High Security Locks
A pick-resistant cylinder in a hollow door with a two-screw strike is a locked padlock on a paper bag. We start with the door and frame, because putting the effort there first is what makes the cylinder upgrade worthwhile.
Which one do I need?
- The bookkeeper who set the office safe's code retired in a hurry, and the float cash for tomorrow's registers is sitting behind a keypad nobody else in the building can operate.Safe Opening & Combination Change
- A dinner service ends with a stack of bills and a handful of credit slips, and right now they sit in an unlocked cash box on a shelf until morning, because nobody has gotten around to anything sturdier.Safe Installation & Servicing
- After the attempted break-in the police officer pointed at your door and said the strike plate was held by two short screws.High Security Locks
High Security Locks
Cylinders and deadbolts built to resist picking, bumping and drilling, keys that cannot be copied without authorisation, and safes opened or installed.
Safe Opening & Combination Change
Mechanical dial or electronic keypad?
The two lock families are opened in entirely different ways, so telling them apart comes early. A mechanical dial relies on a wheel pack turned into alignment by hand, reading resistance and feel rather than any battery or circuit. An electronic keypad instead depends on a stored code and a power source; some models add a reset or override sequence, though many need that connection made at the lock body inside the container rather than from outside.
Some commercial safes carry both, a keypad for daily use with a mechanical dial as a backup, and each half is assessed on its own terms. Confusing the two wastes time trying an approach the lock was never built to respond to.
