Both locks are pretty much identical, with the exception of anti-drilling inserts - FAB 2** has no anti-drill elements. Also FAB 3*** comes with the identification card, which is only a convenience, because blanks for both are freely available. Both locks have six pin chambers, but the first chamber is left empty. Other than that, everything is identical to the FAB 3*** Profi.
