5 lever locks cannot, due to BS3621:2004 quality standards, be as freely offered in keyed alike sets as the 2 or 3 lever options. The best that can be achieved is up to 6 locks of a type, for instance up to 6 x 77mm brass deadlocks, keyed alike
Unfortunately we cannot supply keyed alike across deadlocks and sashlocks sizes or finishes
Keyed Alike means that all the deadlocks can be opened using the same key number
