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

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.

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.

How the visit goes

Scene 1
Winter, weather and daily use
A door on a farmhouse porch, a condo corridor and a shop on a busy street each see different wear. The locksmith asks how the door behaves in cold weather, whether the key has ever frozen or stuck, how many times a day it is used and whether it slams behind people. High-security cylinders with sidebars and telescopic pins are precise mechanisms and appreciate a door that closes true and a keyway kept clean. The recommendation may include a weather cover for an exposed cylinder, a closer adjustment or a hinge repair so the new hardware lives a long life.
Scene 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.
Scene 3
A key plan that survives staff changes
For a business, the handover includes a key schedule showing every cylinder, every key number and who holds it. When someone leaves, their key comes back and is struck off; if it does not come back, you know exactly which doors it opened and can decide whether one cylinder or several should be repinned. Because the keyway is restricted, a departed employee cannot quietly keep a copy. New hires are issued a numbered key against a signature. The plan lives in a folder or spreadsheet, and the locksmith keeps a matching record so the two can be reconciled whenever you like.

What shapes the quoteBell Ewart Lock Services

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.
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.
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.

Ask us anything about locks

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.
