Master key systems in Provo let a manager carry one key to every door while each employee or tenant carries a key to only their own space. We plan the hierarchy with you, pin every cylinder to a written keying schedule, and can put the top keys on a restricted keyway so they cannot be copied at a hardware store kiosk.
In a master keyed cylinder, some pin stacks get an extra thin pin called a master pin. It gives the stack two places to split at the shear line, so two different keys can turn the same lock: the door's own key and the key above it. Systems are built in levels:
The need usually shows up on the key ring first. Consider a system when:

Call (801) 555-0142More levels add convenience, but each level up also opens more cylinders if that key goes missing. Pick the simplest structure that fits how the building is used.
| Structure | How it works | Good fit | If the top key is lost |
|---|---|---|---|
| Keyed different | Each lock has its own key | A few doors, few people | Only that one lock is exposed |
| Keyed alike | Several locks share one key | Exterior doors of a small shop | Every door on that key |
| Two-level master | Change keys plus one master | One office, clinic, or apartment building | Every cylinder in the building |
| Grand master | Several master groups under one top key | Multi-floor offices, churches, multi-building sites | Every cylinder in every group |
Each master pin also adds another way for a pin stack to line up, so more key combinations will turn the cylinder and a skilled attacker has more to work with. That is why top-level keys belong on a restricted or high-security keyway and in as few hands as possible.

A master key system is priced from the keying schedule, so the plan comes before the number. The factors:
Buildings vary too much for a single national price to be useful. We give you the exact price on the phone once we know the door count, brands, and levels, and confirm it on site before a cylinder comes out.
Provo suits master keying because so much of the city is shared housing. American Community Survey data counts about 40,000 undergraduates living in Provo, and buildings full of student tenants are where per-unit keys and one manager's key pay off. When a tenant moves out, their cylinder can be repinned to an unused change key while the manager's master keeps working.
Offices and churches use the hierarchy differently. A multi-building office campus like the Riverwoods Business Park, or a meetinghouse with classrooms, offices, and a kitchen, can justify a grand master level. A single office suite near Center Street usually needs only two levels. For the busiest lobby doors, consider adding card or fob access control and keeping keys for interior rooms.
Why Choose Us
1 schedule
A master key system is only as good as its records. We leave you a keying schedule that lists every door, its key symbol, and the keys that operate it, plus a key log for tracking who holds each stamped key. When a hire starts or a tenant leaves, you can see in a minute which cylinder needs attention instead of guessing from a drawer of loose keys.
2-way test
Confirming that each key works is only half the test. We also try every key in doors outside its group, because a key that quietly opens the wrong office is a security hole nobody notices in daily use. Catching that during installation takes minutes. Finding it after something goes missing from a locked room costs far more, in money and in trust.
24/7
A lost master key is the one emergency a master system creates. We answer around the clock, help you work out which cylinders that key can open, and start repinning them to a new master once you approve. Exterior doors and rooms holding cash, records, or medication go first, which limits exposure while the rest of the building is finished.
Our Promise
Locksmithing runs on trust. These are the commitments you can hold us to on every call, from a 2 a.m. lockout to a full office rekey.
We quote on the phone, then confirm the total on site before any work begins. If the job turns out to be different than described, you approve the new number before we continue.
We confirm you live at the address or own the vehicle before we open anything. It takes about a minute, and it is the same check that protects your home from someone else claiming to be you.
We pick, bypass, or decode before we ever consider drilling. If a lock truly has to be drilled, we explain why and get your OK first, and we can replace it on the spot.
Nights, weekends, and holidays use the same phone number. You get a person, a price, and an arrival estimate, not a voicemail box.
FAQ
Often. If your cylinders share a brand and keyway and are in good shape, they can usually be repinned into a master system. Mixed brands, worn cylinders, and bargain hardware may need replacing first. We tell you which doors qualify once we count the cylinders.
Every cylinder that master opens should be repinned to a new master, or you accept the risk. That is the main cost of master keying, and it grows with each level. Restricted keyways, few master holders, and a signed key log make it less likely.
Somewhat. Master pins add extra points where a pin stack can line up, so more key combinations turn the cylinder and a picker has more chances. Careful system design keeps those extra combinations to a minimum, and high-security cylinders add pick resistance on the doors that matter most.
Not reliably. The stamp is only a request, and many kiosks will cut the key anyway. Real key control comes from a restricted keyway, where blanks are sold only through authorized dealers and copies require approval from the person named on the account.
Not in a properly designed system. Each unit gets its own change key, and only the master or grand master opens more than one unit. Trouble comes from systems expanded for years without a schedule, which can create keys that open the wrong doors.
