High Security Locks

Open 24/7

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.

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: Your shop has had four employees leave in two years and each one had a key. Rekeying every time is getting old, and the hardware store will cut a copy for anyone who walks in with the original.

How the visit goes

Steel door lever on an oval plate with a key in the lock, beside a row of metal bolts on the edge.

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
Reinforcing the strike and frame
The strike is where a forced door actually fails, so it gets serious attention. The stamped plate comes off and the pocket is deepened to accept a box strike or a long reinforced strike, fastened with three-inch screws that pass through the jamb into the wall framing. Stripped or split wood is filled and doweled first so the screws have something to hold. Where the frame is thin, a wrap-around reinforcer around the door edge and a full-length jamb plate are options. The result is a bolt that ties the door into the house rather than into a strip of trim.
Scene 3
A known number of keys
The most noticeable change is not in the door but in your head. You know exactly how many keys exist, who holds each one and that nobody can add to that number without your authorisation. The system is registered in your name with the locksmith, so a request for an extra key comes back to you rather than being filled at a counter somewhere. Keep the authorisation card or login details somewhere safe and separate from the keys. When a key is lost, tell the locksmith; the record is updated and you can decide together whether that key's loss warrants any further step.

What shapes the quoteBradburn Subdivision Lock & Key Co.

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.
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.
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.

You asked, we answered

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 actually makes a lock high security?

Three things working together. The cylinder has a second locking mechanism, usually a sidebar released by finger pins or rotating pins, plus hardened steel in the path of a drill, so picking, bumping and drilling take far longer than on an ordinary lock. The deadbolt and strike are heavier and fastened into the framing. And the key is cut on a patented or restricted blank that only an authorised person can have copied. Remove any one and the door is weaker than the label suggests.

What about the glass panel next to my front door?

A sidelight within reach of the inside thumb-turn is the weak point of an otherwise strong door, since a broken pane lets a hand reach the turn. Options include moving the deadbolt further from the glass, a lock function that needs a key inside as well, or a laminated pane. Because everyone must still be able to leave easily, the locksmith talks through the trade-offs and helps you pick the arrangement that suits your household.
