about us

J. Larsen Pty. Ltd. is one of Australia's oldest locksmith companies. Founded in 1917 in Fortitude Valley (Brisbane) by Danish immigrant, Julius Jens Peter Larsen, it is still very much a family enterprise, owned and operated by the third generation.

From humble beginnings when keys were cut by hand with a file, J. Larsen Pty. Ltd. has grown to a medium sized business employing over 30 staff equipped with computerized machinery to originate keys to code and maintain extensive lock systems. We are also one of the founding members of the Master Locksmiths Association of Australasia (M.L.A.A).

In 1983 a decision was made to invest in lock manufacturing and a factory was established in the Narangba Industrial Estate just north of Brisbane. In 1991 the company established it's head office, retail shop and warehouse distribution centre at it's current location in Albion.  

The company now manufactures it's own range of key blanks, lock cylinders and padlocks under the 'OZ' brand name and our wholesale division supplies locksmiths throughout Australia and New Zealand.

Further innovation led to the development and manufacture of 'OZ' Restricted Security Key Systems and these have now been installed by thousands of businesses across Australia to help safeguard their premises. In fact, 'OZ' has become the benchmark for restricted security keys in Australia.

The company also represents several overseas manufacturers and imports a wide range of lock related products from around the world.

As we head towards our 100th year, our commitment to become Australia's leading lock manufacturers and stockists of allied products in continuing to be fulfilled. As wholly owned family company we work within a framework which guarantees you, the customer, our personal attention at all times.

PILOT BRAIN, of Qantas, was again In the limelight yesterday, when he arrived by 'plane from Bris- bane with Mr. Larsen, lock and safe expert of Chubb and Co., who was required to open the strongroom of the Cairns branch, of the Common- wealth Bank.

Vain efforts had been made, to open the strongroom. The 'plane landed at Hambledon at 4.30 pm., having left Bris- bane at 1.30 p.m. Mr. Larsen was en- gaged until a late hour last night, and the safe was eventually opened, but a hole had to be knocked In the wall. It is believed that the trouble was due to a break down of the combination lock, but officials would say nothing, regarding the matter. Other, Cairns banks sup plied sufficient cash to carry on. The Commonwealth Bank Inspectors are at present in Cairns on the usual inspec- tion.
