High Security Locks

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

Most break-ins do not involve picking; they involve a boot, a pry bar or a key that should never have been copied. High security hardware answers all three. A deadbolt with a full one-inch throw and a hardened core resists sawing and kicking, a reinforced strike with three-inch screws keeps the jamb whole, and a patented keyway means a copy can only be made through the locksmith who holds your system. The pick, bump and drill resistance of the cylinder is the layer on top. The locksmith's job is to fit those layers to your particular door and your particular worries.

Sound familiar?

You have lost count of how many people have had a key to your house over the years: cleaners, a contractor, a former partner, the previous owner's family. The lock still works, but you no longer know who else it works for.

How the visit goes

How the visit goes

  1. 1

    The fit of new hardware to old doors

    Older houses in this region have doors that predate modern hardware: narrower stiles, a mortise pocket already cut, a thick slab door or a steel-clad door with a specific backset. The locksmith measures the bore, backset, door thickness and edge preparation so the chosen deadbolt or cylinder fits without hacking at the door. Where a mortise lock is present, a high-security mortise cylinder often replaces the old one directly. Where a knob lock is the only lock, the assessment includes where a new deadbolt bore would sit and whether the frame can take a proper strike.

  2. 2

    Retiring the old keys and closing gaps

    Part of the visit is making the old keys meaningless. Once the new cylinders are in, every previous key is tried to confirm it no longer operates anything, and any remaining door on the old keyway is either upgraded or at least rekeyed so an unknown copy has nowhere to go. The locksmith also closes small gaps found during the assessment: replacing hinge screws with long ones, adjusting a closer, adding a cylinder guard, or moving a thumb-turn away from glass. The door leaves the visit as one coherent assembly rather than one strong part among weak ones.

  3. 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 affects the quote

  1. 1

    Cylinder only or full deadbolt

    Swapping the cylinder inside a sound deadbolt is a smaller job than fitting a new graded deadbolt through the door, and a knob-only door that needs a fresh bore is bigger again.

  2. 2

    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.

  3. 3

    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.

High Security Locks: questions

Advice · (226) 785-2980

What is bumping, and does this stop it?

Bumping uses a specially cut key that is struck while under light turning pressure, bouncing the pins to the shear line for an instant so an ordinary cylinder opens. It works on many standard pin tumblers. A high security cylinder needs its sidebar released by separately positioned finger or rotating pins at the same moment, and a bump key cannot set those, so the plug stays locked. It is one of the clearest advantages of the upgrade.

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.

How long does the installation take?

A cylinder swap with new keys on one door is a short visit. A new deadbolt, reinforced strike and frame repair takes longer, and several doors keyed to a plan take longer again, mostly in bench time pinning cylinders. The locksmith gives you a realistic estimate once the doors have been looked at, because the frame condition and the door preparation matter more than the count of locks alone.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
