The right capacity depends on how many individual keys, bunches and electronic fobs you need to store, how much spare capacity you require and how much physical space those items occupy inside the cabinet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A site with 80 small flat keys may fit comfortably into a 100-position cabinet. Another site with 80 vehicle keys, bulky fobs and multi-key bunches may need a substantially larger or deeper cabinet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Total Locker Service supplies commercial key cabinets ranging from compact units for smaller workplaces through to high-capacity models with up to 600 key positions.

A 100-key cabinet therefore provides positions intended to organise approximately 100 individual keys under suitable conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But hook capacity does not tell you how much physical volume is available around those hooks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The usable capacity can be affected by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the length of each key;<\/li>\n\n\n\n<li>the size of key tags;<\/li>\n\n\n\n<li>vehicle remote controls;<\/li>\n\n\n\n<li>electronic access fobs;<\/li>\n\n\n\n<li>multi-key bunches;<\/li>\n\n\n\n<li>large master keys;<\/li>\n\n\n\n<li>security seals or loops;<\/li>\n\n\n\n<li>hook spacing;<\/li>\n\n\n\n<li>cabinet depth;<\/li>\n\n\n\n<li>and the arrangement of internal hook bars or panels.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is why an organisation storing 100 individual office keys and an organisation storing 100 vehicle key sets should not automatically specify the same cabinet.<\/p>\n\n\n\n<h2 id=\"h-20-key-cabinets-small-commercial-requirements\" class=\"wp-block-heading\">20-Key Cabinets: Small Commercial Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A cabinet in the region of 20 key positions can suit a small commercial site where only a limited number of controlled keys need central storage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>small offices;<\/li>\n\n\n\n<li>shops and retail units;<\/li>\n\n\n\n<li>reception areas;<\/li>\n\n\n\n<li>small workshops;<\/li>\n\n\n\n<li>individual departments;<\/li>\n\n\n\n<li>cleaning cupboards;<\/li>\n\n\n\n<li>small community premises;<\/li>\n\n\n\n<li>and a limited collection of spare keys.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you already have close to 20 keys, however, a nominal 20-key cabinet may be too small from the day it is installed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allow for duplicate keys, newly installed doors, cupboards, lockers or equipment. Moving to the next capacity band may provide a more usable long-term solution.<\/p>\n\n\n\n<h2 id=\"h-50-key-cabinets-small-workplaces-and-departments\" class=\"wp-block-heading\">50-Key Cabinets: Small Workplaces and Departments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A 50-key cabinet is a useful capacity for organisations that have outgrown a small key box but do not yet need a large facilities-management cabinet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may suit:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>small workplaces;<\/li>\n\n\n\n<li>school administrative areas;<\/li>\n\n\n\n<li>maintenance departments;<\/li>\n\n\n\n<li>small care settings;<\/li>\n\n\n\n<li>local offices;<\/li>\n\n\n\n<li>retail premises;<\/li>\n\n\n\n<li>and individual departments within a larger organisation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the current estate contains 35 to 40 keys, a 50-position cabinet may provide some growth capacity. If the organisation is expanding rapidly, however, moving directly to approximately 100 positions may avoid an early replacement.<\/p>\n\n\n\n<h2 id=\"h-100-key-cabinets-medium-commercial-key-estates\" class=\"wp-block-heading\">100-Key Cabinets: Medium Commercial Key Estates<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Around 100 positions is a common commercial capacity because it can accommodate a meaningful key estate without moving into the largest cabinet formats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical users include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>schools;<\/li>\n\n\n\n<li>medium-sized workplaces;<\/li>\n\n\n\n<li>maintenance teams;<\/li>\n\n\n\n<li>warehouses;<\/li>\n\n\n\n<li>property managers;<\/li>\n\n\n\n<li>care facilities;<\/li>\n\n\n\n<li>hotels;<\/li>\n\n\n\n<li>and smaller vehicle fleets.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Before selecting a 100-key model, determine whether the requirement really consists of 100 individual keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If many positions will contain vehicle fobs or several keys on one ring, look at cabinet depth and hook spacing as carefully as the stated capacity.<\/p>\n\n\n\n<h2 id=\"h-200-key-cabinets-facilities-and-estates-teams\" class=\"wp-block-heading\">200-Key Cabinets: Facilities and Estates Teams<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once an organisation is managing approximately 100 or more active keys, the cabinet becomes part of the facilities-management infrastructure rather than simply a secure box on a wall.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A cabinet around 200 positions can suit:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>larger schools;<\/li>\n\n\n\n<li>facilities departments;<\/li>\n\n\n\n<li>industrial sites;<\/li>\n\n\n\n<li>warehouses and distribution centres;<\/li>\n\n\n\n<li>property-management businesses;<\/li>\n\n\n\n<li>larger offices;<\/li>\n\n\n\n<li>healthcare environments;<\/li>\n\n\n\n<li>and modest fleet operations.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">At this scale, organisation becomes increasingly important. Key positions should be numbered and linked to an index or key register so staff can identify missing keys without searching the cabinet manually.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 200-position cabinet should also be assessed for its internal layout. Filling every hook with a bulky tagged bunch may make the cabinet difficult to use even though the nominal hook count is sufficient.<\/p>\n\n\n\n<h2 id=\"h-400-key-cabinets-large-key-estates\" class=\"wp-block-heading\">400-Key Cabinets: Large Key Estates<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A requirement approaching 400 key positions usually indicates a substantial estate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Applications can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>large educational sites;<\/li>\n\n\n\n<li>property and facilities-management organisations;<\/li>\n\n\n\n<li>vehicle fleets;<\/li>\n\n\n\n<li>large industrial premises;<\/li>\n\n\n\n<li>multi-building sites;<\/li>\n\n\n\n<li>hotels and accommodation estates;<\/li>\n\n\n\n<li>large maintenance operations;<\/li>\n\n\n\n<li>and centralised key stores.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">At this level it becomes particularly important to decide whether one large cabinet or several smaller cabinets provides the better operating arrangement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A single large cabinet centralises control. Several cabinets can allow keys to be separated by building, department, risk or function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct choice depends on how the organisation issues and returns keys rather than capacity alone.<\/p>\n\n\n\n<h2 id=\"h-600-key-cabinets-high-capacity-commercial-key-storage\" class=\"wp-block-heading\">600-Key Cabinets: High-Capacity Commercial Key Storage<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Commercial key cabinet ranges can extend to approximately 600 key positions, providing central storage for very large key estates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 600-position cabinet may be relevant for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>large facilities and estates teams;<\/li>\n\n\n\n<li>multi-building organisations;<\/li>\n\n\n\n<li>large property portfolios;<\/li>\n\n\n\n<li>vehicle operations;<\/li>\n\n\n\n<li>industrial estates;<\/li>\n\n\n\n<li>large educational campuses;<\/li>\n\n\n\n<li>and central key-control rooms.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">High-capacity cabinets should not be selected purely because they provide the greatest number of hooks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consider how staff will locate, issue and return several hundred keys. Clear numbering, indexing and separation by function become increasingly important as capacity rises.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For commercial options extending to high-capacity models, browse our range of <a href=\"https:\/\/total-locker-service.com\/Key-Cabinets.php\"><strong>secure key cabinets<\/strong><\/a>.<\/p>\n\n\n\n<h2 id=\"h-how-much-spare-key-cabinet-capacity-should-you-allow\" class=\"wp-block-heading\">How Much Spare Key Cabinet Capacity Should You Allow?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A key cabinet that is completely full on installation has no practical growth capacity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a general planning starting point, allowing approximately <strong>20\u201330% spare capacity<\/strong> can provide room for future additions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Current requirement<\/th><th>20% allowance<\/th><th>30% allowance<\/th><th>Capacity to consider<\/th><\/tr><\/thead><tbody><tr><td>20 keys<\/td><td>24<\/td><td>26<\/td><td>Approximately 30+<\/td><\/tr><tr><td>40 keys<\/td><td>48<\/td><td>52<\/td><td>Approximately 50\u201360+<\/td><\/tr><tr><td>75 keys<\/td><td>90<\/td><td>98<\/td><td>Approximately 100<\/td><\/tr><tr><td>150 keys<\/td><td>180<\/td><td>195<\/td><td>Approximately 200<\/td><\/tr><tr><td>300 keys<\/td><td>360<\/td><td>390<\/td><td>Approximately 400<\/td><\/tr><tr><td>450 keys<\/td><td>540<\/td><td>585<\/td><td>Approximately 600<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This is not a rigid rule.

