Burglary protection - Upgrade windows from WK2 to WK3 - Alarm system?

How do you actually practice using lockable handles? Do you always lock them, take the key out, and then store it (where?) until the window or door is to be opened again?

That's how it is
The key is stored within immediate reach, for example on a dresser, but without direct line of sight to it.

On the ground floor, the windows are always locked, upstairs only when we are away from the house for a longer period. We have then distributed the keys in various places in the house.

How do you actually handle the lockable handles?

The trick is controlled ventilation. We usually don’t need to open most of the windows on the ground floor anyway, so all keys are stored centrally right next to the patio door (in a drawer). Upstairs, the keys are simply left in the lock.

The trick is controlled ventilation and exhaust. We don't really need to open most windows on the ground floor anyway, so all keys are stored centrally right next to the patio door (in a drawer). On the upper floor, the keys are simply left in the lock.

Then you could also just have fixed-glass windows on the ground floor? If you don't open them anyway, you might as well skip the handles altogether.

I opened this thread specifically related to my house... of course the general information here can also help, but we have a "block" of 6 houses, all built between 2009 and 2011. All with the same companies and definitely all with the same window manufacturer.

However, there are relatively large differences in window security. Everything from basic security up to WK3 is present. However, all windows (according to the window manufacturer) are made from the same profiles, whether basic or WK3.

Here I can of course only rely on his information.

These have so-called panic locks, i.e. even when the hut is locked, if you press the interior handle from the inside, the door opens.

For this reason I have an anti-panic lock... meaning if it’s locked, then it’s locked...

That means all keys fit each other. Even if one should be lost...

So I consider losing a key very unlikely, because you usually don’t take them out of the house, why would you? And if it gets lost in the house, then so be it...

The easier way is to get the keys on the market by simply buying one/two/three handles in the trade, then you already have the most common locks available... absolute security doesn’t exist... but a lockable handle at least delays until you have found the right key, inserted it into the lock and then turned it... those seconds can be crucial.

lockable handles with alarm function.

Personally, I consider the alarm function more like a toy... but that’s just my opinion.

Yes, of course, what else would be the point of the handles? Then you might as well install the simple ones if the key remains in the lock.

then also through the terrace door (WK3), but here the roller shutter was torn off and the triple glazing was smashed.

WK3 would mean laminated safety glass. Even P5A instead of P4A (WK2). Was it really like that? It must have taken forever to smash a hole big enough to climb through.

So for us it is planned/available:
- everywhere RC2, meaning mushroom cams, laminated safety glass, lockable handles
- window contact switches wired in a star so that each window can be monitored for open/closed/tilted
- LAN laid to the front door and terrace door for video surveillance
- later setup of an alarm system based on the window contact switches with external siren and GSM module / SIM card, so that an SMS is sent when triggered

Lockable olives already bring something combined with laminated safety glass. You first have to laboriously smash the glass until your arm fits through and then the handle is locked at first and you need a bigger hole in the glass to have enough freedom of movement to attack the handle accordingly.
