Outbreak prevention

We have not bought this lock to start prophylaxis, but to prevent our son for the outbreak.
Consideration:
-The Door should be able to be locked without one it is flush with the key. In the event of a fire, only one button is to be turned, not a key must be sought only in the worst case.
-The Door should despite internal latch can be closed from the outside, so that no one who comes home late yet to ring.

First, my husband bought another castle at our key Fritzen (though that was there more expensive than the Abus at Amazon .... ^^), which, however, was processed very hakelig and bad.
So then but the Abus: (Fortunately, the Abus lock from covering the holes of the previous!)

To start prophylaxis in anchoring in the brickwork it is certainly. The installation succeeded easily, the lock closes smoothly. Visually, it fits for a foreign body discreetly.
Buy recommendation.