That undermines the reason for installing an organised key cabinet.<\/p>\n\n\n\n<h2 id=\"h-individual-keys-versus-key-bunches\" class=\"wp-block-heading\">Individual Keys Versus Key Bunches<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common errors when selecting a key cabinet is counting bunches as though they occupy the same space as individual keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A small flat key hanging vertically occupies relatively little room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bunch containing:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>five or six keys;<\/li>\n\n\n\n<li>a large identification tag;<\/li>\n\n\n\n<li>a security fob;<\/li>\n\n\n\n<li>and a substantial key ring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">can occupy several times as much internal volume.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If bunches make up a significant proportion of the requirement, consider a <strong>deep key cabinet<\/strong> or a cabinet whose internal hook arrangement can accommodate greater spacing.<\/p>\n\n\n\n<h2 id=\"h-vehicle-keys-and-electronic-fobs-need-more-space\" class=\"wp-block-heading\">Vehicle Keys and Electronic Fobs Need More Space<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vehicle keys are another situation where hook count alone can be misleading.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Modern vehicle keys can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>remote-control bodies;<\/li>\n\n\n\n<li>electronic transponders;<\/li>\n\n\n\n<li>large plastic housings;<\/li>\n\n\n\n<li>fleet identification tags;<\/li>\n\n\n\n<li>fuel cards;<\/li>\n\n\n\n<li>and several associated keys on one ring.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These may protrude considerably further from the back of the cabinet than ordinary door keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For fleet, garage, dealership or vehicle-management applications, check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>internal cabinet depth;<\/li>\n\n\n\n<li>clearance between hook rows;<\/li>\n\n\n\n<li>clearance between keys and the door;<\/li>\n\n\n\n<li>and whether bunches overlap when the cabinet is fully populated.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A deeper 100-position cabinet may be more suitable than a shallow cabinet with a nominally greater hook capacity.<\/p>\n\n\n\n<h2 id=\"h-why-cabinet-depth-matters\" class=\"wp-block-heading\">Why Cabinet Depth Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Width and height determine how many hook positions can be distributed across the cabinet.

