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 ?

Yes, your new keys have to be programmed at a Lexus Dealership. Depending on the year and model you have, the computer will have to be replaced in order to have the news keys programmed. If that's the case, contact your local dealership, as Lexus should cover the cost of the new computer if its the first time this has needed to be done. You are required to order 2 new master keys and pay for the labor to install the new computer, usually an hour. If you happen to have one of the newer models, you only need to order new keys.

If you have further questions, you can call me and I can try to explain it better for you.
