[databasecar]

I've read recently that if you lose both master keys, you need to have an extensive replacement of the computer components, resulting in a very expensive repair. Is it possible that the codes and other information to make a new master key would be available in the dealer's or Toyota's database ? That is, would this have been programmed in at the factory (or delaer) and could this information be retrieved by knowing the VIN ? Similarly, could one use the valet key as a starting point for accessing such a database, if it exists ? Isn't the code in a key the same unique one as in the master ?
