High Security Locks

Open 24/7

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.

In plain words

Most break-ins do not involve picking; they involve a boot, a pry bar or a key that should never have been copied. High security hardware answers all three. A deadbolt with a full one-inch throw and a hardened core resists sawing and kicking, a reinforced strike with three-inch screws keeps the jamb whole, and a patented keyway means a copy can only be made through the locksmith who holds your system. The pick, bump and drill resistance of the cylinder is the layer on top. The locksmith's job is to fit those layers to your particular door and your particular worries.

The call: The restricted keys you bought years ago are no longer restricted; the locksmith mentioned the patent has run out and blanks are sold openly. Your key control quietly stopped being control.

How the visit goes

Scene 1
Reading the cylinder you have now
The existing cylinder tells the locksmith a great deal. A standard pin tumbler with an open keyway can be picked, bumped and duplicated by anyone with the blank. Worn pins let a key that is not quite right jiggle it open. A cylinder that spins loosely in its housing or shows a scratched face has been attacked or simply worn out. The locksmith identifies the format, whether key-in-knob, rim, mortise or interchangeable core, because that determines which high-security cylinders will drop into your present hardware and which will need a new lock body altogether.
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
Looking after a precision cylinder
High-security cylinders are finer mechanisms than the pin tumblers they replace, and a little care keeps them turning sweetly. Use only the dry lubricant the locksmith recommends, once or twice a year and sparingly, and never household oil, which gathers grit around the finger pins and sidebar. In cold weather, if the key resists, warm it in your hand or use a de-icer rather than forcing it. Insert the key fully before turning. Keep a spare key indoors so a bent or worn key is retired rather than pushed on. Treated this way, the cylinder outlasts the door around it.

What shapes the quoteLawrence Heights Locksmith Services

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.
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.

Straight answers

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 about the glass panel next to my front door?

A sidelight within reach of the inside thumb-turn is the weak point of an otherwise strong door, since a broken pane lets a hand reach the turn. Options include moving the deadbolt further from the glass, a lock function that needs a key inside as well, or a laminated pane. Because everyone must still be able to leave easily, the locksmith talks through the trade-offs and helps you pick the arrangement that suits your household.

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.
