For mechanical security you can trust, look behind the key

Behind the key lies a world of unseen importance. ASSA ABLOY, with a rich history of lock and key innovation spanning over a century, leads the way in developing trusted locking technologies.

Mechanical cylinders history and innovation

Every time mechanical security locks the door or another opening – at home or work – a keyholder puts their trust in the technology, security knowledge and heritage of its manufacturer, now and far into the future. Choosing locking is a decision for the next few decades, after all.

Millions of customers trust ASSA ABLOY

ASSA ABLOY’s history of inventing locks and keys stretches back more than a century. Since the invention of the pin tumbler by Linus Yale, ASSA ABLOY Group brands have led the way in developing locking technologies which inspire customer trust.

The Euro Profile Cylinder – first patented by an ASSA ABLOY company in 1928 – has become the gold standard in mechanical door security, in Europe and beyond.

This decades-long track record of quality and reliability earned ASSA ABLOY mechanical locking solutions the trust of businesses and homeowners worldwide.

Working together with a vast global locksmith and security partner network, ASSA ABLOY provides the service in master key system design to make sure customers get the right solution every time.

These tailor-made master key systems – plus keyed-alike and keyed-to-differ options – provide the flexibility to secure any premises with affordable mechanical locking.

Precision engineered, high-quality mechanical security

ASSA ABLOY’s comprehensive product range meets the security needs of almost any industry or opening, beyond just doors – from monumental glass entrance doors to tiny micro-switches.

Mechanical locks are available for any budget and almost every interior and exterior opening, helping organizations implement a key system with maximum flexibility and intelligence.

To bring these solutions to a global market, advanced production technologies combine the highest quality of construction with materials chosen for durability.

For peace of mind, most ASSA ABLOY product lines offer enhanced protection against existing security threats, from pulling and picking to drilling, bumping and cylinder snapping.

Rigorous in-house and third-party testing pushes ASSA ABLOY’s mechanical solutions to their limit, to ensure customers can rely on every lock to meet or exceed national and international security standards.


For now – and for the future

Even as ASSA ABLOY develops new products at the leading edge of electronic access control, R&D investment continues to foster innovations in mechanical security, too.

ASSA ABLOY’s active patent strategy adds even more peace of mind. Patent protection for many mechanical key systems stretches into the 2030s. This makes it illegal to copy ASSA ABLOY keys without authorization.

Property owners and building managers sleep easily at night, knowing the risk that their keys fall into the wrong hands is much lower than with an off-the-shelf solution.

Expert service over the lifetime of a system, and the option to extend or modify coverage, future-proofs mechanical solutions for a world in which access needs are always evolving.

The same care, innovation and quality goes into everything ASSA ABLOY creates today – and will continue long in the future.


Every time an ASSA ABLOY customer locks their door, they can be confident in what’s behind the key, too.
