What primary mechanism does a prying tool utilize for unlocking?

Prying tools are designed to exploit leverage and mechanical advantage, enabling users to apply enough pressure to disengage or manipulate locking mechanisms. The primary mechanism involves inserting the tool into a gap and applying pressure, allowing the tool to pry open a lock or door without causing significant damage. This technique relies on the physical force exerted through leverage to overcome the resistance of the locking system.

The other options refer to methods that are not characteristic of how prying tools operate. For instance, magnetic interference pertains more to electronic lock systems rather than physical prying tools. Similarly, the use of electric signals is specific to electronic unlocking mechanisms, which do not involve physical prying. Manual twisting of lock bolts might be applicable to certain lock designs but does not represent the primary action of a prying tool, which focuses on leverage rather than twisting movements.
