Front door 5-point or 3-point automatic locking?

Thank you for your answers

I just wanted to know if there are any disadvantages to the [3fach Automatikverriegelung]?

If I have overlooked this, I apologize.

And with the [3fach Automatikverriegelung], can you definitely retrofit a different lock cylinder and a Nuki lock?

The disadvantage is that it is then automatically locked. In such a way that the locksmith can no longer get in without causing damage if you lock yourself out.

Ok, that is not so negative for me, a spare key will be stored elsewhere with my parents and parents-in-law for emergencies

If there is nothing else negative, we will take them

And in such a way that the locksmith can no longer enter without damage if you accidentally lock yourself out

By the way, that's nonsense. They can, they just prefer to sell you a new locking system.

Really? Until now, I also thought it would be expensive with automatic doors if I’m locked out without a key.

It does happen, but only because locksmiths almost exclusively use heavy-duty tools, even though they could simply use a lock pick. This works even with so-called security cylinders (but not with all), but definitely with normal locking cylinders. Of course, the tamper protection must be destroyed, but the cylinder can almost always be "cracked." I witnessed it live once myself. Burglars don’t do it this way because it takes longer than the famous three to five minutes.
