It might be small enough to fit in your pocket, but we know that the key to your home is the key to your whole world. Our family business was born of that idea of protection - it’s what inspired our founder, William F. Banham, to create the world’s first automatic door bolt a century ago, ensuring the security of the family dress shop. And it’s what inspired us to launch our industry-leading Key Registration service. 

Blueprint design of a mechanical fist Banham invented the first automatic door bolt in 1926 lock with labeled parts, keyhole, and figure 1, on a black background with technical specifications.

Protecting what you cherish the most starts with our patented dimpled Mark III keys, which are only ever cut by our thoroughly vetted, expert key cutters. We never outsource the process, and our registration service - which comes as standard with all of our keys - this means that only our trusted Banham team can be authorised to duplicate or replace our keys, and that we’ll only ever do so with your permission. Put simply, you’re in control, and can trust that your key is in the safest of hands and we will never replicate it without your say-so. Our fully audited system will keep a record of any activity on your account so you’ll never lose track. It’s yet another layer of protection that you can expect from Banham.


When you choose any of our award-winning locks or cylinders which come paired to your unique, patent protected Mark III keys, you’ll receive our Key Registration form. All we need are a few pertinent details about your set-up, including the location of your locks; then post it to us at Banham HQ in Earlsfield for secure processing. A lost form isn’t a problem; our team is on hand to guide you. Key registration is available to homeowners, companies, and managing agents, depending on whether it’s your home or business that you’ve entrusted to us. 

Once you’re registered, not only are you protected against unauthorised copies, but you’ll also benefit from a simplified process should you need a replacement or duplicate key at any time: just visit any Banham showroom with your key and photo ID, or authorise someone else to collect one of your behalf by filling out a quick form online. You can also grant permission to a named individual - either within your business, or a Managing Agent - with a request on letterhead paper.
