All Fiats which had the code cars removed are registered with the NVRS (National Vehicle Security Register) now called Ratianagroup (

I've had major arguements with FIAT UK over the years regarding this system. I have no problem with the information being removed on import thus avoiding it being left around in show rooms, compounds etc. However once the vehicle has been purchased and registered then the rightful owner should be able to obtain the codes, by supplying proof of ownership etc.. However the NVSR will only release codes to dealers and (used to be/is) AA only. They had no methods to relase codes to the RAC or any international motoring organisation so if your code system failed whilst abroad you were stuffed!
Personally I never sign a sales deal on a Fiat unless the dealer agrees to get all the codes from the NVSR which they can do with your approval.
I store the codes for our cars on my mobile phone as pseudo phone phone numbers. The given 4 digit key/imobiliser code is a sub part of a genuine looking STD / number sequence along with a person name that only I know relates to a given car.
At least if I'm in one of my/our cars, and I have my phone with me, and the key code system fails, then I can recall the emergency code from the phone and key it in via the throttle pedal to get me home.
Finally. You own the car. It is your right (I believe) to have this emegency code. They have it in the rest of the EU.
I pressed my case with Fiat for my wife. She used to have to park in a dark and crappy multistory car park. So the system packs up late at night. She calls the AA. Waits an hour or more. The AA man arrives and starts the car via the emergency code procedure but is not allowed to pass the code/method one. A little while later she accidentally stalls the car in a rough area of town........
What a CRAP system.
I've never won my stance with Fiat so now I just bypass Fiat UK. I have all the code I need and ensure that we can get out of trouble and keep our cars secure.
I would much rather my wife's car to be open to steal and no insurance payable that for her to be left in a dangerous / exposed circumstance.
Sadly Fiat are more happy to let my wife be assaulted than allow her to get herself, in her own car, home quickly and safely.
Go figure.... I would love somebody to take Fiat to court and get soem damages after a) having requested their codes b) being denied and c) being assaulted or otherwise compromised.
