High Security Locks

Open 24/7

A colleague showed you a video of a lock being opened with a bump key in a few seconds. Then you went home and noticed your own deadbolt is the same style, bought at a hardware store a decade ago.

In plain words

This service suits anyone who wants to stop wondering. Homeowners who have inherited unknown keys with a house, landlords who want one controlled key system across units, and businesses protecting stock, records or medication all ask for it. The locksmith explains the choices in plain terms, from a graded deadbolt with a patented cylinder up to laboratory-rated cylinders and heavy commercial lock bodies, and helps you decide which doors deserve which level. Then the work is done cleanly, every key is tested in every lock, and you leave with the documents that let you control future keys.

The call: 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.

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
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.
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 quoteCobourg Lock & Key Co.

Master keying: Arranging staff keys, area keys and a manager key on one system takes bench time to plan and pin, and the more levels you want, the more careful that planning is.
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.
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.

Short answers to common questions

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 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.

Why does the locksmith care so much about the strike plate?

Because that is where a kicked door fails. The bolt is strong, but it sits in a pocket in the jamb held by a thin plate and short screws, and a boot splits the wood around it. A reinforced strike or box strike fastened with three-inch screws into the wall framing spreads the blow along the frame. It is the least visible part of the upgrade and often the one that does the most.
