Lost My Last Key for Door Lock.....
My keys have a metal tag on them with the stamped code, but if that has been lost, you'll have to rely on the vin. # or if you have friends with spiders, have them try their keys, if you get lucky and find one that works, you'll then know which key you need without removing the lock.
One other thought, if you have Triple A they will make you a plasticized key that has limited number of uses, but you could take that to a locksmith and have a new one made.
You'll probably end up taking the lock to a locksmith and having one made unless you know of an Alfa dealership that kept that information by vin. # like many of the manufacturers/dealerships have access to and won't release short of your birth certificate and proof that you were born in the U.S. because so many cars were stolen that way.
