High Security Locks

Open 24/7

The restricted keys you bought years ago are no longer restricted; the locksmith mentioned the patent has run out and blanks are sold openly. Your key control quietly stopped being control.

In plain words

Upgrading to high security rarely means new doors or a big disruption. Many high security cylinders retrofit into the existing deadbolt or lever, so the door preparation stays as it is and only the cylinder and keys change. A heavier deadbolt uses the same bore as the old one in most cases. The strike and hinge screws are swapped for long ones that bite into the framing. The visible difference afterwards is small; the practical difference is that the door resists the tools and tricks that defeat ordinary hardware, and that nobody can copy your key without you knowing.

The call: You jiggle the key a little and the old deadbolt opens even when the cut does not look quite right. If your worn key can do that, you wonder what a stranger with the right tools could do.

Scene 1
Who holds keys and who should
For a business or a rental, the locksmith asks to see the key list, or helps you start one. Which keys exist, who carries them, which doors they open, and what happens when someone leaves. This is where the case for a patented or restricted key system becomes clear, because the system replaces guesswork with a register: every key numbered, every order authorised by a named person, and no blanks available outside the locksmith who manages it. The locksmith also asks how many people need to reach each area so the keying plan reflects the way the building actually runs.
Scene 2
Heavy hardware for commercial doors
Storefront, warehouse and office doors take heavy-duty lock bodies rather than residential deadbolts. Depending on the door, that means a commercial deadbolt or mortise lock with a hardened cylinder guard, a free-spinning collar that defeats wrenches, and a laboratory-rated cylinder inside it. Narrow aluminium doors get a deadlock made for their stile. The locksmith fits the lock to the existing preparation where it is standard, adjusts the strike in the frame, and confirms that any exit device or closer on the same door still works exactly as before so people leave easily while the door holds from outside.
Scene 3
Proof for insurers, landlords and tenants
You leave with a written record of what was fitted: the cylinder type and its rating, the deadbolt grade, the strike and screws installed, and the key system registration. Insurers sometimes ask for this when a policy specifies stronger hardware, landlords keep it in the property file, and tenants have something to hand back at move-out. It also helps the next locksmith, who can see at a glance what keyway and format the doors carry. Keep the invoice and the key control documents together; they are the paperwork side of a physical upgrade.

What shapes the quoteJarvis Lock & Key Specialists

Key control level: A patented keyway with authorisation cards covers most homes. Geographically exclusive keyways and signature-controlled systems for businesses carry registration and administration that show in the quote.
Master keying: Arranging staff keys, area keys and a manager key on one system takes bench time to plan and pin, and the more levels you want, the more careful that planning is.
Commercial lock bodies: Heavy-duty deadbolts, mortise locks, narrow-stile deadlocks and cylinder guards for storefront and warehouse doors are heavier hardware than residential deadbolts and priced as such.

Asked and answered

Do high security locks need special maintenance?

Only light care. Use the dry lubricant the locksmith recommends once or twice a year, never oil, which gathers grit around the finger pins and sidebar. Keep the keyway free of debris and insert the key fully before turning. In winter, warm a resisting key in your hand or use a de-icer rather than forcing it. Check hinge and strike screws each season so the door stays aligned. Treated this way the cylinder lasts for decades.

Can all my doors be on one key?

Yes, and most homes ask for exactly that. Every exterior cylinder is pinned to the same combination so one controlled key opens the front, back, side and garage entry. A gate or shed padlock on the same keyway can join it. For businesses, the same keyway can carry a small master system where staff keys open only their areas and a manager key opens everything. The keying plan is agreed before any pinning is done.

How do I order extra keys later?

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do.
