Difficult to Conquer

Thanks to its structure and conformation, the rotor offers unparalleled resistance to any manipulation attempts.

In addition, a manganese steel plate is optionally available, which protects the lock from conventional burglary and perforation attempts.

Unique key

OMEGA® locks are supplied with keys with relevant Ownership Cards on which the indirect code is stamped for any key duplicates.

The presentation of the card accompanied by the key allows duplicates to be obtained at the authorized Mul-t-lock Center.

Certification and Patent

The OMEGA® security platform is a Mul-T-Lock® exclusive, certified and fully patented, guaranteeing the highest level of security, thanks to the "protected duplication service" and 7 UNI EN 12209: 05 certification

Re-encryption and Reversibility
The number of OMEGA® lock combinations exceeds 10 million. In case of loss of the key or for security reasons, it is possible to cancel or modify the combination twice, ensuring three "screws" to your lock, always maintaining the High Security level of the product.
