Security key at the front door, yes or no?

Have you decided on a security key for the front door or side entrance door? Or did you take a normal standard key?

What do you mean by "security key"? - Security lock with profile cylinder has been standard forever, no one has used a bit key lock newly since my kindergarten days.

Profile cylinder is by far not standard! I asked around in our circle of acquaintances and our neighborhood. 90% of the people have simple cylinder keys.

If neighbors can be broken into so easily, you have nothing to fear. You also don’t have to run faster than a hungry lion if your neighbor is slower than you.

I would be interested in a statistic showing how many burglaries happen through the front door. The weak points are probably somewhere else. I'm curious when the first ones will break in through [Porenbeton], instead of through the secured windows and doors.

I had to laugh just now when I read about the aerated concrete

Theoretically, we wouldn't even need to lock our front door...

At least not if our guard is in the house

Good question!
Burglars break in where it is easiest. Classics are balcony doors, tilted windows, basement windows. Front doors can also be opened very quickly with the wrong lock - whether with a lock pick (cheap cylinder) or by "pulling" the cylinder, which then breaks at the narrowest point (no pull protection). Breaking windows is also a popular method but tends to be too loud. Glass cutters are also used, but then by professionals who carefully choose their targets.
In Cologne, there is a master lockpicker who offers door openings on the side for a small fee and opens over 90% of locks without damage.
