A master key system lets one key open every door a manager needs while each engineer, tenant or shift lead carries a key that opens only what belongs to them. Santa Clara runs a great many of them: a lab off Lawrence Expressway with shared instruments and a locked chemical store, a startup that sublets half a floor near Scott Blvd, a small office building on El Camino with six tenants, a server room that has to sit under a different key from the rest of the suite. Wafer Lock & Key designs the system, pins it, and hands over the paperwork that lets you run it without calling anyone.
It begins as a chart. From a floor plan or a walk-through, and a frank conversation about who goes where and who must not, the technician draws the levels: a grand master if a portfolio needs one, a master per building or floor, sub-masters by department, change keys at each door. A restricted keyway goes underneath the whole thing so a hardware counter cannot cut copies, which is how one change key quietly becomes three. Cylinders are pinned in the van with master pins stacked over the change pins, every key is stamped with its level and logged by number, and you get the chart back showing which key opens which door. Blank rows are left in it so next year's doors join the same system instead of starting a second.
Master key work is quoted per project, because door count, keyway and restricted-key options set the price, and a single published figure would be a guess. The written quote lists cylinders by door, keys by level, and design time once. The $89 visit covers the survey and is counted toward the job. Once you approve the quote it does not move. Repinning one door later stays inside the system at the $24 to $39 per-cylinder figure.
Describe: the door count and the kind of building. Agree: the chart and the itemized quote arrive in writing after the survey, and installation is booked once you approve. Fit: each cylinder pinned and tested in its own door, keys handed over logged and signed for, receipt itemized cylinder by cylinder.
“Townhome off Rivermark Plaza, door pulled shut behind me with the keys and the baby monitor both inside. Quoted $149 on the call, text with the technician's name two minutes later, van in eighteen. He picked the deadbolt in about three minutes and the keypad on the garage stayed exactly as it was. $149 on the card and the receipt in my inbox before I had the stroller back in.”

FAQ
Master Key Systems: quick answers
We are a forty-person startup with a lab, a server room and a shared floor. What does the system look like?+
Three levels. Staff carry a change key for the shared floor. Lab staff carry a key that also opens the lab. The server room sits on its own sub-master held by two people. The office manager holds the master. When someone leaves, only the doors their key opened are repinned, which is usually one.
Do our existing cylinders have to be replaced?+
Most of the time. Commercial cylinders from the major makers accept master pinning. A cylinder in a keyway that cannot join, or one so worn that an extra pin stack would jam, is swapped and shown as a line in the quote, so the count is visible before work begins.
What if the master key is lost?+
The doors under that master are repinned, and only those. That is the practical argument for levels instead of one master over everything. With a restricted keyway, an unauthorized copy is unlikely to exist in the first place.
