ABLOY PROTEC features long lasting legal and physical protection against unauthorised key duplication, a full metal, colour coded key, and the recognised ABLOY attributes of physical security and durability.

ABLOY PROTEC is recognised as the premium high security mechanical lock system available, and is used extensively by private, commercial and government end users who demand the ultimate in high security master key systems.

ABLOY PROTEC is SCEC Endorsed for Secure Area Applications. The strong, one-piece metal key ensures against expensive on-going key replacement, and the absence of pins and springs provides unmatched resistance to wear and corrosion of internal parts. ABLOY products are built to last.

ABLOY PROTEC is distributed through a highly restricted dealer network. The ABLOY PROTEC dealer network is made up of locksmiths who represent the highest level of professionalism and ethics in the industry. While all locksmiths rely largely on ongoing service of systems for their revenue, ABLOY PROTEC distributors recognise the needs of the end user in relation to product reliability and durability, and respond to those needs by promoting the ABLOY product.


The unique, patented construction of the ABLOY® PROTEC rotating disc cylinder makes it virtually pickproof. Keys and discs use a new principle where cuts are made on two different radii. In addition, the return bars block the discs at 90° if the key and cylinder combinations are not identical.

The ABLOY® PROTEC cylinder not only meets but exceeds international standards for high security including UL 437 and EN 1303.
1.97 billion different key combinations per keyway make it possible to create extensive master-key systems that fulfil your precise specifications.
