What is a master key system, and who needs one in Burbank?
A master key system lets one key open many locks while every individual lock still has its own key that opens only that lock. A property manager carries one key, each tenant carries one key, and the tenant's key does not open the neighbor's door. The result comes from how the cylinders are built and pinned on the inside. It is not a trick and it is not a shortcut. It is a planned design, and the plan matters more than any single part.
In Burbank, the people who call about this are fairly predictable. They are property managers with apartment buildings and condo complexes, owners of multi-tenant offices and small production spaces, retail owners who run more than one storefront, and medical or professional offices where staff need access to some rooms but not others. What they share is a key ring problem: too many keys, no clear record of who holds what, and a nagging worry that a former employee or tenant still has a working copy.
You will hear this service described several ways: a commercial master key system, a business master key system, an apartment master key system, a key control system, or an employee key control system. The engineering underneath is the same. What changes is the set of rules about who gets which level of access. If you run a business and want the wider picture of what we do on that side, our commercial locksmith service in Burbank page covers it.
How does a master key hierarchy work?
Every master key system is a hierarchy, a chart that says which keys open which doors. Before any cylinder is touched, that chart should exist on paper. The levels are simple to describe, even if the pinning behind them takes skill.
A small building might need only two levels. A larger one might need three or four. The right number is the smallest one that does the job, because every added level adds complexity and slightly increases the chance of unintended key combinations that open a lock they should not.
- Change key: opens one lock only. This is the tenant's, employee's, or room's own key.
- Master key: opens a defined group of locks, such as every office on one floor or every unit in one wing.
- Grand master key: opens several master groups, for example every floor of a building.
- Great grand master: a rarely used top level for large campuses or multi-building properties, held by very few people.
- Keyed-alike groups: a set of locks that all open with one shared key, often used for a main entrance and a side door that the same people use.

Call (213) 577-1366How do we design and install a master key system?
We do this in a set order, because skipping the planning stage is how systems end up with doors nobody can open or keys that open too much. David oversees the design on every system we take on.
- Walk the property. We look at every door, gate, cabinet, and storage room that might be part of the system, and note what hardware is already there and what shape it is in.
- Build the access chart together. You tell us who needs to get into what. We turn that into a hierarchy and flag any place where a requested setup would be awkward or weak.
- Choose the cylinders and keyway. We decide which existing locks can be reused, which need new cylinders or hardware, and whether a standard or restricted keyway fits your goals.
- Build and cut. The cylinders are pinned to match the chart and the keys are cut and labeled by level, not by guesswork.
- Install and test every door. Each key is tried in each lock it should open and in the locks it should not. A system is only finished when the failures have been tested for, not just the successes.
- Hand over the records. You receive the hierarchy chart, a key log to track who holds which key, and clear rules about how copies are ordered.
What is a restricted keyway, and what are duplicate-protected keys?
A restricted keyway is a key profile that the manufacturer controls. Blank keys for it are not sold over the counter, so a stranger cannot walk into a typical hardware store or kiosk and get a copy cut. Duplicate-protected keys go a step further: the key is stamped or registered, and new copies are released only to an authorized person who can show the right credentials or authorization.
For an employee key control system this is the difference between a policy and a real barrier. A sign saying do not duplicate stops no one. A restricted key system makes unauthorized copying inconvenient at the point where it would happen. If you only need ordinary copies of unrestricted keys, our key duplication service handles that, but restricted and protected keys follow different rules and we will explain them before you commit.
We want to be honest about the limits. A restricted keyway protects the key, not the door. A weak strike plate, a hollow frame, or an old latch can still be the easiest way in, so we look at the whole opening. Availability also varies by product line, and we confirm what is actually offered for your hardware before promising a particular setup. If your concern is broader than keys, the options in our high-security locks work are worth a look alongside the system.