class=\"wp-block-paragraph\">A useful capacity exercise separates these categories before adding them together.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This may show that one very large cabinet is

Cabinet Capacity for Vehicle Fleets<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vehicle operations should be especially cautious about selecting cabinets from the advertised hook count alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A fleet of 80 vehicles may involve more than 80 physical key items when spare keys, duplicate sets and associated access keys are included.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vehicle remotes can also be much bulkier than conventional door keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before ordering, assemble several representative key sets and measure their approximate depth and width when hanging naturally.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This provides a much better indication of the internal

class=\"wp-block-paragraph\">The right key cabinet should have enough room for the keys you manage today without becoming full as soon as new keys are added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a small office, that may mean approximately 20 or 50 positions. Larger workplaces, schools and facilities teams may need around 100 or 200 positions. Large estates and fleet operations may require 400 or 600-position cabinets or several cabinets divided by function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always consider the physical size of the contents as well as the stated hook count. Vehicle fobs, large tags and multi-key bunches can require deeper cabinets and greater spacing than individual flat keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Browse Total Locker Service&#8217;s range of <a href=\"https:\/\/total-locker-service.com\/Key-Cabinets.php\"><strong>secure key cabinets<\/strong><\/a>, including compact, deep, high-capacity, high-security and electronic options for commercial key management.<\/p>\n\n\n\n<h2 id=\"h-commercial-key-cabinet-size-faqs\" class=\"wp-block-heading\">Commercial Key Cabinet Size FAQs<\/h2>\n\n\n\n<div itemscope itemtype=\"https:\/\/schema.org\/FAQPage\">\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">What size key cabinet do I need for 20 keys?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">If you currently manage 20 keys, choose a cabinet with additional capacity rather than exactly 20 positions. Approximately 25 to 30 or more positions can provide space for spare and future keys, depending on the expected growth of the site.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">What size key cabinet do I need for 50 keys?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">For 50 current keys, consider a cabinet larger than 50 positions if further keys are likely to be added. Around 60 to 100 positions may provide a more practical growth allowance, depending on the key type and site.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">What size key cabinet do I need for 100 keys?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">A site already storing 100 keys should normally consider more than 100 positions if future expansion or spare keys are expected. Also check cabinet depth if the collection contains bulky fobs, tags or key bunches.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Are 200, 400 and 600-key cabinets available?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Yes. Commercial key cabinet ranges include high-capacity options for facilities teams, estates, fleets and other organisations managing hundreds of keys. Total Locker Service offers commercial key-storage ranges extending to 600 key positions.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">How much spare capacity should I allow in a key cabinet?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Approximately 20 to 30 percent spare capacity is a useful starting point for many organisations, although rapidly expanding sites may need more. The appropriate allowance depends on expected changes to buildings, vehicles, lockers, equipment and spare-key requirements.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Does a 100-key cabinet always hold 100 key bunches?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Not necessarily. Nominal capacity normally refers to key positions or hooks. Large bunches, tags and fobs can occupy substantially more space than individual keys, so cabinet depth and hook spacing should also be considered.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Do vehicle keys need a deeper key cabinet?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Often they do. Vehicle remotes, electronic fobs and large key rings can project much further from the cabinet back than ordinary flat keys. A deeper cabinet can provide better clearance and reduce overcrowding.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Should I choose one large cabinet or several smaller key cabinets?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Either arrangement can work. One large cabinet centralises storage, while several smaller cabinets can separate keys by building, department, risk or function. Choose the arrangement that best matches how authorised staff issue and return keys.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Why are some large key cabinets double door?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">High-capacity cabinets can become wide. A double-door design can reduce the swing required by each door and provide practical access to large internal key-storage areas. Always check external dimensions and opening clearance before installation.<\/p>\n<\/div>\n<\/div>\n\n<div itemprop=\"mainEntity\" itemscope itemtype=\"https:\/\/schema.org\/Question\">\n<h3 itemprop=\"name\">Where can I buy secure commercial key cabinets in the UK?<\/h3>\n<div itemprop=\"acceptedAnswer\" itemscope itemtype=\"https:\/\/schema.org\/Answer\">\n<p itemprop=\"text\">Total Locker Service supplies secure key cabinets for commercial use, including compact, high-capacity, deep, high-security and electronic key-storage options with ranges extending to hundreds of key positions.<\/p>\n<\/div>\n<\/div>\n\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Choosing a commercial key cabinet is not simply a matter of counting the keys you have today.
