Keyed-Alike Services
One key opens everything. If you want the ultimate convenience for your home or small business, our Keyed-Alike service is the perfect fit. Instead of carrying separate keys for your front door, back door, garage, and deadbolts, we rekey all your cylinders to work with one single key.
- Best For: Residential homes, small retail shops, and detached garages.
- Benefits: Lightens your keychain, saves time, and reduces the cost of duplicate keys.
Master-Keying Services
Controlled access, simplified. For properties where different people need different levels of access, our Master-Keying solutions offer smart, structured security. A master-key system allows designated individuals (like managers or owners) to access every lock, while restricting employees or tenants to specific doors only.
- Best For: Apartment buildings, office complexes, schools, and commercial facilities.
- Benefits: Enhances internal security, provides quick emergency access, and eliminates the need for massive master rings.
Master-Keyed Hierarchy Schematic
A master-key system uses a top-down logical structure. Below is a visual breakdown of a standard three-level hierarchy system (commonly used in corporate offices or apartment complexes):
How the Hierarchy Works:
- Great Grand Master Key: Typically held by the property owner, CEO, or head of security for universal emergency access.
- Grand Master Keys: Divided by major sectors, such as different physical buildings or entire departments.
- Master Keys: Issued to department heads or floor managers. For example, the Master A1 key opens all doors inside Accounting, but cannot open any doors in HR.
- Change Keys (User Level): Issued to individual employees or tenants. These keys only open one specific door (like an individual office or apartment) and nothing else.
