What is DPS?
| EVVA DPS — the high security key system without the high cost

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.

Who is EVVA?
| One of Europe’s leaders in masterkey security

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.

At a glance: The DPS masterkey advantage

Patent protected, until 2022

As many as 133 million possible key combinations

Implement a complex hierarchy without phantom keys

SCEC approved for government facilities

SC8 AS4132.4 compliant

Anti-intrusion case-hardened components

Excellent price-performance ratio

Retrofittable cylinder range


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.

EVVA DPS how it works

Three levels of key control

It is extraordinarily difficult to reverse engineer DPS. Moreover, three separate systems guard against key tampering and illicit copying by staff, visitors or contractors:


Controlled protection.
Only authorised locksmiths can manufacture keys for their masterkey systems, with the correct proof of entitlement.


Legal protection.
Through patents and licensing, EVVA restricts the manufacture of DPS keys to a small number of authorised locksmiths.


Technical protection.
Key reproduction cannot occur without specialised and expensive machinery.


A masterkey system to protect any facility in any industry

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.

High-security design.
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 components.
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.
