Does this kind of lock exist?

[703810995]

Hello.

I'm looking for a lock that takes the quickest time to open and close, so I'm guessing something like the keyhole side of a night-latch on both sides that only requires a quarter turn of the key to open (not a knob/handle/thumb turn on one side like normal night latches) and just a pull of the door to lock it with no key required. Does this or something similar exist?

Thank you.

You can have it so it can only operate on one side.

No, as stated, it needs to be something that needs a key to open on both sides and also be secure on both sides, i.e. not be able to simply unscrew the mechanism from one side or the other.

I assume from the lack of replies that a two-sided automatic closing spring-lock doesn't exist, so looks like I will have to settle for a non-spring lock.

Does a two way cam-lock exist, like in the image in the link below?

This would be the next quickest solution as, although it would require the key to lock the door, it only requires a quarter turn.

If even this doesn't exist, then maybe a mortice deadlock/euro profile cylinder setup, but the edge of the door is only 25cm wide?

Found the one below, but it's not 'cheap'!

My door will lock without the key if that's what you mean? if I go out and pull the door it will be locked, and I will need the key to get back in.

 

[703810995]

Catlad, yes, but as mentioned, it needs to require the key to open it from both sides, not just one side because both sides are external. There is no 'internal' side, so apart from needing a key on both sides, it need to be secure on both side too. I have seen night latches that have a Yale type keyhole on one side and another keyhole on the actual handle on the other side, but this is also the 'internal' side of the lock and can be unscrewed.

1- So what lock is on there now?
2- Confused as how both sides can be external, is this an outside security door/gate?
3- Unless the lock is installed within the door rather than surface mounted, I fail to see how you could reasonably expect it not to be removable!
4- Pictures

1 - Latch.
2 - Outdoor door/gate.
3 - Those are my thoughts too but I think there might need to be some welding involved for some part of it.
4 - Same as the picture in the last link in post no. 3 above.

It doesn't have to mega secure, just not easily dismantled from either side. Something as simple as the cam lock (first link in post no. 3) would suffice, but am not sure if anything similar is available with a lock on both sides. Speed of operation is priority, hence my questions about a two-way night latch, i.e. would only need a key to open and can just be pulled shut.

Thank you for the reply.

Mine has a key on both sides.

I think you mean a locking latch, operated by key from both sides.

I have a few examples, they are all mortice locks so there is no exposed case. Can you fit a mortice lock? How thick is the gate?

Look at a Chubb 3R35 to see how it works (can be fitted without handle action) though that is a particularly expensive one, frequently found on banks that still have wooden doors.

Yes it does.

A cheaper one is the Union HD72.

It is a mortice nightlatch. It latches and locks automatically when closed.
Usually, it is fitted with a keyhole on both sides, and a handle on the inside. Either will open it.
In your case, you simply fit it with a keyhole on both sides, and no handle.

It is a Eurocylinder lock. If, like me, you prefer lever locks, I can supply one.

Sorry I didn't know there were more replies since my last post!

Since my last post, I bought a lever deadlock, but it hasn't been installed yet so will go over the new suggestions posted above and reply soon.

I think you mean a locking latch, operated by key from both sides.

Are the comments above referring to the same type of lock and if so, is it the type pictured in post #12? If so, that one seems to need a handle, which I definitely don't want. I did a quick search for 'locking latch' but didn't find anything relevant.

I also searched Chubb 3R35 and couldn't find an example of a handle-less version and in any case, they do seem to be quite expensive.

Is a 'security' screw just the same as a normal screw but with an uncommon head that can be easily removed by a cheap tool bought online? I did come across these latches during my search, but can't remember why I dismissed them now. Maybe I was unsure if the 70mm thickness of the door was just a recommendation or a requirement. I would assume a recommendation and the only issue would be that the barrel would just be sticking out quite a bit (the gate is only 25mm thick). This option would have to be welded, but is definitely a consideration if the above 'locking latch' is too expensive.

A cheaper one is the Union HD72.

This also sounds a viable option.

In your case, you simply fit it with a keyhole on both sides, and no handle.

If I fit it without a handle, will it still lock when the gate is closed without a key? The PDF linked to says the below.

Cylinder to latch functionality.

Deadlocking Nighlatch function from the inside:
Latch bolt withdrawn by either the lever handle or the
cylinder key/turn
When the door closes and the snib comes into contact
with the strike the latch is deadlocked

Deadlocking Nightlatch function from the outside:
Latch bolt withdrawn by the cylinder key to unlock the
door
When the door closes and the snib comes into contact
with the strike the latch is deadlocked and a key must
be used for reentry

If I do decide to go ahead with the mortice deadlock I bought, would using screws/bolts with a nylon washer nut for the plate be a suitable option or are there any better ideas? It doesn't need a special box or case, a simple metal plate screwed/welded at the front and back would do the job. The gate is about 25mm wide, but the lock is only about 12mm, so I think would be suitable.

Ideally, I would like to be able to replace the lock easily if/when it fails. Obviously, anything involving welding will make this difficult but I don't mind having to unscrew a mortice lock. I would assume a Euro cylinder would be easiest.

Can you fit a mortice lock?

I can fit one but would have to hire somebody to cut/drill the metal gate.

Thank you for all the advice.
