Chubb Yale Window Lock Keys 8K101K Twin Pack

I’d look in very large and small ironmongery type shop and none of them sold these window locks. I have them on all my windows and have lost some over the years so I was very pleased to find them online. They are 5 sided and fit perfectly. I’ve just ordered another couple for spares.

Excellent quick delivery of items as described. Keys have a hexagonal cross section which fits old Chubb window locks.

Bought extra keys to have beside each window, fit, work, secure.

They fit my window locks well; amazed l could get them as the lock are 25 years old!

20 year old wicks conservatory fitted perfectly delivered on time .

Size (in mm or inches, cross-flats) not provided in description. When received, found that they were too small and wouldn't work. Same problem with other suppliers. No one makes clear whether stated dimensions are width at widest point or instead cross-flats (the classic standard measurement). Very, very frustrating.

I didn't know you could get spares of these, which are now distributed around the house. Inexpensive and delivered quickly - what more could you ask?
