Pro and cons of thumb turn eurocylinder locks

[PositronicRay]

We have 2 x 1/2 glazed multi pane back doors, one kitchen and one boot/utility room.

Pros
Can open with key from outside if locked from the inside.
Can get out in hurry
Less fannying around with keys so more likely to lock

Cons
Thief can smash small double glazed glass panel and let themselves in.

Anything I've missed? (looking to upgrade the locks)

[Evanivitch]

Personally I think the benefit of being able to leave the property in an emergency outweighs the cons.

Our front door is thumbturn, and the letter box is blanked and the glass is laminated. It would take some effort to get through.

The first thing burglars do on entry is secure an exit incase they get disturbed, if they can't they won't hang around as long.

Well if they're already inside...

The Avocet ABS thumbturn renders the external key lock inoperable if the thumbturn is left 'engaged' or half turned. Not a big issue for a rear door, but on our front door it has caught me out a few times as we have a pad handle so need a key to open once it is pulled shut.

It's quite hard to smash a double-glazed window.

But, if someone is prepared to try and smash a dbl-glazed window to get in, then they are not 'subtle' burglars. Even if the back door couldn't be unlocked via a key, they would smash another window they could climb through.
In other words, if you're prepared to smash a window, you'll smash any window to get in - not just because it's got a convenient lock on the inside.

But if that's the only likely entry point, and the window can't be climbed through when broken, then you might be better off with a key lock

I'm with you on this, once round the back and smashing things, game over. Mrs Ray thinks the thumb turn makes us more venerable.
A neighbour was broken into 6 months ago, round the back and lobbed something through the kitchen window.

Thinking about it if broken windows are to be used as a main point of entry is there any point to anti bump locks?

He means if someone climbs through a broken window they will like to find a thumb turn so they can unlock and have a means of easy escape.
It’s not as easy or quick to run off with a 40” telly through the window you just climbed through.

Do people still steal tellies?

[Rosscow]

I’d rather they undid a thumb turn and walked out instead of more damage!!!

That's a fair point, but I'd rather mitigate that by stopping them getting in in the first place and trade that against being able to exit quickly in an emergency.

For emergencies we've for a spare key tucked under the edge of the carpet in front of the door. Just a habit because my dad used to do the same thing when I was a kid.

We've also got Cisa Astral cylinders, specifically because they still work if a key is still in the lock inside.

[Sgt Bilko]

With an easily obtained piece of kit, thumb turns can be silently opened in around 3-4 seconds. There are some higher priced ones have overcome the problem that exists on the lower models but it’s the same issue that was discovered when “bump” keys started to float around.

Oh the joys of living in a nice area without having to lock ones doors.

Cisa Astral maybe the best of both worlds

I've an idea how these bump keys work, no idea re the thumb turn thing? How does that work?

This would be ideal. However in the UK, for someone less than 45mins from a town, even a 'nice' one you're at risk.

(I made up the 45min thing but you get my drift)

Don’t wish to sound rude or evasive, but that’s not something I can share as it was training through work. I say training, more like a two minute demo and practise.

Is that true of all thumb turns or cheaper models?
