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.

Request a visit

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.

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
Heavy hardware for commercial doors
Storefront, warehouse and office doors take heavy-duty lock bodies rather than residential deadbolts. Depending on the door, that means a commercial deadbolt or mortise lock with a hardened cylinder guard, a free-spinning collar that defeats wrenches, and a laboratory-rated cylinder inside it. Narrow aluminium doors get a deadlock made for their stile. The locksmith fits the lock to the existing preparation where it is standard, adjusts the strike in the frame, and confirms that any exit device or closer on the same door still works exactly as before so people leave easily while the door holds from outside.
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.

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.
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.

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.
