Master Key Systems

What Is a Master Key System?
A master key system allows access to multiple doors or locks within a building using a single master key.

The key can be cut, like the master key for an apartment complex, or digital, like a magnetic card, fob, or code entry.

The system can include sub-master keys for access to specific areas or groups of locks.

An office building may have multiple rooms, offices, and corridors. A master key system can grant access to all areas for a single user, or it can be configured so that each area has its own sub-master key.

Who Uses Master Key Systems?

  • Apartment complexes
  • Schools
  • Hospitals
  • Government buildings
  • Corporate offices
  • Factories
  • Warehouses
  • Retail shopping spaces

Master key systems offer a balance between security and convenience. They provide secure access control while allowing authorized personnel to move freely around a building or complex.

If a lock needs changing or repair, there’s no need to replace all keys or locks in the system. It’s simply a matter of replacing or re-programming the sub-master key for that particular door or room.

Benefits of a Master Key System

  • Enhanced security: A master key system controls access to sensitive areas. Businesses can protect valuable assets and confidential information from unauthorized access.
  • Convenience: Authorized personnel no longer need to carry multiple keys for different building areas. This saves time, increases productivity, and reduces the risk of lost or stolen keys.
  • Easy access management: A master system is especially convenient when keys need to be replaced, or access needs to be granted or revoked.
  • Affordability: Master key systems are more cost-effective than traditional lock and key methods because they require fewer keys. Businesses can implement an access control system without a significant investment in new locks or hardware.

Types of Master Key Systems We Install

  • Digital: A digital master key system uses magnetic cards, fobs, or codes to grant access. It’s ideal for businesses that need to restrict access to sensitive areas and monitor who enters them.
  • Mechanical: Mechanical systems use physical keys cut in different patterns. This is the traditional master key system many apartment buildings and schools use.

Choosing the Right Master Key System

Factors to consider include building size, the level of security you need, and the number of locks required.

  • Pin-tumbler systems are more secure and are best for buildings with a large number of locks.
  • Magnetic systems are cheaper but can be vulnerable to tampering.
  • Wafer-tumbler systems offer a good balance between security and affordability.
  • Some systems allow complete control over key duplication. Others may require authorization.
  • Choosing a master key system compatible with your existing locks and hardware will save time, money, and installation costs.
  • Some systems record transactions, so you can track who accessed which areas and when.
