Fitted an old lock where the keys had been lost. Very little adjustment to the existing recess was required, and the keys fitted without further difficulty. The biggest problem was in finding Legge locks in retail outlets as the market appears to be dominated by 2 major players, certainly in the large supermarkets like B and Q, Wickes etc. Even Robert Dyas and my local lock smith shop did not stock them. I looked around on the Internet and found the right piece of merchandise. However, checking sizes of the recess, existing lock was necessary. By having a retail outlet I could have reassured myself that the lock was the correct model.

Liked the keyed alike feature available for this lock. It saved buying extra keys although it does diminish the security for the door by having the two locks keyed alike.
