Company profile

Pickersgill-Kaye was formed in 1855 by Joseph Kaye as a small engineering concern involved primarily with the manufacture of oil cans. During the latter part of the 19th century the company continued to diversify and eventually specialised in the design and manufacture of Kaye’s patent door locks supplying the architectural and railway industries throughout the UK. In October 2015, Pickersgill-Kaye became part of the Assa Abloy Group of companies.
