Emergency Locksmith
Our 24/7 emergency service responds to residential and commercial lockouts within one hour across Melbourne. Certified technicians use advanced tools to resolve lockouts without property damage, prioritising immediate access restoration while maintaining security integrity. Customers receive expert advice on preventing future incidents through upgraded locking systems.
Commercial Security
Tailored security solutions protect Melbourne businesses from theft and unauthorised access. We install high-security locks for retail premises, industrial facilities, and office spaces, including restricted key systems and electronic access controls. Our assessments identify vulnerabilities in existing security infrastructure, recommending cost-effective upgrades that comply with Australian safety standards.
Automotive Key Services
Specialist mobile units program transponder keys and replace lost vehicle keys on-site. Using diagnostic equipment, we create functional replacements for modern vehicles while repairing damaged ignition systems. This service operates across Melbourne's metro area, minimising vehicle downtime through rapid response and same-day key programming.
Key Cutting
Precision key duplication and repair services maintain security across residential and commercial properties. We cut keys for standard and high-security lock systems, including restricted profiles requiring authorised access. Our technicians also rekey existing locks during property transitions to maintain security without full system replacement.
Security Systems
Integrated security installations combine physical locks with electronic monitoring for comprehensive protection. We supply and install alarm systems, CCTV, and access control solutions compatible with residential and commercial environments. These systems deter criminal activity while providing real-time alerts through smart technology integration.

The team at Top Lock Locksmiths were prompt and the only ones to respond to my online query during lockdown. I recently moved into a new property where the previous owners didnt leave keys for a couple of locks. After a quick email exchange and online quote, Top Lock were able to send someone to replace a lock and cut some keys. The team were professional and efficient. Would definitely use Top Lock Locksmiths again.
