All about Scandinavian locks

While Scandinavian multi-point locking mechanisms are not very common in Norfolk, there are enough of them to warrant a mention.

The locks look something like this :

These locks operate with a mechanism that typically employs two hooks that come out from the door and fit into specially cut spaces within the door frame, just like many upvc doors. They are always fitted to wooden doors, which is where the problems start.

In Scandinavian countries they are geared up for cold, damp weather and treat woods accordingly. Here in the UK, we seem to use any wood going and think a coat of paint or varnish will be adequate. That works okay for standard locks where all the working parts are protected within a lock case, but locking mechanisms have exposed moving parts which get pinched and moved by doors that expand and contract in wet weather. The untreated inside of UK doors holds water like a sponge, right next to the metal of these mechanisms which quickly become prone to rust. The problem is compounded by the fact that there used to be several variants of these mechanisms available, but now all but one design have been discontinued, meaning that if your mechanism does go wrong, the replacement is likely to be different. An example being a job I have recently done where everything looked identical, but the door needed much chisel work to accept the replacement.

The next problem is cost. These units are extremely expensive.  A complete set up can cost between £250 and £400 depending on who you use to fit the device with labour and VAT to be added to that figure.

Finally, these locks are not particularly secure. While many insurance companies will accept them as adequate, they do not get the British Standard 3621 rating I would recommend to feel properly protected.

If you think you might have Scandinavian locks and they have not been serviced recently, it might well be worth contacting your local locksmith to have a look at them, especially if they are hard to lock, or the handles have gone floppy. A little maintenance now, might save a lot of cost later, or at least alert you to the likely cost of replacement, rather than have it all come as a shock when you can least afford it.
