A locksmith is asked to assess a commercial door for forced-entry resistance. Which door frame condition most compromises security?
Answer: Wood frame without door reinforcement plates
An unreinforced wood door frame is the most common point of forced entry failure because the strike plate screws pull out under kick-in pressure.
In commercial locksmithing, 'grand master key,' 'master key,' and 'change key' describe a hierarchy. Which key operates the fewest locks?
Answer: Change key
A change key (also called a sub-master or individual key) operates only the specific lock(s) it was cut for — the lowest level of the hierarchy.
Which ANSI door hardware function number designates a classroom lock (locked from outside by key, always free from inside)?
Answer: Function F04
ANSI Function F04 describes the classroom lock function: key locks/unlocks from outside, always free egress from inside.
A commercial safe lock rated UL TL-15 means the safe has been tested to resist attack for:
Answer: 15 minutes using high-powered tools against the door
UL TL-15 means the safe door resisted attack by high-powered tools (drills, grinders, etc.) for a net working time of 15 minutes.
When a commercial locksmith pins a high-security cylinder to a master key system, which additional pin(s) are used compared to a standard system?
Answer: Spools or serrated master wafers (security pins)
High-security cylinders use spool or serrated driver pins that create false sets during picking attempts, increasing pick resistance.
A commercial property manager asks about 'electronic keying.' What best describes this feature?
Answer: Cylinders that can be rekeyed electronically without disassembly
Electronic keying (e.g., Medeco XT, Abloy Protec2) allows cylinder re-programming via a secure electronic key tool without removing the cylinder.
Which lock type provides both mechanical and electronic locking in a single cylinder, often used for commercial retrofits?
Answer: Dual-technology cylinder (e.g., Schlage CO series)
Dual-technology cylinders integrate a credential reader and electromechanical clutch inside the cylinder body, allowing electronic access without replacing the door or frame.
