Euro Cylinder locks are today’s most popular locking systems amongst locksmiths and architectural ironmongers.Įuro cylinder refers to the profile of the lock – this is a cylindrical lock, which can feature up to eleven pins within its cylinder. Multiple Keyed Alike sets can be specified providing increased flexibility in master key systems.A Euro Cylinder lock, or ‘pin tumbler lock’ (as it was originally known when patented in 1805), is used primarily as a locking medium to operate a lock case. Keyed Alike cylinders (KA) are a set of locks that can be operated by the same key and relevant master keys. Common entrance cylinders can be incorporated as part of a master key system.Ī Keyed to Differ (KTD) cylinder can only be operated by its own unique key and relevant master keys. This can be suitable for maintenance companies or milkmen needing access to building corridors. Keys can also be issued that allow access only to common entrances. Normally used in blocks of rented apartments and halls of residence, individuals must be able to unlock one or more main access doors without direct access to neighbouring apartments. Level 3 - The sub-master key’s (SMK) unlock specific departments or areas within one of the buildings.Įach cylinder will then also have its own differ key which will be used by the person who works in that particular room or office. Level 2 - The master key’s (MK) will unlock all cylinders within a specific building on the site. Level 1 - The grand master key (GMK) unlocks all cylinders on all sites. On the bottom level employees will need access to their particular office or working area.Īs an example there are generally three levels that exist within a typical GMK: On the middle levels, management and small teams require access to only their certain areas. On the top level of the system, head of departments and managers may require unrestricted access to large areas of the building. Within large organisations, clear and well defined structures are essential. For added convenience master key systems can also incorporate our office furniture locks and other industrial application locks. A master key will allow access to every cylinder within the system, which is highly convenient for a Managing Director or an Executive as they then have access to any area within the building. In private homes and small to medium sized businesses access to all areas is often restricted to a select number of individuals.
