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.

Request a visit

In plain words

The service begins with a conversation about what the door protects and what worries you, then a close look at the door as a whole: the cylinder, the bolt, the strike, the frame, the hinges and any glass nearby. From that the locksmith recommends a level of protection that matches the risk, fits it, and sets up the key system in your name. From then on, extra keys are cut only when you authorise them, and you receive a record of which key opens which door. It is the mechanical answer to the question most people eventually ask: who else has a key to this?

How the visit goes

Scene 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.
Scene 2
Upgrading the cylinder in place
Where the existing lock body is sound, the locksmith removes the ordinary cylinder and fits a high-security one of the same format, so your deadbolt or lever stays and only the working heart changes. The new cylinder brings a sidebar released by finger or rotating pins, hardened steel inserts in the path of a drill, and a keyway that accepts only the controlled blank. Keys are cut from code on a machine that handles the side bitting. The tailpiece or cam is matched so the bolt throws fully, then the cylinder is fixed with its set screw and tested with every key.
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 quoteLeaside Lock Experts

Documentation and registration: Setting up the key register, recording signatories and providing a written schedule of cylinders and keys is real work on a business system and is listed rather than hidden.
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.
Condition of the door itself: A solid door that hangs true takes hardware straight away. A dropped, swollen or hollow door may need hinge work, shimming or a recommendation to replace the slab before the lock is worth fitting.

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.

Should I upgrade the front door only, or every door?

Start with the doors that matter and the ones that are weakest, which are often not the same. Front doors usually carry the sturdiest hardware already; the side door by the driveway, the door from the garage and the basement walkout often carry the lightest locks and get the least attention. The assessment walks the whole perimeter with you so the upgrade goes where entry is most likely, and the remaining doors can join the same key later.

What proof do I need to show before locks are changed?

The locksmith confirms that the person ordering the work is entitled to change the locks: the owner, a tenant with the landlord's agreement, or a property or facilities manager for a business. Photo identification and something linking you to the address usually settle it, and for a company a letter or a call to the named contact does the same. It protects you as much as anyone, since the same check stops someone else from changing your locks.
