URGENT Thumb turn cylinder lock on door question

(31 Posts)

I'm moving to a new house (rented from family member) and he's put a new door in which features this type of lock; you lift the handle and turn the lock by hand to lock it from the inside, but you need a key to lock it/open it from the outside.

If I was to lock it from the inside, would somebody with a key be able to open it from the outside, even if it it locked on the inside?

Reason I ask is because this family member has poor boundaries and I made it quite clear to him that I dont want him just letting himself into my home when he feels like it. I said I would just put the key all the way through the lock so he wouldnt be able to open it from the outside, but he has gone and put this type of lock on the door and i'm wondering if he is doing this so he can let himself into my home?

Yes they would

Do you have an extra lock or bolt?

I have the 'holiday' lock as well

MrsHathaway Tue 06-Feb-18 20:00:29

We have one.

Yes you would be able to open with a key outside if someone had used the thumb turn inside. I lock the door when we get in from school; DH uses his key to open it when he gets home.

You'd want a chain, deadbolt etc as well to be sure boundaries are maintained.

Chains etc only help keep him out when you’re at home.

If you want to ensure he won’t come in without your permission then you need a different lock.

I wouldn't rent from this person tho

Thanks all. I'm fucking gutted, i'll have to stay in this freezing cold flat then. I'm gutted

Just put a chain on.

Tobythecat Tue 06-Feb-18 20:07:47

he wont let me put a chain on

Change the lock on arrival . return it when you leave.

I take it this place is cheap for a reason?

He sounds dangerous.

Just change the lock. Costs less than a tenner

These types of lock are common for fire doors in flats- replacing them would cost a fortune. The only way to stop him would be to put chain on but that won’t stop the issue of him trying to enter your flat without your permission.

I wouldn't be comfortable with that. Fine when you're in the house but you say they won't allow a chain? Nope, I wouldn't sleep soundly (I've got 3 locks on front door)

If you do take the place, get some Door wedges [novelty is fun] kick them in firmly so no one can open the doors inwards. If you need to leave, just jump out the window [optional 🤗🤣]

if its a euro lock then as someone has said you can just swap the cylinder relatively cheaply.

I've found the backs of our dining chairs wedge nicely under the handle which would stop anyone getting in even if they had a key. This only works when you are at home though.

If I was to lock it from the inside, would somebody with a key be able to open it from the outside, even if it it locked on the inside?

Yes if you remove the key, no if you leave the key in. I leave my key in partly for that reason but also in case of fire or other emergency, I'm not hunting for a key.

If I leave a key on the inside of our lock, no one unlock it from the outside.
I’m not sure it’s the same lock, but worth an experiment.
You can explain it away as fire safety ( that’s why we leave our key there).

Kitsharrington Wed 07-Feb-18 07:38:49

I’m pretty sure if you leave the key in the lock no one can get the key in from the outside.

Read the title - its "Thumb turn cylinder lock". You don't use a key inside.

AngeloMysterioso Wed 07-Feb-18 07:51:21

If you mean this type of lock OP, unless you have a second lock or a chain etc then yes, anyone with a key can get in.

AngeloMysterioso Wed 07-Feb-18 07:53:53

Try again with photos...

brownelephant Wed 07-Feb-18 07:57:45

either you

- put up with it
- change the locks (just the cylinder, it's easy to do yourself with a youtube tutorial)
- don't rent from the person

if you go ahead, read up on tennancy rights. they cannot just enter another person's home without permission.

I assume it will be a ast with deposit & contract?

The door wedge idea is brilliant. A few of them under one door, there's no way he'd get in.

Flomy Wed 07-Feb-18 08:05:59

You dont want him snooping around when you are out either.

MrsHathaway Wed 07-Feb-18 08:12:50

The wider point is that OP doesn't trust this person to afford her quiet enjoyment and couldn't keep him out (whether she was at home or not) so is probably best advised to decline his offer.

Hope you find a suitable alternative very soon flowers
