Home security services focus on evaluating and strengthening weak points in a property to reduce the risk of intrusion.

These upgrades enhance the strength of entry points by installing more secure locking mechanisms, making it harder for intruders to force entry.

Installing locks on windows and sliding doors adds an important layer of protection to access points that are frequently targeted during break-ins.

A comprehensive inspection of the property is carried out to identify security vulnerabilities and recommend practical solutions to improve safety.

What is a smart lock?

Smart locks allow users to control access using PIN codes, apps, or biometrics instead of traditional keys.

Proximity and smart key solutions offer convenient, keyless access for both homes and vehicles. These services are especially useful for people who want to streamline entry without relying on traditional keys. Whether it’s through RFID-enabled car keys or app-based home locks, the goal is to make secure access simpler and more flexible.

Involves configuring keys that use transponder or RFID technology, allowing the vehicle or door to recognise and authorise the key without direct contact. This service is commonly used for newer car models and electronic residential locks.

Include duplicating existing fobs or disabling them when lost or stolen. These fobs are typically used in keyless car systems and residential complexes, relying on near-field communication to trigger entry.

These give users the ability to control door access through their smartphones. Depending on the model, these locks can be operated remotely, and some offer features like activity logs or temporary guest codes.

Provide access using either a numerical PIN or biometric data. These systems are common in both residential and commercial properties and are ideal for those wanting to avoid physical keys altogether.

This service will diagnose and fix issues such as unresponsive keypads, connectivity problems, or battery failure in electronic locks.

What happens if a proximity key is lost?

If a proximity key or fob is lost, it can be digitally removed from the system to prevent unauthorised use. A replacement can then be programmed to match your lock or vehicle.

Are smart locks compatible with older doors?

Yes, most modern smart locks are designed to fit standard door sizes and can be installed on existing hardware without major modifications.

Is internet connection required for smart lock operation?

Not always. Some smart locks work offline using Bluetooth, while others may require a connection to Wi-Fi or a hub like Zigbee for full functionality.

Restricted master key systems are designed to provide tiered access throughout a building or property. These systems allow different users to access only the areas relevant to them while a master key can open all designated locks. To maintain security, restricted keys are cut on protected keyways and cannot be duplicated without proper authorisation.

One key aspect of these systems is access control design, which involves creating a structured hierarchy of access levels tailored to different roles, departments, or zones within a property. This ensures that staff or tenants only have access to the spaces they’re authorised to use.

Necessary when employees leave, tenants change, or when key security is compromised. Rather than replacing the entire system, the existing locks can be adjusted to work with a new set of keys.

To support accountability, key tracking is implemented. This involves maintaining a central registry that records who has which key, helping reduce the risk of lost or misused keys.

Allows the existing master key setup to grow with the property. New doors, zones, or locks can be added without overhauling the entire system.

Used to prevent unauthorised duplication. Only approved locksmiths can cut these keys, and only with written consent from an authorised individual.

Can restricted keys be copied at a hardware store?

No. Restricted keys are protected by design and can only be duplicated by licensed locksmiths with proper authorisation.

Can more areas be added to an existing master key system?

Yes. These systems are modular and can be expanded to include new zones or rooms as needed.

What should be done if a restricted key is lost?

It’s recommended to rekey or reconfigure the affected locks to prevent unauthorised access using the lost key.

Automotive locksmith services cover a wide range of solutions related to vehicle access, ignition issues, and key replacement. These services are designed to help drivers regain control over their vehicles, whether they’re locked out, have lost their keys, or are experiencing ignition problems. Support is available for most common makes and models, with tools that allow on-the-spot assistance.

One of the most common tasks is car unlocks, which involve safely regaining access to locked vehicles without causing damage to the door, window, or lock.

Provides replacement or duplicate keys, including those with transponder chips and remote functionality. This is useful for both lost keys and spare key requests.

Ensures that the new or duplicate key can communicate properly with the vehicle’s immobiliser system. Without this programming, the key may physically turn but the engine won’t start.

Involves replacing worn-out or broken plastic casings, as well as fixing unresponsive buttons on remote car keys. This is often more cost-effective than replacing the entire key.

Can a new key be made without the original?

Yes. A new key can be created using the vehicle’s lock code or Vehicle Identification Number (VIN), depending on the model.

Are newer car models supported?

Most late-model vehicles are supported, as mobile locksmith units carry the necessary equipment to program and cut keys for a wide range of makes.

What happens if the ignition won’t turn?

If the key won’t turn in the ignition, it’s often due to a worn barrel or internal mechanism. A locksmith can usually repair or replace the ignition on site.

Automotive Transponder — A chip embedded in modern car keys that communicates with the vehicle’s immobiliser system. These can be replaced or reprogrammed without needing to visit the dealership.

Barrel — The cylindrical component of a lock where the key is inserted. Rekeying involves changing the internal pins of the barrel so it works with a new key.

Bump Key — A specially cut key used to manipulate pin tumbler locks. While often exploited in bypass techniques, it highlights the importance of bump-resistant locks.

Cylinder Lock — A common lock type that uses a cylindrical mechanism turned by the correct key. These are frequently rekeyed or replaced in residential and commercial settings.

Deadbolt — A type of lock bolt that is not spring-loaded and offers higher resistance to forced entry. It is commonly used on external doors for improved security.

Key Blank — An uncut key ready to be shaped to match a specific lock. These are used for duplicating house, commercial, or car keys.

Keyless Entry — A system that allows access without a traditional key. Entry is managed via PIN code, smartphone, or fob.

Latch Guard — A protective metal plate installed on a door to shield the latch and prevent prying attacks. Often recommended for exterior doors and gates.

Lock Rekeying — A method of changing a lock’s internal configuration so it works with a new key. This does not require replacing the entire lock.

Lockout — An event where access is lost due to missing, damaged, or locked-in keys. Emergency services can provide non-destructive entry.

Master Key System — A keying system where multiple locks can be opened by one master key, while individual keys open only specific locks. Useful in commercial settings.

Mortice Lock — A lock installed inside a pocket within the door rather than on its surface. Common in older Australian homes and often used for enhanced security.

Proximity Key — A wireless key that allows a vehicle to be unlocked or started when nearby. These are programmed and duplicated using electronic tools.

Reinforced Strike Plate — A strengthened metal plate fitted to a door frame to hold the latch or deadbolt. Designed to resist forced entry by increasing structural support.
