DOM ix TwinStar® double cylinder EXPRESS

"Two roles - double security"

With the ix TwinStar®, DOM once again demonstrates its comprehensive expertise in the field of mechanical locking technology. The new reversible key system is particularly well protected against unauthorised copying by a floating double roller in the key.

DOM ix Twinstar® is a secure locking system for all those looking for the highest quality. It meets the high requirements of VdS, DIN and SKG and can be used in residential buildings, offices or private companies. Thanks to a complex system - 11 spring-loaded locking elements, 10 of which are pin locking elements and 1 locking shaft locking element - it is suitable for private homes up to large buildings with high security standards.

Reversible key with patented movable double roller

It may look like a normal key, but the ix TwinStar is the pinnacle in the evolution of DOM keys. Every technology, innovation and patent for mechanical security ever developed by DOM engineers has resulted in this unique reversible key. It features more complex copy protection technologies integrated into the key and more pins for more security and possible combinations. It also offers the highest level of user-friendliness due to the reversible technology.

Twin caster

It only looks like a small wheel, but the double role in the key of the DOM ix TwinStar is a really big deal. Not only does it make it almost impossible to copy the cylinder unless you have the right special tool, it also generates a large number of extra key combinations, making it a perfect addition to the security system. Best of all, it is still as easy to use as a regular reversible key.

DOM TwinStar key

Impact protection

The cylinder contains impact protection pins and other security elements that prevent access by impact keys to turn the inner pins.

Opening protection

The cylinder contains specially shaped unlocking security pins that prevent opening with the help of a lock pick.

Pulling protection

The cylinder contains a special cylinder core which prevents the cylinder from being pulled out by drilling into the core.
