UPVC Door Security

[Jamp]

I've just got a new place which has 3 external UPVC doors. Long term I would like to replace with timber, but in the meantime I'd like to replace the locks with snap and bump proof euro cylinders. Ideally I'd go for 3 keyed alike to minimise keys and confusion. They seem to often come in keyed alike pairs though, so one pair and one single would do.

What is folks' experience/point of view with regard to thumbturns on the inside? It sounds like a good idea for escape/ease of use, but perhaps less than clever when all the doors are part glazed? Any alternative options for over night security but with ease of escape, without using the main lock?

Any advice on which locks to go for and any good online suppliers?

Im considering one of these to improve my French door security.

I bought Avocet ABS from here, as many as you want can be keyed alike.

Upgrading the handles to solid hoppe ones will be the first upgrade I would make. Lock snapping only occurs when they have managed to snap the handle first.

Also if your back door is upvc with a plastic lower panel that's vulnerable with a bit of a kick, remove the beading and silicone the grooves before putting panel back.

AS above - Hoppe handles with PAS24 certification, and Avocet ABS cylinders.
Not cheap, but the only way in will then be to smash glass or go through the roof. If they want in, they will get in - it's just a case of slowing them down or making them reconsider.
If you have more than one entry point might be worth considering single-sided locks with just a keyhole on the inside - I've fitted these to my rear entrances (ahem) so there is literally nowhere on the external side to put a key, never mind try and force the lock.
