A master key system lets different keys open different combinations of doors: a manager's key opens everything, a staff key opens only the doors that person needs, and a cleaner's key opens only common areas. Combined with restricted keys, it gives a business real control over access and makes lost keys far less disruptive.
When to call us
- Managers carry large key rings.
- Staff have access to rooms they do not need.
- Losing one key would mean rekeying every door.
- Nobody knows exactly who holds which key.
How the job works
- We map every door and every role that needs access.
- We design the key hierarchy and document it in a key chart.
- Cylinders are pinned to the design and installed.
- Keys are stamped, issued and recorded.
- The chart and records are handed to the owner.
Designing a system that lasts
A master key system works by giving each cylinder more than one valid key combination. A staff key operates one combination, the master key another. Designing a good system means planning the hierarchy carefully, leaving room for future doors, and avoiding too many levels, which weakens security.
The key chart that records the design is valuable and should be kept confidential. With it, any cylinder can be rekeyed later without disturbing the rest of the system; without it, a building can end up with an unmanageable mix of keys.
What affects the price
The dispatcher explains the service call before anyone is sent, and the technician confirms the total with you before starting any work that adds cost. The main price drivers are:
- Number of doors and levels in the hierarchy.
- Standard or restricted keyway.
- Whether existing hardware can be reused.
- Number of keys issued.

Master Key Systems in Toronto: local context
Small offices, clinics and retail stores across Toronto often grow into a tangle of keys over the years. A master key system brings order, and a key chart means the next locksmith, or the next manager, knows exactly how it works.
