Lockwood Twin
Key Control
Lockwood Twin introduces a new era of key control, from the factory, through a select Dealer Network, to your door.
Legally Protected Keying System
Lockwood Twin™ is afforded two independent forms of legal protection, to best ensure protection against unlawful manufacture and distribution of key blanks and cut keys.
Patents
Strong international patents protect the cylinder lock and key combination, and keyblank of Lockwood Twin. Patent protection ensures exclusivity by legally barring the sale of unauthorised manufactured or imported cylinders, keys or keyblanks. Lockwood Twin is fully patent protected.
Design Registration
The keyblank is protected from unauthorised duplication by registered design of the key profiles.
Physical Security
Pick Resistant Design
Through accurately maintained manufacturing tolerances, high tension pin tumbler springs, spool type top pins and the addition of a second locking mechanism, Lockwood Twin provides a high level of resistance to picking and impressioning attacks.
Drill Protection
Every Lockwood Twin cylinder includes hardened inserts to protect strategic areas of the cylinder from drill attacks.
Security Ratings
The Lockwood Twin keying system achieves the following ratings, according to AS4145.2-1993:
- Keying Security for Cylinders - K6
- Physical Security for Cylinders - K5K6
- Physical Security when attached to Lockwood 3572 Series Mortice
- Lock with standard attack protection - S2

Cylinder Security - Dual Pinning Mechanism
Every Lockwood Twin cylinder includes a dual pinning mechanism, combining a six pin in-line mechanism with a secondary locking side bar, acting on an additional row of pins. The precision machined cylinder mechanism permits vastly increased master keying over traditional systems.
Master Keying
A Lockwood Twin™ master key is designed for your unique keying system. It operates every lock that has been built to your unique specification. With the revolutionary Lockwood Twin mechanism, large and complex keying systems are easily catered for.
Key Control
Every Lockwood Twin keyblank and cut key is protected by strong international patents. Distribution of these keys is strictly controlled by ASSA ABLOY, under legal agreement, via the select Lockwood Twin Dealer Network of approved locksmiths.
