Does such a lock exist?

[Traveller]

Hi all.

I am looking for a lock for a normal width internal bedroom door (35mm) that can be locked from both sides, either both sides need a key or the inside could have a thumb turn. I would also prefer it to use a Yale type key and not one of these. I do not want a Yale type lock due to the annoyance of closing the door with the key inside!

Does such a lock exist? If so, what is it called?

My research has thrown up 'single cylinder deadbolt lock'. Are these available for doors that are 35mm thick?

I have also found 'thumbturn Euro cylinder', but is it correct that these are not available for doors that are 35mm thick?

Thanks.

How far may a euro cylinder stick out of your door before you're unhappy with the finish/end result?

I'm not sure, but I don't think that much. What is the smallest available?

30/30 and upwards at 5mm increments is the smallest I've seen but a Google shows you can go as small as 20/20 though not with a thumb turn.

If your door is 35mm, half that = 17mm plus the thickness of the handle back plate of say 10mm ish = 27mm so a 30/30 should be fine

Thanks, looks like something like that would be suitable. Both replies relate to a euro cylinder, is a single cylinder deadbolt lock unsuitable for any reason?

Sorry I misunderstood, having googled the lock then I'd say it would most defo be suitable, from the ones I saw they said 35mm to 50mm thick doors

You need a thumbturn on the inside so the occupants can escape in an emergency, or if locked in accidentally or maliciously.

Combination lock?

You need a thumbturn on the inside so the occupants can escape in an emergency, or if locked in accidentally or maliciously.

Why? Is there a law that says you can't have locks on internal doors or ones that require thumbturns?

Agreed, irrespective of what any applicable regs may exist.

I too agree. I had a friend that lived in an HMO temporarily. She, exited the flat that she was renting, got to the main door to exit the property, and realised she had left her keys in the flat. Without her keys she was unable to exit the building because the door into the property had a chub type lock. She had to wait 5 hours in the hallway until someone entered, enabling her to leave.

But she was warm and dry for those five hours-has she been able to get out of the thumb turn then she'd be locked outside without her keys in the cold and wet for five hours so it might have worked in her favour there?

Imprisonment is not usually considered a benefit.
