ALOA Lock Picking and Bypass Techniques 3

Question 1

A wafer lock is commonly found in which application?

Accepted Answer

Filing cabinets and automobile doors

Answer

Wafer locks are low-security locks commonly found in filing cabinets, desk drawers, and older automobile doors.

Question 2

What is the key difference between a spring latch and a deadlatch regarding bypass vulnerability?

Accepted Answer

A deadlatch has an auxiliary plunger that locks the bolt when the door is closed, preventing loiding

Answer

A deadlatch plunger depresses when the door closes, locking the latch bolt solid and making it immune to loiding or credit-card bypass.

Question 3

Which ALOA-recognized ethical principle requires locksmiths to confirm customer identity and legal right before bypassing a lock?

Accepted Answer

Authorization verification

Answer

Authorization verification is an ethical and legal requirement for locksmiths to confirm the requester has legal authority over the property before performing bypass services.

Question 4

What does 'false set' mean during single-pin picking of a lock with security pins?

Accepted Answer

The plug partially rotates but stops because a spool pin is partially across the shear line

Answer

A false set occurs when a spool pin's narrow waist crosses the shear line, letting the plug rotate slightly but not fully open.

Question 5

Which bypass technique involves inserting a thin tool above or below the latch bolt to manipulate the linkage inside the lock body?

Accepted Answer

Loiding/shimming the latch linkage

Answer

Some latches can be bypassed by inserting a thin shim or wire to directly actuate the latch retraction linkage inside the lock body.
