Description Key4B “Bramah” Key. Bramah Keys and locks were invented by Joseph Bramah in 1784. The company is still in business making high security low-volume locks in Britian. We believe our keys range from the mid 19th century to the early 20 century. Advertised as the first “unpickable” lock, it was finally defeated after 70 years, and took the person who picked it 16 days! Sold by the each, photo is a representative sample only showing the various sizes and configurations that Bramah keys come in.
