: Used by investigators to identify if a lock was tampered with or to gain entry without leaving traces of a "break-in."

: Ideal for antique or rare locks where a blank key is not available.

: The "key" is carefully pulled out. While too soft to turn the lock on its own, it provides a perfect negative mold. This mold is then used to measure pin heights or as a template to cut a permanent metal key. Primary Use Cases

: The liquid compound is injected into the keyway using a fine-tipped applicator. Its low viscosity allows it to reach the deepest crevices of the lock pins.

: Within minutes, the liquid undergoes a chemical reaction to become a semi-rigid, elastic solid.

Essentially, it is a low-viscosity, fast-curing compound—often a silicone or polymer-based material—designed to flow into the intricate chambers of a lock. Unlike traditional mechanical impressioning, which uses metal blanks and physical force, the liquid key method relies on chemical casting to duplicate the internal geometry of the pins or wafers. How the Process Works

: The lock is cleaned and often treated with a release agent to ensure the hardened material doesn't bond to the cylinder.
