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.
TD60: your first line of affordable defence
If you want to improve your home security without any hassle, the TD60 is a practical and reliable option. It is designed for homes and residential complexes seeking an extra level of protection against forced entry.
Its robust design and patented key make unauthorised copying difficult, giving you complete control over who can gain access. Thanks to its smooth and durable operation—with a service life exceeding 100,000 operations—it offers consistent security without compromising on convenience.
What’s more, its compatibility with shared systems means that several people can use the same key to access the entrance, storage room or garage. A simple solution to make everyday life easier without the need for major changes.
TX80: greater control and durability for your home or business
When you’re looking for more than just basic protection, the TX80 takes security to the next level. It is designed for homes, commercial premises or workshops that need to protect tools, materials or valuable belongings with a higher level of security.
Its internal multi-point technology reinforces the cylinder against impacts, drilling or attempts to remove it, making any tampering difficult. It also comes with a proprietary card that guarantees full control over key duplication: only the cardholder can authorise copies.
The TX80 comes with five highly durable metal keys and is available in a range of sizes and finishes, making it a versatile and long-lasting option for easily reinforcing any door.
TK100: maximum security for areas with multiple access points
The TK100 is TESA ASSA ABLOY’s most advanced option. Ideal for buildings, offices or residential complexes with multiple doors and different users.
Its built-in technology protects it against any form of tampering and allows you to manage access using a single key for the entire system: entrance, garage or storage room, depending on each user’s access level.
This gives you peace of mind and total control with a solution tailored to your needs.
Key Manager: peace of mind on your mobile
Have you lost a key or are you worried about unauthorised copies? At TESA ASSA ABLOY, we’ve launched Key Manager for TK100, TX80 and T70: register your cylinders, track copies and receive instant alerts if someone requests a new one. Deactivate lost cards with a single click and view the full history. The included QR cards make everything easier, ensuring simple and secure management from anywhere.
Keying and hybrid solutions with COMBI RFID
At TESA ASSA ABLOY, we offer master key systems for the TD60, TX80 and TK100 models, allowing you to open whatever you need – your front door, garage or office – with a single key, without having to carry a bulky bunch of keys.
Furthermore, COMBI RFID keys combine mechanical security with proximity technology, bringing together the best of both worlds. They are the ideal solution for businesses moving towards digitalisation without having to replace their entire system.
Easy to install and simple to maintain
Our cylinders are easy to install in standard Euro-profile doors, without the need for building work or complicated modifications. They are available in stylish finishes, so that security complements the design of your door.
Each model uses original, durable keys, designed to ensure smooth operation for years to come and to maintain their certified service life.
It offers practical, discreet security that fits seamlessly into your daily life without any hassle or extra maintenance.
Security that looks to the future
At TESA ASSA ABLOY, we turn locks into proactive allies: proven security, controlled keying and digital management for what really matters. We plan your security so you can control who enters, how many keys there are and how your security evolves. It’s not just a lock; it’s peace of mind that anticipates risks and adapts to the future.
