Restricted Key Systems | Carbine Sigma X 🔑

Carbine Sigma X restricted key systems utilize patented key profiles designed to prevent unauthorized duplication. Copies can only be cut by the original locksmith or authorized personnel, ensuring strict control over access to your premises.

These systems are ideal for businesses requiring high security, multiple access levels, and tight key control. Featuring computer-generated, patented designs, protect the system from potentially unauthorised copying—providing superior protection for your assets and peace of mind.

Master Key System Design and Implementation

A master key system creates a structured hierarchy of keys, allowing a single master key to open all locks while individual or sub-master keys provide restricted access to designated areas. This approach simplifies key management for buildings with multiple departments or access requirements, delivering both convenience and security.

Our experts design custom master key systems tailored to your needs—balancing accessibility with strict access control. From simple master key setups to complex great-grand master key hierarchies for large-scale facilities, we ensure a secure and efficient solution for commercial, industrial, and residential properties.

High-Security & SCEC Approved Products

We recommend high-security systems that comply with stringent standards, including SCEC (Security Construction and Equipment Committee) approvals. Using SCEC-approved products guarantees your security solution meets government and regulatory requirements and provides robust protection against sophisticated attacks, making them ideal for high-risk environments and critical infrastructure.

Access Control Systems & RFID Key Card or Fob Replacement

Modern security solutions go beyond mechanical keys with electronic access control systems that provide trackable and controlled entry. These systems utilize RFID key cards and fobs, making them ideal for commercial properties requiring advanced security and user management.

TRS Locksmith Services also offers RFID card and fob replacement for lost or damaged credentials, ensuring uninterrupted access and security. For complete convenience, these electronic systems can be integrated with master key systems, delivering seamless overall control for your premises.
