ServiceLock Replacement & Upgrade
Our high security visits start at the kitchen table with a question about what you are protecting and who you are worried about. From that we choose a level: a solid graded deadbolt for one household, a full restricted system for another.
Layer 1The key
You run a home office with client files and equipment, and your insurer has asked what kind of lock is on the door. The honest answer is the builder's knob lock and a light deadbolt from when the house was new.
Layer 2The cylinder
Three teenagers, a dog walker, a cleaner and one house key that keeps going missing. You are tired of cutting copies and would rather give each person a code you can switch off, with a proper deadbolt behind it.
Layer 3The bolt and strike
The front door has a handsome lever and a keyed knob, and that is all. Nothing above it.
Layer 4The door and frame
The shop's aluminum door has a bent meeting stile and the hookbolt is jammed half out. The alarm did its job and the display is untouched, but the entrance will not close properly and opening time is hours away.
High Security Locks. You run a home office with client files and equipment, and your insurer has asked what kind of lock is on the door.
Request a visitIt usually points to the mortise case rather than the cylinder, and it is a common complaint on commercial doors. Inside the case a return spring, a worn hub, or another part of the latch's drive path can have failed, so the lever moves without driving the latch. The locksmith gets the door open, draws the case out of the door edge, replaces the worn part, cleans and greases the contact points and refits everything, then tests lever, key and thumb-turn together.
No. On a conventional pin-tumbler cylinder, the housing, springs and top pins are untouched and only the bottom pins are exchanged for the same grade of part the lock left the factory with; a homeowner-rekeyable design is reset through its own procedure instead, and a high-security cylinder may also need its sidebar or finger-pin elements reset. If the locksmith notices worn parts, replacing them is offered as a separate step, leaving the lock stronger, not weaker.
The new bolt will only lock as smoothly as the door and frame let it, so the locksmith deals with the cause as part of the installation. A door that has sagged on loose hinges gets longer hinge screws or a shim, thick weatherstrip is trimmed, and the strike is set from the bolt's actual position with the door closed. The pocket is bored deep enough for a full throw. Afterwards the bolt should slide with fingertip effort.
Rekey when the hardware is sound and the problem is the key: a lost copy, a move, or too many keys for one house. Replace when the mechanism itself is worn, the housing or bolt is damaged, the grade was never suitable for the entrance, or you want a different function, finish or a keypad. Many visits do both, keeping good locks and rekeying them while replacing the tired ones, all to one key.
