Hi all,

I've just bought a new oak front door and am thinking about security combined with looks but have hit some confusion about locks.

I'd rather go with a multi point lock over a standard Yale lock for security & insurance reasons but I dont want a handle on the outside; all I want is a long pull handle on the outside with just a key hole visible.

On the inside I dont mind having a traditional lever handle, so could I get away with a lever/pad lock and only install the inside handle? This would be less secure though when I'm out the house as I can only engage the additional hooks/rollers from inside?

Yale have reference to a key wind lock on their website but I can't see this anywhere to buy.

Any help is appreciated.

Thanks

Thanks for your reply, its nice to know I don't really need a multi point on a timber door.

In that case then, is there such a lock that Is operated by key only on the outside and either key only or key and lever inside, but not a night latch as I want it to be aesthetically pleasing.

Thanks.
 
yes, there are some, but I don't think any meet the current BS for thief-resisting locks, which your insurers probably require. Apart from deadlock length (if any), a burglar can open the door after he has gained entry through a window, or has reached through the letterbox, or broken or cut a hole in glass or door panel.

They are usually referred to as Mortice Nightlatches.

Or you could fit a Eurocylinder deadlock which has a thumbturn (rather than a cylinder) on the inside.

There is also the Union (formerly Chubb) 3R35, and the obsolescent Union (formerly Wellington) J-4GB, both of which are often available cheap on ebay as stock clearance because they do not meet the BS.

The 3R35 allows you to deadlock it with a key so that the handle is inoperative.

Insurers usually allow people in flats, where there is only one exit, to have a lock that can always be opened with a knob or handle, to save searching for a key in case of fire.

Another approach is to have a nightlatch, which can be a mortice nightlatch, at the top third of the door, and a mortice deadlock at the bottom third of a door, suited to the same key, which is very convenient, and having a BS deadlock will satisfy your insurers. This makes a very secure installation, except that householders tend to get into the lazy habit of only using the nightlatch.

If you were willing to accept a surface-mounted (rim) nightlatch, it would be much easier. They are available to meet the BS. You could have a mortice deadlock as well.

Thanks for your help on al lthis, I jsut want to get the right one (that is secure!)

So the operation I'm after is:
Latch so when I pull the door closed it's only openable with a key
Deadlock so I can secure the door further.

Looks I'm after are:
One key only outside
Handle or one key only inside

In my head I'm looking for something that looks like this, but the key can have an extra half turn (after opening the deadbolt) to throw the latch from either side?

Or alternatively exactly the same as the above, only with the option of putting a handle only on the inside to throw the latch?

Would this combination work as described above?

no.

these would

but I don't think any meet BS. But you could add a BS deadlock suited to the same key, and put it on the door as well.

the 3R35 has deadlocking by key and is a very fine lock

Most peoplw would go for a BS deadlock and a (preferably) BS night;atch. But you would have to accept a surface-mounted nightlatch unless you think a non-BS nightlatch would do.

It's possible that the specialist (=expensive) makers like Banham or Bramah could help.

AFAIK there is not even an Ingersoll London Line lock that does what you want.
