Master key system design
A hierarchy built from your actual door list: who needs which door, which doors must stay separate, and where a lost key should stop mattering.
One key, controlled access
Master Key Systems in Strongsville, Ohio
A documented key hierarchy for homes, rentals and businesses — one master, the right levels, no stray copies.
The work
Master key system design, keyed-alike conversion, restricted keyways and written key schedules for homes, landlords and commercial buildings.
A master key system is one of the few lock jobs that pays for itself twice. It removes the daily friction of a building where every door needs a different key, and it means a staff departure or a lost set costs you one key rather than a rekey of the whole property.
The work starts with a list, not a lock. Every door is recorded with its function, who genuinely needs through it, and whether it sits on an escape route. From that list a hierarchy is designed — individual keys, staff or family keys, a supervisor level and a single master above them all.
Existing cylinders are rekeyed into the system wherever the hardware is sound, so most projects are a rekey rather than a full replacement. You leave with the new keys, a written schedule showing who holds what, and cylinders that can be extended later without starting again.
What we handle
Every job that falls under this service
If it involves a lock, a key, a cylinder or a door that has stopped doing its job, it belongs on this list.
Keyed-alike conversion
Every lock you nominate pinned to a single key — front door, back door, garage, gate and outbuilding on one key instead of five.
Rekeying into a new system
Existing cylinders are rekeyed rather than replaced wherever they are in good condition, which keeps the cost of a full building change realistic.
Restricted and high-security keyways
Blanks that cannot be copied at a hardware store, with duplication only on your authorisation — the cleanest end to uncontrolled key copying.
Written key schedule
A documented record of every level, every cylinder and every key issued, so a future rekey touches one level instead of the entire property.
Expansion and rekeying later
New doors, new staff and lost keys are mapped into the existing hierarchy. Capacity is designed in from the start so it does not need rebuilding.
Included as standard

How a call runs
From request to a tested lock
Four steps, in this order, every time.
List the doors
Tell us how many doors there are, which building or units they serve, and who needs access to what. A photo of each door is plenty.
Design the levels
We map individual, staff, supervisor and master keys to the doors they should operate and confirm the plan with you before any cylinder is touched.
Rekey and cut
Cylinders are rekeyed or replaced on site and every key is cut, tested against its doors and labelled by level.
Document and hand over
You receive the keys, the written schedule and a note of which cylinders were rekeyed, so the system stays understandable a year later.
