How can you improve security in businesses and homes with patented lock cylinders and uncopyable keys?
Last updated: 17 February 2026
Security starts with an everyday item: the lock cylinder. At TESA ASSA ABLOY, we know this all too well. Whether in private homes, block of flats or small businesses, having a reliable locking system is essential for protecting what matters most.
Today, break-in techniques have evolved. Methods such as bumping, lock picking or drilling allow a lock to be forced open without leaving any visible trace. That is why, at TESA ASSA ABLOY, we develop patented cylinders and uncopyable keys that combine advanced mechanical protection with total control over key duplication and digital solutions that facilitate day-to-day access management.
From standard locks to high-security locks
Basic lock cylinders are still used in many homes and businesses. These models can be easily opened without the need for force, making the lock the weakest point of the door.
At TESA ASSA ABLOY, we work to eliminate these vulnerabilities. We develop solutions designed to withstand the most common methods of intrusion and keep access secure at all times.
Our high-security cylinders, certified to the EN 1303 standard, incorporate internal defences against bumping, extraction and drilling.
Thanks to their advanced design, they offer a superior level of protection without the need for complex modifications to the installation or altering the day-to-day use of the door.
