Simple house refurb, needs half-a-dozen or so keyed-alike external locks. Doesn't need mastering, alike is adequate (though even that's regarded as impractical voodoo by most of the UK). BS 3621 is probably going to be required by the insurers though. Doors are Victorian woodwork, not modern UPVC or three-point systems that would mandate a Euro cylinder.
What would the panel suggest as a keyway / brand to fit? Simple 5- lever mortices all round, or some design more modern? Euro cylinders, or something less common (and thus more expensive / possibly harder to support in the future).
Thanks
