And a shared code generally does not allow identifying each user.<\/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 code that releases the mechanism<\/h2>\n\n\n<p class=\"wp-block-paragraph\">On a door, entering the correct combination usually allows operating a handle or button. Models with keys and safe dials do not work the same way.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The number of digits, possible combinations, and the code change procedure depend on the product. Therefore, the user manual should be consulted rather than applying a universal method.<\/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\">Daily convenience benefits<\/h2>\n\n\n<p class=\"wp-block-paragraph\">No batteries means no need for battery replacement, and a code eliminates the need to distribute certain keys. For a small group of users, a mechanical lock can offer a simple solution.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Operation does not depend on an app or a network. However, it's always essential to choose a product suited to the frequency of access and the environment: not all models are suitable for outdoor use.<\/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\">Know the limits<\/h2>\n\n\n<p class=\"wp-block-paragraph\">A code can be shared, observed, or forgotten. When a person no longer needs access to a location, changing the combination may require notifying the entire group. Individual rights, schedules, and logs are generally not available on a purely mechanical system.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The resistance to forced entry depends on the complete lock, the door, and the installation. The presence of a keypad alone does not constitute a certified security level.<\/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\">Select and have the right model installed<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Check the door opening direction, door thickness, mounting dimensions, internal release mechanism, and any emergency opening. For a safe, the lock must be compatible with the equipment and its certification.<\/p>\n\n\n<p class=\"wp-block-paragraph\">After installation, test the door release in open position, then under real-world conditions. Retain the instruction manual and plan for a code change procedure. If you require managing multiple user profiles, an electronic access control may be more suitable.<\/p>\n\n<\/section>\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 Locking &amp; protection<\/p>\n\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/www.multisecu.fr\/en\/glossaire\/verrou-de-securite\/\">The security deadlock <span aria-hidden=\"true\">\u2197<\/span><\/a><\/h3>\n\n\n<p class=\"wp-block-paragraph\">A security lock adds a barrier to a door or equips an appropriate access point.
