I had Avocet cylinders for the front and back doors. We've since replaced a lot of downstairs doors with modern ones (UPVC or aluminium); all with euro cylinders. That means six sets of keys.
I remember reading how the Avocet keys could be easily bypassed or overridden. There are companies that do keyed alike but are any particularly reliable ones?
