A school wants six more doors on a system from years ago
The business manager rings. The school has a new block and wants the doors on the existing master key system. Your firm installed it, you are sure of that. The original chart was produced by the cylinder manufacturer, printed and filed. Since then there have been two extensions, a batch of replacement keys, a cylinder swapped after a break-in and a handful of doors that were rekeyed when a department moved.
Some of that is in the paper file. Some is in emails with the manufacturer. Some is in an engineer's notebook. The school has its own key register, which disagrees with yours in at least three places. Before you can quote the extension, someone has to spend a day rebuilding what the system actually is.
Master key systems change and the records don't follow
A master key system is not a one-off job. It grows and changes for as long as the building is in use. The original design is usually well documented because the manufacturer produces it. Everything that happens afterwards is recorded in whatever was to hand at the time.
- The original chart is a PDF or a printout, not a record you can update.
- Extensions and changes are ordered from the manufacturer by email and only the confirmation is filed.
- Key issues are recorded by the client, if at all, not by you.
- Door names drift: "Room 12" becomes "Art 2" after a refurbishment, and the chart never catches up.
- The engineer who designed the system has retired or moved on.
None of this is about the design of the system itself. It is about the admin that sits around it.
Slow quotes, wrong orders, awkward conversations
An extension quoted from an out-of-date chart risks cylinders being ordered on the wrong key level, which means reorders, delays and a client who starts wondering whether you still know their building. Replacement key orders take longer than they should because the office has to check authorisation and codes by hand.
These are some of the longest-running relationships a locksmith has. Commercial sites with master key systems come back for years. Losing track of the record is how that relationship becomes vulnerable to another firm.
One living record per master key system
We build a master key system register for your business. It is not a replacement for the manufacturer's own system design tools; it is the place where your firm's knowledge of each client's system lives.
- Each system has a record: site, client contacts, manufacturer, system reference and the authorised people who can order keys or changes.
- The chart is held as structured data (keys, levels, doors) rather than only as a PDF, imported from the manufacturer's export where one exists.
- Doors carry their current name and every previous name, so an old reference still finds the right door.
- Every change is logged as an event: extension, rekey, replacement cylinder, extra keys cut, with the date, the engineer and the order reference.
- Key issues can be recorded if the client wants you to hold that register, or linked to theirs if they keep it.
- Replacement key requests are checked against the list of authorised people before the order goes to the manufacturer.
- Access to the register is restricted by role and logged, because these records are sensitive for your clients.
| Question | Before | After |
|---|---|---|
| What doors are on this system? | Rebuilt from a printout and emails | Current list in the record |
| Who is allowed to order keys? | Checked by phone or memory | Authorised list checked automatically |
| What changed since installation? | Scattered across notes and emails | Dated change history |
| Can we quote the extension? | After a day of research | From the current chart |
We work with the manufacturer's processes rather than around them. Where a manufacturer controls key and cylinder orders through its own portal and authorisation cards, the register records the references and keeps your own view in step.
Extensions and key orders start from facts
When the business manager rings about the new block, the office opens the system, sees every door and change, and can pass accurate information to the manufacturer for the extension design. When a replacement key request arrives, the authorised list is right there. When an engineer leaves, their knowledge of the client's system does not leave with them.
It also becomes something you can show a client: a tidy summary of their system and its history, which is a good reason for them to keep coming back to you.
Is your master key admin like this?
- Charts for older systems exist only as printouts or PDFs.
- You rely on the client's key register rather than your own records.
- Quoting an extension means searching old emails first.
- Only one person in the firm really knows your larger systems.
- Door names on your charts no longer match the building.
