does the immobilizer work by making a metal contact with the metal on the jdm key?

or does it emit some sort of a signal?

i'm guessing it (the immobilizer chip) only has to make contact with the metal on the key.

can you enlighten me?

thanks in advance!

 

It doesn't have to make contact with anything; it just has to be positioned in the key head in the same relative position as in the stock key. The immobilizer emits nothing -- it's just read by the ECU through the ignition system, I think. You might want to check these threads:
