Retrofitting one onto an existing door lock improves both security and day-to-day convenience, since access can be granted or changed centrally rather than through physical keys. This makes keypads particularly useful for high-footfall premises such as hotels, office buildings and public sector facilities, where managing who holds a key quickly becomes impractical.<\/strong><\/p>\n<p><strong><\/strong><\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/blog.simons-voss.com\/wp-content\/uploads\/2024\/05\/system3060-identifitkationsmedien-moodvisual-PinCode-760&#215;434-1.jpg&#8221; alt=&#8221;M\u00f6belschl\u00f6sser von SimonsVoss&#8221; title_text=&#8221;Zahlencode Tastatur&#8221; align=&#8221;center&#8221; force_fullwidth=&#8221;on&#8221; admin_label=&#8221;Bild&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; border_color_all=&#8221;#d0040d&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][et_pb_text ul_type=&#8221;square&#8221; ul_item_indent=&#8221;50px&#8221; ul_item_indent_tablet=&#8221;65px&#8221; ul_item_indent_phone=&#8221;0px&#8221; ul_item_indent_last_edited=&#8221;on|phone&#8221; admin_label=&#8221;Text&#8221; _builder_version=&#8221;4.16&#8243; ul_text_color=&#8221;gcid-2fdf5b9f-737f-44b9-96d6-24a10ab09aac&#8221; ul_line_height=&#8221;1.4em&#8221; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; global_colors_info=&#8221;{%22gcid-2fdf5b9f-737f-44b9-96d6-24a10ab09aac%22:%91%22ul_text_color%22%93}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<h2><span style=\"font-weight: 400;\"><\/span><\/h2>\n<h2><span style=\"font-weight: 400;\"><\/span><\/h2>\n<h2><span style=\"font-weight: 400;\">\u25ba Who Uses PIN Code Keypads and Where<\/span><\/h2>\n<h3><span style=\"color: #f18c72;\"><strong><\/strong><\/span><\/h3>\n<h3><span style=\"color: #f18c72;\"><strong><\/strong><\/span><\/h3>\n<p><span><a href=\"https:\/\/www.simons-voss.com\/en\/Access-control\/pincode-keypad-ax.html\">PIN code door locks<\/a><\/span> suit a wide range of commercial settings, and the main users include facility managers responsible for large multi-tenanted properties, who find keypads particularly useful when external contractors are involved or when numerous separate units need managing, as is often the case in larger residential complexes.

Industrial sites rely on electronic keypad locks to meet robust security requirements, and private and public sector offices use them to enhance security while monitoring visitor traffic.

A wireless keypad lock communicates with other building security systems, allowing access to be managed centrally. A standalone keypad lock is ideal for individual doors that don&#8217;t need to connect to a central system, since it operates entirely independently once installed on the door. A smart lock is the most advanced option, offering control through a smartphone app and often adding features such as access logging and remote access.<\/p>\n<p><strong>In short: standalone locks suit a single door, wireless locks suit a centrally managed building, and smart locks add app control and logging on top.<\/strong><\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/blog.simons-voss.com\/wp-content\/uploads\/2024\/07\/pincode-SV.jpg&#8221; alt=&#8221;Pincode Tastatur von SimonsVoss&#8221; title_text=&#8221;Pincode Tastatur von SimonsVoss&#8221; align=&#8221;center&#8221; force_fullwidth=&#8221;on&#8221; admin_label=&#8221;Bild&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; border_color_all=&#8221;#d0040d&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][et_pb_text ul_type=&#8221;square&#8221; ul_item_indent=&#8221;50px&#8221; ul_item_indent_tablet=&#8221;65px&#8221; ul_item_indent_phone=&#8221;0px&#8221; ul_item_indent_last_edited=&#8221;on|phone&#8221; admin_label=&#8221;Text&#8221; _builder_version=&#8221;4.16&#8243; ul_text_color=&#8221;gcid-2fdf5b9f-737f-44b9-96d6-24a10ab09aac&#8221; ul_line_height=&#8221;1.4em&#8221; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; global_colors_info=&#8221;{%22gcid-2fdf5b9f-737f-44b9-96d6-24a10ab09aac%22:%91%22ul_text_color%22%93}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<h2><span style=\"font-weight: 400;\">\u25ba <\/span>Functions and Features<\/h2>\n<p><span style=\"font-weight: 400;\"><\/span><\/p>\n<p>Retrofitting a door lock with a PIN code keypad does more than improve security and ease of use, since it also extends the range of available functions.
