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.

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?

Sound familiar?Bedford Park

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
Who holds keys and who should
For a business or a rental, the locksmith asks to see the key list, or helps you start one. Which keys exist, who carries them, which doors they open, and what happens when someone leaves. This is where the case for a patented or restricted key system becomes clear, because the system replaces guesswork with a register: every key numbered, every order authorised by a named person, and no blanks available outside the locksmith who manages it. The locksmith also asks how many people need to reach each area so the keying plan reflects the way the building actually runs.
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 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 quoteDavisville Lock & Key Co.

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.
Strike and frame reinforcement: A reinforced strike with long screws is modest work on a healthy frame. Deepening the pocket, filling split wood, fitting a jamb plate or a wrap-around reinforcer adds materials and time.
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.

How do I order extra keys later?

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do.

Are high security locks only for businesses?

Not at all. Homes are the most common place they are fitted, especially after a move, a break-in nearby, or the realisation that too many keys have been handed out over the years. A graded deadbolt with a patented cylinder and a reinforced strike is a modest, quiet upgrade for a front or side door. Businesses tend to go further, with laboratory-rated cylinders, heavy lock bodies and a documented key system across many doors.

Can all my doors be on one key?

Yes, and most homes ask for exactly that. Every exterior cylinder is pinned to the same combination so one controlled key opens the front, back, side and garage entry. A gate or shed padlock on the same keyway can join it. For businesses, the same keyway can carry a small master system where staff keys open only their areas and a manager key opens everything. The keying plan is agreed before any pinning is done.
