High Security Locks
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.

A high security cylinder is rated by independent laboratory testing that times how long it holds out against picking, impressioning, drilling, prying and wrenching. The lock body and deadbolt carry a separate hardware grade for strength, cycle life and finish. A locksmith reads those ratings for you and matches them to your door, because a rating on the box means nothing if the door frame is thin or the bolt barely enters the jamb. The visit usually ends with a heavier deadbolt, a reinforced strike fastened into the framing and a cylinder whose keys cannot be copied at a kiosk.
How the visit goesA 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.

How the visit goes

- 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.

Fitting a heavier deadbolt
When the existing deadbolt is light or worn, the locksmith fits a graded deadbolt through the same bore where possible. The bolt throws a full inch and carries a hardened steel pin that turns under a saw blade, and the housing keeps part of the bolt supported against a kick. The latch is set in the edge bore with the correct backset, the exterior housing and interior thumb-turn are joined through the door with the long screws, and the final tightening is done by hand so nothing strips. The bolt is then thrown with the door open and closed to confirm it extends completely.

Proof for insurers, landlords and tenants
You leave with a written record of what was fitted: the cylinder type and its rating, the deadbolt grade, the strike and screws installed, and the key system registration. Insurers sometimes ask for this when a policy specifies stronger hardware, landlords keep it in the property file, and tenants have something to hand back at move-out. It also helps the next locksmith, who can see at a glance what keyway and format the doors carry. Keep the invoice and the key control documents together; they are the paperwork side of a physical upgrade.
In the van
- Box strike
- Pinning kit and plug follower
- Key control authorisation card
- Patented key blanks
- Commercial mortise lock body
What affects the quote
- 1
Hinge and door edge work
Long hinge screws, a hinge-side security stud or repair to a chewed door edge are small items that add up on a door that has been forced before.
- 2
Number of doors
Each door gets its own cylinder or lock, strike work and testing. Several doors on one keyway share the setup cost of the key system but add hardware and time per opening.

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.

High Security Locks: questions
Will the new cylinder fit my existing locks?
Usually. High security cylinders are made in the common formats: key-in-knob and lever, rim, mortise and interchangeable core, and many are designed to drop into popular residential and commercial locks. The locksmith identifies your format and confirms fit before ordering. Where a lock is an odd size or in poor shape, a matching lock body is fitted instead, and the door preparation is reused wherever it is standard.
What is the difference between restricted and patented keys?
A restricted keyway is one the manufacturer supplies to a limited set of dealers, so blanks are harder to obtain but not legally protected. A patented key design is protected by a patent for a fixed term, and making or selling the blank without permission is unlawful during that time. Patented systems give the firmer control; restricted ones give a useful step up. The locksmith explains which your chosen line uses and when any patent expires.
How long does the installation take?
A cylinder swap with new keys on one door is a short visit. A new deadbolt, reinforced strike and frame repair takes longer, and several doors keyed to a plan take longer again, mostly in bench time pinning cylinders. The locksmith gives you a realistic estimate once the doors have been looked at, because the frame condition and the door preparation matter more than the count of locks alone.

What the census means at the door
47%
Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
50%
A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).
Where housing is mixed, the same street can hold a solid wood front door, a steel townhouse door and a metal-clad suite door. A locksmith fits each with hardware suited to its construction, so every neighbour ends up with a door that locks properly.
