The objective is to increase the overall resistance.<\/p>\n\n<\/div>\n\n\n<section id=\"section-1\" class=\"wp-block-group msg-chapter is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">A manual opening<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Unlike a destructive attack, picking targets the key recognition mechanism. It may leave no obvious traces, but the absence of traces does not alone prove that a lock has been picked.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The techniques and tools depend on the system. Keys produced by impression and those using percussion belong to different methods: grouping them under a single term can lead to confusion.<\/p>\n\n<\/section>\n\n\n<section id=\"section-2\" class=\"wp-block-group msg-chapter is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Select a cylinder with better protection<\/h2>\n\n\n<p class=\"wp-block-paragraph\">The internal design may include features intended to complicate manipulation. It's essential to examine the model's characteristics rather than relying solely on the number of pins or an isolated 'anti-pick' mention.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The key reproduction conditions and the possibility of managing access with a single key can also influence the choice. These address different needs from mechanical resistance.<\/p>\n\n<\/section>\n\n\n<section id=\"section-3\" class=\"wp-block-group msg-chapter is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Consider the full door assembly<\/h2>\n\n\n<p class=\"wp-block-paragraph\">An appropriate door furniture or cylinder guard contributes notably to limiting certain physical attacks. It does not automatically make all manipulations impossible.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The lock, its strike plates, the frame and the hinges must be examined alongside the cylinder. An A2P certification applies to a defined configuration: changing a component without adhering to accepted references may invalidate this configuration.<\/p>\n\n<\/section>\n\n\n<section id=\"section-4\" class=\"wp-block-group msg-chapter is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Following a suspected intrusion<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Check the lock cylinder and the closure before continuing use if unusual operation is observed. The key catch or the movement of the door furniture alone does not allow for identifying the cause.<\/p>\n\n\n<p class=\"wp-block-paragraph\">MULTISECU can inspect the installation, differentiate wear and degradation, and propose an appropriate repair or reinforcement. The aim is to restore reliable access, with clear explanations regarding the limits and capabilities of the equipment.<\/p>\n\n<\/section>\n\n\n<div class=\"wp-block-group msg-detail-media is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"msg-kicker wp-block-paragraph\">IN IMAGES<\/p>\n\n\n<div class=\"wp-block-group msg-gallery is-layout-flow wp-block-group-is-layout-flow\">\n<figure class=\"wp-block-image size-full msg-photo msg-detail-photo\"><img decoding=\"async\" width=\"550\" height=\"550\" src=\"https:\/\/www.multisecu.fr\/wp-content\/uploads\/2023\/11\/y9-100833-et-cle.jpg\" alt=\"y9 100833 and cle example of A2P resistant lock against picking\" class=\"wp-image-1623\" srcset=\"https:\/\/www.multisecu.fr\/wp-content\/uploads\/2023\/11\/y9-100833-et-cle.jpg 550w, https:\/\/www.multisecu.fr\/wp-content\/uploads\/2023\/11\/y9-100833-et-cle-300x300.jpg 300w, https:\/\/www.multisecu.fr\/wp-content\/uploads\/2023\/11\/y9-100833-et-cle-150x150.jpg 150w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/figure>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/section>\n\n\n<section class=\"wp-block-group msg-section msg-related is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group msg-wrap is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"msg-kicker wp-block-paragraph\">FIND OUT MORE<\/p>\n\n\n<h2 class=\"wp-block-heading\">Related terms.<\/h2>\n\n\n<div class=\"wp-block-group msg-term-grid is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group msg-term is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"msg-kicker wp-block-paragraph\">GLOSSARY \u00b7 Components &amp; identification<\/p>\n\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/www.multisecu.fr\/en\/glossaire\/les-goupilles\/\">The wafers in the cylinder <span aria-hidden=\"true\">\u2197<\/span><\/a><\/h3>\n\n\n<p class=\"wp-block-paragraph\">The wafers are small movable components found in many cylinders.
