uPVC Door Locks - Euro Cylinder quality

[littlerichley]

I have two elderly (20 year old) double glazed doors whose euro-cylinder locks I want to replace with modern units of good quality.

I have had a search of this forum and found reference to BS3621:2004 in a post and wondered if this applied to euro-cylinder devices? The only mentions to standards I have seen regarding euro-cylinders refers to BS EN 1303.

One of the locks appears now to be broken (key turns less than 45 degrees in each direction) and I was wondering what I should specify as a replacement? Retail prices seem to vary from £5 to £50.

Thanks.

Take a look at http://www.locksmiths.co.uk/homeSecurity/default.asp for general advice. If the doors are old, then this is likely to be the weak point - not the cylinder. Purchasing expensive cylinders is only worthwhile if you've a solid door and frame, and security escutcheon to compliment it.
