Thanks guys, it was a bit difficult to accurately express my question at first but you definitely answered what I was after.
When I first saw the car (without any keys) everything was locked up. First we used a coat hanger to unlock the driver's door, but turns out that door latch had a broken pawl and even after getting it unlocked it still would not open from the outside handle. So then we unlocked the passenger door with the coat hanger. From there we could open both doors. However the levers for the rear trunk and engine cover were also locked. Next we discovered someone had previously drilled a hole behind the license plate (as Karl describes) so we were able to 'jimmy' the trunk open. Unfortunately the emergency cable was broken, so had to remove the service access panel between the trunk and engine bay. From there we could reach through and unlatch the engine cover. The glove box lock is broken so no problem there, but the ignition cylinder (and therefore steering wheel) was also locked. In order to turn the steering wheel to move the car I had to drill out the non-removable bolts from the lock housing and remove the entire ignition lock assembly. What a long, frustrating process. But still faster (and likely less frustrating) than waiting for AAA to come unlock it (IF they could).
Back to the keys issue. Wow Karl, excellent display and explanation of the various keys, thanks! Given the way Fiat does things I honestly would have thought there might have been only one or possibly two key options for all Fiats over all years. When you look at online sellers of blank keys they usually only show one option that reads "fits Fiats". There is never any identification or clear photos or description to tell which Fiat key they are offering. So how do you get the right one? Especially when you don't have any original keys to compare with? Is it possible to identify the proper blank numbers (for the doors and the ignition) by the year of X or by some code on the lock cylinders? The door cylinders have a 4 digit on the ends but I don't see any code on the ignition cylinder (might have missed it, will look again).
I will be taking them to my locksmith to get keys made but I know from experience that he likely does not have any Fiat blanks on hand. Usually if he does have the blanks he can do the job while I wait, but if he doesn't then I'll have to return after he orders them (and he is in CA while I am in NV, so not convenient). That's why I was hoping to pre-purchase the blanks.
I guess I will find out when I see the locksmith, but does anyone know if the ignition cylinder can be reconfigured to use the same key as the other locks? Given the blanks have different profiles it won't be easy like with other makes, where all cylinders fit the same key blank so the little tumblers (pins? or whatever those little blades are called inside a lock cylinder) can be swapped for ones to match an existing key. But not sure if they can change the actual cylinder profile to accept the same blank? Although I like to do most things myself, some things I leave to specialists and locks aren't my thing.
Thanks again.
