Too Many Keys at Your Jacksonville Business? A Master Key System That Fits Your Team

How a master key system works

Think of the keys as a pyramid.

• Change keys open a single door or lock, such as one office, one apartment or one storage room.
• Sub-master keys open a group of doors, such as one floor, one department or one building wing.
• Master keys open every lock in the system.
• Grand master keys sit above several masters, for owners with more than one building or property.

Here's a simple example. At a medical office, the front desk key opens the lobby and reception. Each provider's key opens their exam rooms. The office manager's key opens every office, and the owner's master opens everything, including the records room and the server closet. The cleaning crew's key opens only the common areas.

Who uses master key systems

• Offices and professional suites where staff, managers and cleaners need different access
• Medical and dental offices with records rooms and medicine storage
• Churches with offices, classrooms, kitchens and sanctuaries
• Landlords and property managers with many units and one set of keys to carry. See our page for property managers and realtors.
• HOA clubhouses, pool gates and maintenance rooms
• Warehouses and shops with offices, cages and loading docks

Signs it's time for a master key system

• Managers carry a ring of ten or more keys and still can't open every door.
• Nobody is sure how many copies of the front door key exist.
• Keys are labeled with room names on a hook in the break room.
• Every time someone leaves, you rekey everything or, worse, nothing.
• New tenants, staff or vendors need access to some doors but not others.

How we set one up

1. Walk-through. We visit, list every door and lock, and check which hardware can be rekeyed.
2. Keying plan. We work out who needs to open what. That becomes a keying schedule: a written list of each key and the doors it opens.
3. Key chart. We calculate the pin depths for each level. The chart stays with you and with us, and it isn't shared with anyone else.
4. Keying the locks. We rekey your existing cylinders into the system, or install new ones where needed. We work door by door so the building is never left open.
5. Cutting and labeling keys. Each key gets a stamped code instead of a room name, so a lost key doesn't tell a stranger which door it opens.
6. Testing and handover. We test every key in every lock, then hand you the schedule and a simple key log.

Our lock installations are backed by a 5-year money-back guarantee.

Key control: who can copy your keys?

A master key system is only as good as your control of the keys. Be clear about one thing: a key stamped "Do Not Duplicate" is a request, not a lock on copying. Many shops will copy it anyway.

For real key control, we recommend a restricted or patented keyway for the master level. Keys for systems like Medeco and Mul-T-Lock use blanks that aren't sold to the public, and copies are only cut for people on your authorized list. This matters most for businesses with staff turnover, and for landlords who hand keys to tenants and vendors.

Plan it right: the trade-offs

A master key system adds convenience, but every level adds risk if a key goes missing. We help you keep it simple:

• Make very few top-level masters. Two or three are usually enough.
• Use the fewest levels that work. More levels mean more combinations inside each lock and more to manage.
• Leave room to grow. A good chart has space for new doors and new tenants without rekeying everything.
• Keep a key log. Track who holds each key, and collect keys when people leave.

If a key is lost, we rekey only the part of the system that key opens. That's the payoff for planning.

Working with your existing locks

Many Jacksonville offices and shopping centers have a mix of locks installed by past tenants over the years. Common commercial brands such as Schlage, Yale, Sargent, Medeco and Mul-T-Lock can be keyed into a system. Mixed brands can sometimes share a keyway with new cylinders, while worn or low-grade locks are better replaced. See lock installation for new hardware.

What a master key system costs

Every system is different, so we quote after a walk-through. The price depends on:

• The number of doors and cylinders, including padlocks, cabinets and gates
• The number of levels in the system
• Rekeying or new cylinders. Rekeying existing compatible locks costs far less.
• Standard or restricted keyways. Restricted keys cost more but give real key control.
• How many keys you need cut

See our pricing guide for more. You get the full price on the phone before we drive out, and we confirm it before any work starts.
