However, choosing the correct replacement is critical. Ordering the wrong cam length or barrel size wastes time and increases cost.<\/p>\n\n\n\n<p>This step-by-step guide explains how to remove the existing lock, measure correctly and select the right <a href=\"https:\/\/total-locker-service.com\/LockerLocks.php\">replacement locker locks<\/a> for schools, gyms, workplaces and leisure centres in the UK.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"400\" height=\"363\" src=\"https:\/\/total-locker-service.com\/blog\/wp-content\/uploads\/2026\/02\/camlock31-1.webp\" alt=\"Most UK lockers use cam locks secured by a rear fixing nut\" class=\"wp-image-7777\" srcset=\"https:\/\/total-locker-service.com\/blog\/wp-content\/uploads\/2026\/02\/camlock31-1.webp 400w, https:\/\/total-locker-service.com\/blog\/wp-content\/uploads\/2026\/02\/camlock31-1-300x272.webp 300w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/figure>\n<\/div>\n\n\n<h2 id=\"h-when-should-you-replace-a-locker-lock\" class=\"wp-block-heading\">When Should You Replace a Locker Lock?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The key number is unreadable.<\/li>\n\n\n\n<li>The lock barrel spins freely.<\/li>\n\n\n\n<li>The cam arm is bent or broken.<\/li>\n\n\n\n<li>The master key has been compromised.<\/li>\n\n\n\n<li>The mechanism has been forced.<\/li>\n<\/ul>\n\n\n\n<p>In many cases, replacing the key is sufficient.

If the key is lost and the locker is locked, controlled access may be required. Avoid drilling unless absolutely necessary, as this increases cost.<\/p>\n\n\n\n<h2 id=\"h-step-2-remove-the-retaining-nut\" class=\"wp-block-heading\">Step 2: Remove the Retaining Nut<\/h2>\n\n\n\n<p>Inside the locker door, you will see a threaded barrel secured by a retaining nut.
