-They do not make a 1 to 1 copy. They read the cs data from a working key.
And by having a working key, they can read the ezs data, and ecu, by obd.
The transponder 8E, is only good for starting the vehicle.
The remote keyfobs that come with a pcf transponder print can be learned the same way.
A SVDI can do this job, or even a datasmart3+ for less then 800 dollar.
Then, several locksmith expresses different viewpoints and begin to discus.
Q: to be more precise working key let access to read data from ezs, it is not possible to read any important data from megamos 8e.
A: The 7th byte from a working key. even from a 8E.

Q: not technically reading from the key, it goes through the 256 combinations of the 7th byte and uses the key to validate the correct one. And audi have 12byte in 8e transponder.
A: In case of a unknown 7 byte, and no working key. In that case it will run true all the 256 Combs. Specialy used with micronas 2006/6 up. But we are talking about audi ezs.
This is not neccesary when you have a working dealer key.
And there is also a keyless go, kessy, system on some of these models.
These are done with a programmer. Even with all keys lost.

Q: I mean you are not reading the cs from the key.. tools like tango pro that search for the 7th byte are actually running through the 256 combos and will use the transponder challenge/response to see if the byte is correct.
