❓ Frequently Asked Questions
What is a deadbolt and how does it differ from a spring latch lock?
A deadbolt moves a solid bolt into the door frame and is held in place by a key or turning knob. It does not rely on springs to retract, making it more resistant to forced entry than a spring latch lock, which uses a spring-loaded bolt that retracts when the handle is turned.
What is a mortise lock and why is it often more secure than a standard cylindrical lock?
A mortise lock is installed inside a pocket cut into the door edge and typically uses a larger, more robust mechanism and strike plate. Its design offers greater strength and durability, giving higher security than many standard cylindrical locks.
What is a padlock and what are common types of padlocks?
A padlock is a portable lock with a detachable shackle. Common types include keyed padlocks and combination padlocks, with varying body materials and shackle sizes for different security needs.
What is a master key system and what is a key-alike system?
In a master key system, locks have individual keys plus a master key that opens all the selected locks. A key-alike system uses the same key for multiple locks, offering convenience but reducing the number of keys needed for access.
