 contacts on each side - it slots into - well, a slot - and the contacts are connected to each other through the fibreglass. When the thing is put into the slot, various connections are made. I suppose I could hard-wire the slot and not bother with the immobiliser key, but I'd rather keep on using it!

The circuit board bit will have a chip on said circuit board. If it was just a piece of fibre glass it's not an immobilser is it?
I'd have thought keys to an old Honda are available through a good locksmith. Our local one could get hold of one for my son's Proton and programme it.

It doesn't, as far as I can see - and I can see the whole thing (well I could before I dropped it somewhere).

There are 10 contacts in total & some are connected to each other. It's a sort of conductive "key".

It's not a real key, though, it's a glorified electrical connector. You can't programme it.

Hi FotheringtonThomas I think the part you are refering to is nothing more than a circuit board with 5 contacts and etched as a key ie a combination of contacts have to be made in order to signal the alarm/immobiliser that the correct key is inserted .The company was Vecta who made this type, we had one fitted to a Mitsubishi and the key contacts eventually wore to point it became intermittent.The security left a lot to be desired but I suppose it was a stumbling block to those that did not know how it worked.I eventually removed said alarm / immobiliser.If you know which of the 5 or contacts are required you could etch one from copper pcb and ferric cloride. was available from places like Maplins.

security (leaves) a lot to be desired but I suppose it was a stumbling block to those that did not know how it worked.
That's the sort of thing. It may be "security by obscurity" these days!

Hurrah! TYVM. I shall get in touch with them (have a spare to copy!).

Sorry for the spelling mistake ferric chloride is still available

Heck! If I buy the smallest quantity possible, I can make at least 60 of these things, sourced at *retail*, for 8 quid!!!
