Abloy has created five generations of key systems, with significant security and reliability improvements every time. The following photos show the oldest system first, the Classic, with newer key systems after that. The current generation is called Protec and is what you will find on this website. The Abloy Protec key is not shown below, but can be found by clicking on the Keys category on the left.

For additional information on the Abloy systems and their history, I recommend reading the following PDF files, written by Han Fey, a lock collector in the Netherlands. The documents are very detailed and cover all the systems mentioned above, as well as the Abloy Protec system we sell on this website.
