The unique design provides up to 133 million possible lock-opening combinations — an immense number that allows the implementation of complex security hierarchies while minimising the chance of phantom keys.
EVVA’s patent-protected, SCEC-approved security also makes keys difficult to duplicate without authorisation, and locks nearly impossible to pick or bypass. Yet a low cost per lock means DPS is the most affordable high-security masterkey system available.
Since EVVA’s foundation in 1919, the Vienna based family owned Austrian company has grown rapidly to become Europe’s third largest
manufacturer of keying systems.
EVVA’s name derives from a drive for invention, experimentation and application that has underpinned its reputation as a leader in the development of ground-breaking security technology.
A byword for security, EVVA has filed applications for more than 140 national and international patents over its 90 years of operation. It is the first to attain ISO9001 certification for quality in design and production.
EVVA is exclusively distributed in Australia by the Davcor Group — one of the largest distributors of hardware and security in the southern hemisphere.
Davcor works with a network of more than 85 locksmiths across Australia and New Zealand that are the only people in Oceania authorised to install and service EVVA masterkey systems.
Each key has a number of side cuts. Cylinders contain a key sidebar with matching notches. When a user inserts the correct key, the sidebars cut into the key line up with those etched into the broach in the cylinder. This allows key rotation and the lock to open.
It is extraordinarily difficult to reverse engineer DPS. Moreover, three separate systems guard against key tampering and illicit copying by staff, visitors or contractors:
Only authorised locksmiths can manufacture keys for their masterkey systems, with the correct proof of entitlement.
Through patents and licensing, EVVA restricts the manufacture of DPS keys to a small number of authorised locksmiths.
Key reproduction cannot occur without specialised and expensive machinery.
The DPS system delivers such robust security that keys are difficult to illicitly copy, locks are extremely difficult to pick or bypass and phantom keys are nearly impossible. This is why it’s the masterkey system of choice for industries and organisations that demand superior security.
DPS is a high-security lock system that uses patented technology to minimise intruders’ ability to tamper with, pick, or bypass the lock.
Ease of use.
Rounded key contours and Teflon-impregnation make DPS keys easier to use.
Long-life, anti-wear parts.
The combination of precise manufactured components is why DPS locks have been cycle-tested to 100,000 operations.
DPS cylinders can be crafted to suit almost any lock or door, including those of other leading brands.
Three level anti-copy protection.
Patents (DPS is patent-protected till 2022), many varieties of key profiles and keys can only be manufactured by the approved agent
Hardened metal elements provide exceptional resistance to drilling, impact, or plug-pulling attacks.
Low chance of phantom keys.
The use of sidebars and sliders means DPS scales to a huge size without phantom keys compromising security.
Australian Standards SC8 AS41452 Approved
EVVA can also produce cylinders to suit cupboard locks and T&L handles, padlocks, pushlocks and camlocks plus cylinders for keyswitches and rollerdoor locks.
All EVVA cylinders are cycle tested to at least 100,000 operations. Cylinders also meet the highest standards for corrosion and fire resistance, and can operate normally in temperatures from -20 degrees Celsius to 80 degrees Celsius.
