A master system is a planned hierarchy. At the top, a master key opens everything; below it, keys open only their assigned doors. The planning — the key chart — matters as much as the pinning, because a sloppy chart creates keys that accidentally cross.
Systems drift without records. We document the chart so the next rekey, the next new door, and the next role change extend the system cleanly instead of breaking it.
How a master system is built
Setting up a master system in the San Fernando Valley:
- We confirm your authority over the premises and check ID.
- We map who needs access to what and design the key chart around it.
- We pin each cylinder to the chart and cut the master, sub-master, and change keys.
- We hand over documentation and the total agreed in writing before the work began.
- We test each door against the chart so every key opens exactly what it should.
- We build in room to grow, so adding a door later does not force a redesign.
When you need this
- Different roles need different access across several doors.
- You are tired of issuing full key sets to everyone.
- A growing business needs access it can scope and track.
- An existing master system has drifted and needs reorganizing.
Honest limits
Existing cylinders do not all support clean master pinning. Where hardware will not hold a reliable chart, we are upfront that some cylinders need changing first rather than forcing a system that cross-keys by accident.
What affects what you pay
Rather than guess at a price online, we look at the lock or vehicle, explain your options, and give you the total up front. You approve it in writing before we start.
The main cost factors are the hardware involved, how the job has to be done, the time of day, and whether parts need ordering in. We walk through those with you on the call so the written quote holds no surprises.
How we keep it honest
Expect us to ask for identification and some proof that the property or vehicle is yours or that you are authorized for it. We do this on every job, and we appreciate your patience with it.
Our arrival estimate is tied to our actual location and the roads that day. If something changes it, we tell you instead of leaving you guessing.

Questions people ask
What is the difference between a master and a change key?
A change key opens one door; a master opens a defined group. In a well-planned the San Fernando Valley system, each person carries the lowest-level key their role needs, and only managers hold the master.
Can you add a master system to our existing locks?
Often, if the cylinders accept master pinning. Where hardware will not support a clean chart, we will tell you which cylinders need changing first.
How do you stop staff copying the master?
With restricted or patented keyways that hardware stores cannot duplicate. We will recommend them where key control actually matters to you.
Will you document the system?
Yes. You get the key chart and records, so future rekeys and new doors extend the system consistently instead of breaking it.
Can the system grow as we add doors?
Yes, if it is planned that way. We design with room to expand so adding a door later does not force a redesign.
