High Security Locks

Open 24/7

You run a home office with client files and equipment, and your insurer has asked what kind of lock is on the door. The honest answer is the builder's knob lock and a light deadbolt from when the house was new.

In plain words

High security locks are cylinders and deadbolts designed to defeat the methods used against ordinary doors. Inside the cylinder a second locking mechanism, usually a sidebar released by finger pins or rotating pins, has to be satisfied at the same time as the normal pin stack, which is what stops picking and bumping. Hardened steel inserts stop drill bits. The bolt is thicker and carries a hardened pin against sawing, and a reinforced strike ties the lock into the wall framing. Just as important, the key is cut on a patented blank that only an authorised person can have copied, so your key count stays known.

The call: 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.

How the visit goes

Scene 1
Door, hinges and what surrounds them
The door itself is inspected as part of the lock. Hollow-core doors, thin panels beside the lock, and hinge screws that barely bite into the frame all undo the value of a strong cylinder. The locksmith checks how the door hangs, whether it drags or needs a shoulder to close, and whether the hinges are on the secure side. Glass close to the lock is noted, because a hand through a broken sidelight can reach an inside thumb-turn. None of this rules out an upgrade; it shows which supporting pieces belong in the plan so the whole opening is brought up together.
Scene 2
Keying several doors sensibly
When more than one door is upgraded, the locksmith plans the keying before pinning anything. A home usually wants every exterior door on one key. A business often wants staff keys that open the front and their own area, and one manager key that opens everything, arranged as a small master system on the same patented keyway. Cylinders are pinned on the bench, labelled and fitted door by door, and each key is checked against the doors it should open and, just as carefully, the doors it should not. The written key schedule is part of the handover.
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 quoteDrummond Heights Locksmith Co.

Exit devices and closers on the same door: Where a commercial door carries a push bar or closer, the new lock must work with them, and adjusting or replacing that hardware is part of the same visit.
Retiring the old keyway: If other doors stay on the old key for now, they may need rekeying so an unknown copy has nowhere to go; that is additional cylinder work alongside the upgrade.
Cylinder rating and format: A patented residential cylinder, a laboratory-rated commercial cylinder and an interchangeable core sit at different points on the scale, and the format that fits your present hardware decides which lines are available.

Short answers to common questions

Do I need to replace my whole deadbolt or just the cylinder?

It depends on what you have. If the deadbolt is a good heavy unit that throws a full inch into a proper strike, a high security cylinder can replace the ordinary one and the rest stays. If the deadbolt is light, worn or throws a short bolt, a new graded deadbolt with a hardened bolt is the sensible base and the high security cylinder goes into that. The assessment tells you which, door by door.

Are high security locks only for businesses?

Not at all. Homes are the most common place they are fitted, especially after a move, a break-in nearby, or the realisation that too many keys have been handed out over the years. A graded deadbolt with a patented cylinder and a reinforced strike is a modest, quiet upgrade for a front or side door. Businesses tend to go further, with laboratory-rated cylinders, heavy lock bodies and a documented key system across many doors.

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.
