Interesting key and immobiliser poser
My new build uses a Cinquecento column and Scooter electrics. The scooter immobiliser uses a chip in the key to disarm and a coil that clips to the
ignition barrel to pick up the signal. The fiat column has an ignition lock permanently fitted which also has a coil so presumably a chip in the key.
The scooter loom also has a start button.
What am I best doing? I want to keep the piaggio immobiliser (tampering is too much trouble) but can do without 2 key switches. I can wire the Fiat
ignition switch to the power but I'd still have to put the piaggio key in the slot to immobilise. Can you suggest a neat solution?

If its an Rdif chip then if your carfull you could swap them. Ive done a few ford keys.

Tape the transponder chip from the removed from the scooter key close to the antenna coil.

I'd thought about fixing the scooter key's chip to the coil permanently but then it isn't an immobiliser. The Fiat key is
over-moulded so the chip can't be removed. I'm not sure if the two would interfere. I guess I could try it.
Is there any way I could "nuke" the fiat key to kill the transponder? I still wouldn't have the Piaggio chip in the Fiat key.

How about a few secs in the microwave, would be bound to destroy the chip.
Or could you remove the blade from the Fiat key and fit it to the Piaggio one?
I think the antenna coils work at a standard frequency so using the Fiat one should be ok.

I don't see that nuking the chip would help, you would still have the immobiliser in the column and without the code from the key you'd be
stuck!
Attaching the key fob to the column would permanently disable the ignition lock and shouldn't interfere as they would use different codes.
Is the fiat column an ignition lock or a steering lock?

The second transponder will simply be ignored.

Chop the offending key and use the plastic portion as a keyring only.
Beware of what you wish.. for it may come true....

After exhaustive "before" and "after" testing I've found that the fiat key does interfere with the Piaggio key -
immobiliser communications. I'll either have to make a Frankenstein key using the blade from the Fiat key plus the chip from the piaggio key or
nuke the Fiat immobiliser chip and use the Piaggio key as a key ring as suggested.

I dont think the keyring idea would work as the chip has to be within the transducer coil and close to it, I experimented a while ago with my rovers
imobiliser and found that putting the chip next to the steering lock would not work reliably.
