Euro lock cylinder question

I'm not sure such a thing exists. If you're happy to leave a key in the lock on the inside, why not just replace it with a thumb wheel actuated lock?

That way it can be locked from the inside but unlocked from the outside with a key.

Tim

OK so are you sure that a lock secured from the inside with such a button can be opened with a key from the outside? I'm not saying they cannot but want to be sure before buying one.

Bob

It's not a button, it's a thumb wheel that replaces the key on one side.

e.g.

And yes, you can unlock it with a key from the outside when locked.

Tim

They do exist but I haven't a clue what they are called. They were being advertised as suitable for the infirm last time I bought some standard ones.

With some, a key in side A blocks key action on side B & vice versa. With some it doesn't. I'd go to a shop & try one.

If you go for a thumbscrew type and your door has a letter opening anywhere near the lock then get a security cover for the letter opening on the inside.

Yes you can:

New ABUS E60 Series Euro Double NP Cylinder with 8 drill protection pins in every keyway

The E60 range has the new emergency & convenience feature where outside key operates lock even with the internal key in place. This means you will not get locked out if you leave a key on the inside (as long as you have a key to use from outside)

They can. We have three of them (all taking the same key) they are preferable by the fire service.

I've just been measuring my door lock thickness and from what I can tell a key in both sides would not work, it would just part push out the key on the other side and wedge the lock.

This is what used to happen in days of yore of course, hence I suspect the gadget you mention was invented. Brian

Good point generally but this is our back door to the garden so full length glazed and no letter plate.

Excellent! thank you

"Emergency" and "convenience" seem to be the search terms
