High Security Locks

Open 24/7

The pharmacy stockroom, the server closet or the cash office is protected by the same ordinary cylinder as the staff washroom. One lost key on a lanyard would open all of them.

Request a visit

In plain words

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.

Sound familiar?Toronto

The call: 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.

How the visit goes

Hands using a yellow-handled screwdriver at a steel deadbolt plate on a dark door, with a steel knob below.

Scene 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.
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 quoteBloordale Gardens Lock & Key Co.

Condition of the door itself: A solid door that hangs true takes hardware straight away. A dropped, swollen or hollow door may need hinge work, shimming or a recommendation to replace the slab before the lock is worth fitting.
Mortise and older doors: An existing mortise pocket, a thick slab door or an unusual backset can mean a specific cylinder or an adapted preparation, which takes longer than a standard bore.
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.

Questions people ask us

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.

Do I need to replace my whole deadbolt or just the cylinder?

It depends on what you have. If the deadbolt is a good heavy unit that throws a full inch into a proper strike, a high security cylinder can replace the ordinary one and the rest stays. If the deadbolt is light, worn or throws a short bolt, a new graded deadbolt with a hardened bolt is the sensible base and the high security cylinder goes into that. The assessment tells you which, door by door.

What proof do I need to show before locks are changed?

The locksmith confirms that the person ordering the work is entitled to change the locks: the owner, a tenant with the landlord's agreement, or a property or facilities manager for a business. Photo identification and something linking you to the address usually settle it, and for a company a letter or a call to the named contact does the same. It protects you as much as anyone, since the same check stops someone else from changing your locks.
