High Security Locks

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.

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?

  1. 1

    Matching the rating to the risk

    Ratings are only useful if someone explains them. A residential deadbolt carries a hardware grade for security, durability and finish based on hammer blows, pulling force and cycle testing. A high-security cylinder carries a separate laboratory listing based on how many minutes it resists picking, drilling and forcing. The locksmith explains what each figure means in practice for your door and points out the rule that matters most: the whole assembly takes the grade of its weakest part. That conversation ends with a recommendation you understand rather than a part number you have to trust.

  2. 2

    Keying several doors sensibly

    When more than one door is upgraded, the locksmith plans the keying before pinning anything. A home usually wants every exterior door on one key. A business often wants staff keys that open the front and their own area, and one manager key that opens everything, arranged as a small master system on the same patented keyway. Cylinders are pinned on the bench, labelled and fitted door by door, and each key is checked against the doors it should open and, just as carefully, the doors it should not. The written key schedule is part of the handover.

  3. 3

    Ordering keys the right way

    Extra keys are now a small procedure rather than an errand. An authorised person contacts the locksmith, the request is checked against the system record, and the key is cut from code so it works as cleanly as the first. New keys are numbered and added to the register. Businesses often issue keys against a signature and collect them when someone leaves, which the register makes simple. Homeowners typically keep two or three spare keys and hold onto the authorisation card. A key cut from a worn copy would not release the sidebar properly, which is one more reason the code route is the only route.

What affects the quote

  1. 1

    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.

  2. 2

    Exit devices and closers on the same door

    Where a commercial door carries a push bar or closer, the new lock must work with them, and adjusting or replacing that hardware is part of the same visit.

  3. 3

    Cylinder rating and format

    A patented residential cylinder, a laboratory-rated commercial cylinder and an interchangeable core sit at different points on the scale, and the format that fits your present hardware decides which lines are available.

High Security Locks: questions

Advice · (226) 777-6122

What information helps before the visit?

A photo of each door's lock from inside and outside, the type of door, whether there is glass nearby and roughly how many keys are in circulation. For a business, a sketch of the doors and who needs to reach each area saves a great deal of time. Mention any door that sticks, has been forced or has a closer or push bar on it. With that, the locksmith arrives with the right formats and a plan to discuss.

Can a high security cylinder be rekeyed later?

Yes. Like any pin tumbler it can be repinned to a new combination by a locksmith who holds the system, so a departed employee's key can be retired without replacing hardware. Some lines use interchangeable cores that swap in moments with a control key, which suits businesses with frequent turnover. Rekeying stays within your registered keyway, so the key control you paid for continues after the change.

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 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.

Period hardware on older homes deserves matching parts, not a mismatched modern set. A locksmith who works among such houses keeps finishes and styles that suit them, so a repaired or replaced lock still looks like it belongs to the door.

49%

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

Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
