When a forensic locksmith finds 'warding marks' inside a keyway, this evidence most likely indicates:
Answer: An unauthorized key was attempted or inserted in the lock
Warding marks inside a keyway suggest a key was inserted that did not match the warding profile, indicating an unauthorized key attempt.
The TL-30 rating for a safe indicates it can resist a tool attack for a minimum of:
Answer: 30 minutes using common mechanical and electrical tools
TL-30 (Tool-Resistant, 30 minutes) means the safe resists attack using common tools including electric tools for at least 30 net working minutes.
A forensic locksmith's written report should primarily be structured to allow:

A forensic report must be reproducible by peers, ensuring the methodology is transparent and conclusions can be independently verified.
Key control standards in high-security facilities typically require documenting which information for every key issued?

The term 'false set' in lock manipulation refers to the moment when:
Answer: The plug rotates slightly before all pins are fully set
A false set occurs when the plug rotates a few degrees as the first pin reaches the shear line, giving the manipulator tactile feedback before the lock opens.
When examining a deadbolt for evidence of picking, forensic locksmiths look for 'pick scratches' most commonly located:
Answer: On the bottom of the driver pins and inside the shear line area
Pick scratches appear on the bottom of driver pins and around the shear line because picking tools contact these surfaces during manipulation.
