DOM ix Saturn


"limitless possibilities"

The DOM ix Saturn locking system guarantees a high standard of security. The basic mechanical system can be modularly expanded with electronic components, thus combining the advantages of mechanics with the benefits of electronics - according to individual customer requirements.

This system is available for reorders only.

For new systems we recommend the successor series DOM ix TwinStar®.

DOM ix Saturn

  • solid pin locking elements made of special brass or hardened steel
  • standard drilling protection
  • optional highest possible VdS class BZ+ (with modular design)
  • single/ keyed alike locks with emergency and danger function (locking on both sides)
  • up to 10 solid profile control pins
  • 13 mm core diameter
  • one-piece cam made of sintered steel
  • locking security class according to DIN EN 1303:6

  • VdS security class 3
  • patent protection until 2023
DOM ix Saturn cutting cylinder


  • cylinder body made of solid brass
  • finish: dull nickel
  • reversible key system
  • horizontal key insertion
  • half cylinder: cam position adjustable in 8 positions
  • half cylinder: cam is delivered in 7.00 o'clock position, can be moved to all positions in 45 degree increments
  • compatible with DOM electronics (made possible by integrating passive transponder technology into the key bow via clip tag)


  • key thickness: 2,4 mm
  • nickel silver reversible key: corrosion-free and low-wear
  • active copy protection through movable rolling elements in the key tip (patented), making it difficult to make duplicate keys
  • 45° float movable roller makes the production of key copies almost impossible
  • no key blanks available on the market

Operational area:

  • single family houses with high protection requirements
  • apartments
  • medium to very large companies
  • public buildings

Options / Special equipment:

  • different cylinder finishes (polished brass, oxidized bronze)
  • increased drilling protection + modular design = VdS BZ+ (VdS***)
  • freewheel
  • weather protection
  • 2-in-1 system

Explanations on the optional extras:

Drilling protection VdS BZ+ = high safety for special requirements:

in cooperation with the police, VdS Schadenverhütung GmbH has developed a star system that divides mechanical locking systems into three different security classes, thus providing you with a quick overview of the respective security level.

  • recognition by VdS Schadesverhütung GmbH
  • VdS checks locking systems and awards recognition from A to BZ+
  • drilling protection VdS BZ+ = VdS security class 3
  • VdS BZ+: increased protection against drilling and core pulling due to carbide pins in cylinder body and cylinder core arranged in several planes
  • this drilling protection variant is manufactured in modular technology with increased tear-off protection
  • modular design as 2-in-1 variant has drilling protection VdS BZ

Cylinder finishes:

  • finishes (polished brass, oxidized bronze)
  • standard finish: dull nickel
  • for individual design requirements
  • if desired, homogeneous appearance of door cylinder and fitting
Please note:
If a different cylinder finish, different from the standard finish, is ordered, extended production times may occur.

Seawater resistance:

  • for use under marine climate or salty atmosphere
  • fixing screw pure brass, cam sintered steel (chemically nickel plated)
  • cylinder finish: matt chrome
  • restrictions possible in combination with other optional equipment
  • in combination with freewheel: clutch not protected against seawater


The profile cylinders which have a freely rotating cam are designated as freewheel cylinders.
The cam can be moved freely through 360° when no key is inserted. DOM freewheel cylinders comply with DIN EN 18252:2006-12.
When the key is inserted, the spring-loaded clutch engages in the cam. This then allows the cylinder to be closed in the conventional way with the key.

  • from cylinder length: 35,5/35,5 mm
  • Usually only necessary for special panic or automatic locks. If in doubt, please check with the door manufacturer.
  • for multi-point locks with panic function: latch and bolt must be moved into the lock body when the door is closed with the handle. To ensure this, the cam must be able to turn freely.
  • in motor-driven locks and special escape door locks
  • restrictions in combination with other special equipment possible
  • with this option the cylinder has no emergency and danger function
  • freewheel function is tested according to FZG (test guideline for profile cylinders with freewheel function for gear locks in escape door locks)

2-in-1 system:

The DOM system is prepared at the factory for a second lock, which the customer can call up himself if required. With the second set of keys the locking cylinder can be easily recoded. A 360° turn in the cylinder - and the new lock is activated. The old keys are thus easily rendered ineffective.

  • 2 x 3 keys, 2-in-1 recodable
  • number of keys per key set selectable
  • with this option standard drilling protection VdS B, with modular design VdS BZ
  • please note that it cannot be reset! After the 1st locking with the 2nd key set, the 1st key set is deactivated forever!
