Yale

Real & fantasy workspaces must be Covid- & physically-safe: even Dr Who uses a Yale-type key to open the Tardis.  1861 Linus Yale, whose family went from Wales to New York, patented a pin-tumbler mechanism, based on ancient Egypt’s wood locks.  His light, small brass keys made locks available to all, for the 1st time.  Today’s Yale key is similar to the original.  The firm now pioneers keyless smart systems.  Design classic, still secure at the top of lock-making
