Your Questions Answered

What makes Banham locks different?

Banham locks have been a security gold standard since 1926, when our founder invented the world’s first automatic door bolt. 

Hand crafted in Britain using time‑honoured forging processes including molten metal casting, hot stamping and skilled lock assembly, our locks are renowned for patented precision‑engineering and exceptional strength.

Are Banham locks British Standard approved?

Yes. Our front door locks are compliant with BS3621, the insurance‑approved security standard for external door locks.

Learn More

Can Banham locks be keyed alike?

Yes. Our locks can be keyed alike, meaning that one of our patented dimpled keys can operate multiple door locks on your property for ease and convenience.

How secure are Banham locks?

All of our locks are known for their superior strength and precision engineering and the lock comes with various security features, one of which is our Key Registration system which means we will only copy a Mark III key with your authorisation.

Can Banham locks be installed on existing doors?

Yes. We always recommend changing both the door and frame, but in some instances this isn’t feasible so we can fit a new door into an existing frame. With any new doors we can replicate period design features, and offer colour matching. 

How do I order Banham keys?

You can order new keys in person from one of our showrooms. We cut every key to order, and our Key Registration service means that we will only copy our patent protected Mark III key with your permission. To find your nearest location, visit our showroom page.
