A licensed locksmith can cut virtually any type of key — from standard house keys and window lock keys to restricted security keys, transponder car keys, and high-security dimple keys. While hardware stores can copy basic keys, a locksmith provides precision cutting with professional equipment, and is the only option for restricted, transponder, and high-security keys.
Overview
Key cutting is one of the most fundamental locksmith services, but modern keys come in many forms — from simple brass house keys to laser-cut car keys with embedded transponder chips. A professional locksmith uses precision key-cutting machines calibrated for different key types, ensuring clean cuts that operate smoothly and wear evenly over time. In Australia, restricted keys (used in many commercial and strata buildings) can only be cut by an authorised locksmith with the key owner's written permission, providing an essential layer of key control. For automotive keys, specialist machines and programming equipment are required. Whether you need a spare house key, a replacement car key, or copies of a restricted key system, a locksmith delivers accurate, reliable results.

How it works
- 1
Key Identification
The locksmith identifies the key type — standard pin-tumbler, dimple, restricted, tubular, car transponder, or laser-cut. This determines the cutting method and machine required.
- 2
Authorisation Check (for restricted keys)
For restricted key systems, the locksmith verifies your authorisation card and confirms you are listed as an approved person before cutting any copies. This is a legal and professional requirement.
- 3
Precision Cutting
The key is cut using the appropriate machine — a standard duplicator for basic keys, a code machine for high-security keys, or a laser/dimple machine for specialist keys. Each key is cut to precise factory specifications.
- 4
Testing & Quality Check
Every key is tested in the lock to confirm smooth operation. The locksmith checks for burrs or imperfections and makes any fine adjustments needed for perfect function.
How much does it cost?
Key cutting costs in Australia range widely depending on the key type. Standard brass house keys cost $5 to $15 each. Dimple keys and high-security keys run $15 to $40. Restricted keys (requiring authorisation) cost $20 to $50 per key plus any locksmith callout fee. Car transponder keys are the most expensive, ranging from $150 to $350 for common vehicles and $300 to $450+ for luxury or European cars — this includes both the cutting and the electronic programming. Basic key cutting is often available while you wait at a locksmith's shopfront for no callout fee. Mobile locksmith key cutting attracts a callout fee of $50 to $100 on top of the per-key cost. Getting spare keys cut proactively is always cheaper than emergency replacement.
Australian regulations
Key cutting in Australia is regulated under security industry legislation. In NSW, a Class 2F Security Licence under the Security Industry Act 1997 is required. Victoria requires a Private Security Licence under the Private Security Act 2004, and Queensland licenses locksmiths under the Security Providers Act 1993. Restricted key cutting carries additional obligations — the locksmith must verify the requester's authorisation before cutting any restricted key, and must maintain records of all restricted keys cut. The Master Locksmiths Association of Australasia (MLAA) sets professional standards for key cutting accuracy and ethical practices, including strict protocols around restricted key management.
