High Security Locks

Open 24/7

After the attempted break-in the police officer pointed at your door and said the strike plate was held by two short screws. Nobody got in, but you have looked at that door differently every evening since.

In plain words

For a business, high security locks are as much about paperwork as metal. A restricted or patented key system registers the premises with the locksmith, names who may order keys, and numbers every key cut. That is what turns a lost staff key from a mystery into a line in a log. The hardware backs it up: cylinders with sidebars and hardened inserts, heavy-duty deadbolts or mortise locks, and strikes set into the structure. Where several doors are involved the keys can be arranged so a manager carries one key and staff carry keys that open only their own areas.

The call: 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.

How the visit goes

Scene 1
The bolt, the pocket and the strike
A deadbolt is only as good as how far it reaches and what it reaches into. The locksmith measures the throw of the bolt with the door closed, checks that it fully extends without the door being lifted or pushed, and looks at the pocket it enters in the jamb. A shallow pocket, a stamped strike plate and screws barely longer than a thumbnail are the usual finding on a builder-grade door. Then the frame is examined for splits, soft wood and gaps behind the jamb, since a kick lands on the strike, not on the cylinder.
Scene 2
Setting up controlled keys
The key system is registered to you before the first key is cut. The locksmith records the system, the authorised signatories and the number of keys issued, and hands you the authorisation card or online validation details. Every key is cut from code rather than copied, because the angled cuts or side milling must be exact for the sidebar to release. Extra keys later are ordered by an authorised person and logged, and blanks are not sold outside the manufacturer's network. This is what makes a key stop being a thing anyone can duplicate at a kiosk.
Scene 3
Watching the patent calendar
Patented keyways protect you for as long as the patent lasts. When it expires, blanks may be sold openly and the copy-control layer weakens, though the mechanical resistance of the cylinder stays. The locksmith notes the patent term of your system at handover so the date is not a surprise. Many years before it arrives, the same hardware can usually be moved to a newer patented keyway by changing cylinders and keys while the lock bodies stay. Treat it like a roof: nothing needs doing for a long while, but the date is written down.

What shapes the quoteBell Ewart Lock Services

Glass near the lock: Sidelights or glazed panels beside the deadbolt may call for a different function or extra hardware to keep the inside turn out of reach, always keeping easy exit in view.
Number of keys cut: Every key is cut from code on a machine that handles side bitting or angled cuts, so the count of keys you want at handover is a real line rather than a rounding error.
Number of doors: Each door gets its own cylinder or lock, strike work and testing. Several doors on one keyway share the setup cost of the key system but add hardware and time per opening.

Is a high security cylinder really pick proof?

Nothing is beyond a laboratory with unlimited time, so the honest measure is minutes, not absolutes. Rated cylinders are tested to resist skilled picking and impressioning for a set period, and drilling and forcing for another. In the real world that matters because someone at a door has seconds, not a workbench. The sidebar and false grooves in the pins give a picker nothing reliable to feel, and the hardened inserts stop a bit, which is why these attacks move on to easier doors.

What should I do when a controlled key is lost?

Tell your locksmith so the register is updated, then decide together what the loss means. If the key was lost with nothing identifying your address, the practical risk is low and many people simply strike it off. If it went missing with identification or from a known person, the affected cylinders can be repinned so that key stops working while the rest of the system continues. Because the keyway is controlled, you know that no further copies exist.

What are the hardware grades I see on the packaging?

Locks and deadbolts are tested against industry standards for security, durability and finish. Commercial hardware is graded 1, 2 or 3 with grade 1 the highest. Residential hardware carries a letter label for each of the three categories, from C for good through B to A for the top level. Security tests include hammer blows and pulling on the lock; durability covers cycle life and seasonal misalignment; finish covers salt, humidity and scratching. Your locksmith translates the label for your door.
