Our old door used to have a Yale lock (as a precaution left a key with our neighbour in case I ever locked my myself out), replaced the door though 6 months ago to a composite with a traditional multi point lock on that doesn't auto lock you out.
Autolock with a key safe outside. Honestly, for £20 I get security and peace of mind (I can't lock myself out). Seems a no-brainer to me.
Ours locks automatically but we still lock it with a key, it makes it behave slightly differently when you do (iirc the handle can no longer be turned downwards).
Probably completely unnecessary but hey-ho.
Putting a brick through your Bifolds is much quicker - plus how do they know its on a thumb-turn from the outside??If it's the type with a thumb lock on the inside, aren't those generally bad as they can be (relatively) easily broken into, I.e. burgler just has to turn it from the outside via broken window for example.
I have to lock mine. I wouldn’t want one that self locked as I’d no doubt lock myself out.

Done this. Put the bin-bag out to the wheelie bin, in my socks, and the door closed behind me.
I had to walk to the other side of town to get a spare key from my mum![]()


Standard multi point lock in the front, automatic locking would be a right PITA.
Someone I know put in a UPVC door that locked automatically, had a lock smith out 3 times in the first year and were locked out more times than that. Twice when taking rubbish out and the door blew shut, no phone or coat and it was winter. I guess it worked…!



This is my main worry with a door you need to manually lock. What do you guys do when inside your house? Constantly have the door locked from the inside? What a painI also can't imagine being comfortable or relaxed in my own house knowing that any delivery driver, leaflet dropper or other random joe could just let themselves in, even if that is thoroughly unlikely and an irrational worry.
