May I ask in what ways the Exec is different than the Protec cylinder? Is the Exec just as pick resistant as the Protec? I would bet not.
older technology. As a patent comes to the end of its life, companies have to keep up with key control issues and generic blanks, so they make newer models, like Medeco making the M3, or Abloy making the Protec. Security concerns are also addressed in new lock models from all sorts of lock makers.
Han Fey has written a ton of Abloy papers that can be found on the TOOOL.nl site. They'll explain a lot of the differences, and hopefully answer your questions.
Enjoy the papers:
