10 Years Warranty

Register your new cylinder

Guarantees and statutory warranties are often confused. The statutory warranty of 24 months is a legal requirement. The seller guarantees that the goods sold are free from defects. However, the guarantee is an individual agreement which governs what damage is covered by the guarantee, and what services are provided in case of complaint.

We give you the option of taking out an additional warranty in addition to the statutory warranty for a period of 10 years for the following products.  

DOM Mechanical Cylinders


The additional warranty on DOM mechanical cylinders is available for:

  • DOM Diamant in a coded single lock
  • DOM ix TwinStar in a coded single lock
  • DOM ix TwinStar in a coded single lock 2-in-1

A prerequisite is that you must register here within 1 month of purchasing the coded single lock or locking system.
Go to and select the menu item for locking system or coded single lock. Please fill out all fields as indicated. After receiving your registration and checking the data, the warranty certificate will be sent to you by post.
