immo on fiat sedici

[pagatti]

hi all...
yesterday i changed battery in door remote control on my Fiat sedici.
I tried to start the car without electronic part (right in the photo) in it and the car started!
I was thinking that immo was in the right part of the key...
it is correct?
or the right part is only for remote control and the immo is in the left one?
However, I have only one key (used car, bought without 2 keys), and I've experimented lot of difficulties of having another one from Fiat (lot of money, basically). Can someone help me, I'm able to read ECU with MPPS or Fiat Ecu Scan...

That Fiat uses Suzuki SX4 immo and key.
You will not be able to do a spare chip with the tools you have.
Go to a locksmith in your area and ask him do do you a spare key or if he can't buy a key with chip form him and go to dealer to program it.

thanks for the answer, more or less is what I knew...
but phisically, which is the part of the key that "speaks" with the car?
I was thinking that it was the right part with the battery inside and electronic in it, but the car runs also if you take the part with buttons out of the key....
