EMP-Resistant Locks

Sargent and Greenleaf electronic locks are tested and proven EMP-resistant.

Sargent and Greenleaf's high-security electronic locks are proven to withstand military-level EMP attacks, giving you full access to your valuables even after an EMP emergency. S&G tested its most popular gun safe locks, using the U.S. military’s highest EMP impact standard. An independent lab applied a radiant transient electromagnet field on a variety of S&G keypads, following the Military Standard MIL-STD461F, Method RS105 at 50 kV/m peak exposure. At the end of the testing series, the S&G locks were still fully functional. S&G credits the locks’ resilience to the expertise our engineers have from working with high-security locks for U.S. government facilities.

What is EMP

Electromagnetic pulses (EMP) are short bursts of electromagnetic energy that can interfere or damage electrical equipment, thus disabling their functionality. An EMP can occur naturally, such as the pulse from a massive solar flare, or be created by technological devices, typically nuclear weapons. The high-energy particles from such an explosion would cascade down to Earth, interacting with the planet's magnetic field and destroying the electronic systems below, thus crippling the nation's power system.

EMP in the News

"Cyberattacks, intentional electromagnetic interference weapons and high-altitude EMP attacks produced by the detonation of a nuclear device above the atmosphere could cripple our critical infrastructure."

— US News, October 2015

"The grid is utterly unprotected from an EMP attack. It's not adequately protected from cyber or physical sabotage."

— Fox News, October 2015

"The potential for a devastating attack on the U.S. electricity grid remains high on the minds of utility and government leaders, especially in light of the deadly terrorist actions in Paris on November 13."