Call (213) 577-1366What affects the cost of a master key system in Burbank?
We do not quote a figure over the phone for a system we have not seen, and no honest locksmith should. Systems vary too much. Here is what moves the cost up or down, so you can see why a walkthrough comes first.
- Number of locks. More cylinders means more parts, more pinning, and more testing time.
- Number of hierarchy levels. A two-level setup is simpler to build than one with grand masters and separate groups.
- Standard versus restricted keyway. Restricted and duplicate-protected key products generally carry a higher component cost than common keyways.
- Condition of existing hardware. Locks in good shape can often be rebuilt into the system. Worn, damaged, or mismatched locks may need replacement, which may also involve commercial door hardware.
- Number of keys. Every key cut and labeled adds to the job, and a larger staff or more tenants means more keys.
- Door condition. Doors that drag, sag, or swell can cause binding that gets blamed on the lock, and fixing the door may be part of the work.
- Added features. Pairing keys with electronic readers or other access hardware changes the scope entirely.
- Timing. After-hours or urgent scheduling can affect how a job is planned.
Can we rekey what we already have instead of replacing everything?
Often, yes, and that is usually the more economical route. If your existing cylinders are in good condition and compatible, they can be rebuilt into a master key system through a master key rekey rather than being thrown away. This is the same basic skill as a standard lock rekey, done with a more detailed plan behind it. We will tell you plainly which locks can be reused and which are not worth the effort.
How do master key systems fit Burbank buildings and neighborhoods?
Burbank is not one kind of place, and the right design depends on what the building is. We work from the data we have about the city, and from there we apply the system to the property in front of us.
Around the Media District, a common need is office and gate access hardware for media companies. A production office might have open work areas, locked equipment rooms, a storage cage, and a shared gate. A master key system with a restricted keyway lets the facilities lead open everything, gives each department only its own spaces, and keeps freelancers and short-term crew from walking away with a copy they can have cut anywhere.
Downtown Burbank and the area along the Chandler Bikeway have mid-rise condos and large controlled-access apartment complexes. Here an apartment master key system helps with the day-to-day problems: a manager who can open a unit after a tenant lockout without hunting for a separate key, and staff keys for trash rooms, mail areas, and utility closets that do not open any unit. For owners handling multiple units, our locksmith service for landlords page explains turnover and tenant rekeying in more detail.
Magnolia Park has 1920s to 1940s bungalows, and across Burbank many older homes still have original mid-century door hardware. Old hardware can be fussy. Worn cylinders, unusual backsets, and inconsistent parts do not always take a master pinning cleanly, so on older properties we inspect before promising the system will work on what is installed. Storefronts along Magnolia Boulevard and San Fernando Boulevard bring their own question: a shop owner with a front door, a back door, and a storage room usually wants a setup where staff keys open only what they need.
Climate plays a small part too. Valley summer heat swells wooden doors, and a swollen door can make a perfectly good lock feel stiff. Hillside homes above Glenoaks Boulevard see more sun and wind, and the Rancho District has equestrian-zoned lots where a main house and outbuildings could share a keyed plan. Burbank sits inland, so we do not worry about salt-air corrosion, but heat and dry wind still wear on exterior hardware over the years.
We work across Burbank's ZIP codes, 91501, 91502, 91504, 91505, and 91506. Our storefront is at 10740 Wilshire Blvd in Westwood, about 16 miles away, and our mobile vans bring the work to your door.

Call (213) 577-1366When is a master key system the wrong answer?
We would rather tell you than sell you something unsuitable. If you have one or two doors, a plain rekey does the job and a hierarchy is overkill. If you have heavy staff turnover and a large number of people to track, a physical master key system can become a burden, because every lost or unreturned key is a conversation about rekeying. In those cases, electronic access control installation may fit better, since a credential can be turned off without changing a lock.
There is also an honest trade-off in the design itself. A master key is powerful, which is the point and also the risk. If a master key is lost, every door it opens is affected, and the right response is usually a rekey of that group. We plan for that from the start, by limiting how many masters exist, keeping a record of who holds them, and organizing the system so that losing a low-level key does not become a building-wide problem.
Why call Wilshire Lock & Key for a master key system?
We have been in business since 1987, and master keying is a craft where experience shows. The things that cause trouble, such as unclear charts, unplanned key crossings, and doors that were never tested, are things we have learned to catch early.
We operate from a real storefront at 10740 Wilshire Blvd in Westwood, with mobile service vans for on-site work. We are one company. There is no dispatch middleman who hands your job to a stranger, so the person who plans your system is connected to the person who installs it. David, the owner and lead technician, oversees the design.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith, including us, for it before work begins. If your building is locked out right now and the problem is access rather than a system, see our business lockout service. For anything else, call (213) 577-1366. The line is answered 24 hours a day, 7 days a week.
Frequently asked questions
How much does a master key system cost in Burbank?
It depends on the number of locks, the number of hierarchy levels, whether you choose a restricted keyway, the condition of your existing hardware, and how many keys you need. We price after seeing the doors, because a quote made blind is a guess. Reusing compatible locks is usually the more economical route.
Can you add a master key to the locks we already have?
Often, yes. If the existing cylinders are in good shape and compatible, they can be rebuilt into the system. Worn, damaged, or mismatched locks may need replacement. We check each one in person before saying which route applies.
What is a restricted keyway and do I need one?
A restricted keyway is a key profile whose blanks are controlled by the manufacturer, so copies are not freely available. You need one if you want real control over who can duplicate keys, such as with employees, contractors, or tenants. For a small, low-risk setup, a standard keyway may be enough.
What happens if a master key is lost?
Because a master key opens a whole group of locks, we treat a loss seriously. The usual fix is rekeying the affected group so the lost key no longer works. That is why we limit how many masters exist and keep a key log from the start.
Can an apartment building use a master key system?
Yes. An apartment master key system gives the manager access to units and gives staff keys for common areas, while each tenant's key opens only their own door. Between tenants, individual units can be rekeyed without rebuilding the whole system.
How is a master key system different from keyed-alike locks?
Keyed-alike locks all open with the same single key. A master key system gives each lock its own key and adds higher-level keys that open groups of locks. Keyed-alike is simpler, but it provides no separation between people.
Can I get extra copies of duplicate-protected keys?
Yes, but only through authorization. Protected keys are released to people the owner has approved, not to anyone who walks in. That control is the whole point, and we explain the process during setup so you know who can order copies.
Do you work on master key systems at night or on weekends in Burbank?
Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round. Design and installation work is scheduled around your property, and we will talk through timing when you call.
