Ehh, they sell models with no keyhole now. At least youre trading risks at that point.

Or in my case, the entire front door is made of glass...

Here in belgium our doors sacrifice everything in the name of marginally more security: fire safety, failure modes & maintainability, convenience, and protection from user error.

• Each modern door has 2+ deadbolts + hooks, many times a strike plate that is a bit bit more crowbar resistant, etc... but the mechanism is all tied to the handle so you can't lock the door if the handle sticks because of lack of maintenance or -10C weather. This also is about 1500€ to replace if you break it trying to lock your door when it is sticking.

• Many doors have no front handle, so if you leave your keys inside (even if you are just running to get the mail), you are locked out. If someone leaves the keys on the inside of the eurocylinder, you can't unlock it from the outside unless you bump the keys out which isn't too easy for someone who only has a key.

• Finally, almost no doors nowadays have a deadbolt dials on the inside, so you have to lock it from inside with keys. This means that both someone who steals a key can lock you inside (see point 2) and also it is a huge fire hazard because you can't open the door from the inside without a key. You either have to hope that you aren't too blind and dazed from smoke during a fire to find the keys, get them in the lock, and get outside, or leave the keys in the lock and completely negate the security benefit of having no deadbolt dial + the added inconvenience of another person living there unable to get inside if they come home later.

Then, on my door and many other modern doors here the security that they sacrifice so much functionality for is negated in any case because there is a 60x180cm double glass pane that they can simply break through. It is literally the worst system I have ever come across lol

Technically, some criminals will see it and pass on the house assuming there is an alarm system. The failure modes is a good point though.
