A factory installed lock is sufficient to prevent a forced entry. True or false?

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (B)

Entry security relies on more than the presence of a factory-installed lock. A standard, factory-installed lock is meant for everyday use, not to withstand a determined forced entry. An intruder can defeat or bypass it with common tools, and if the door frame, strike plate, or hinges aren’t properly reinforced, the door can be forced open regardless of the lock. So the lock alone cannot be relied upon to prevent a forced entry. A layered approach—strong deadbolts, reinforced strike plates with long screws into studs, and secure door/frame hardware—provides much better protection.
