Build a terraced end house with an additional unit (GÜ) on your own

Hello,
We also have an automatic lock and it is great. Next to the door, there is a part where you hold a chip to open it. I didn’t want a fingerprint scanner because I have to wear gloves a lot at work and it probably wouldn’t always work. We still have keys on the key ring. My parents often take the dog for a walk and think it’s a good idea to lock it additionally with the key from time to time. Then we can only open our door again with the key...

Then you must not forget the key

I would have liked the thing with the chip too - well, the topic is closed, we won't be buying a new front door anytime soon..

What happens during a power outage?

Power outage? Simply give the key to the neighbor or hide it, done.

Exactly. In case of a power outage or false rejection, only a security loophole helps, otherwise you always have to carry a toothbrush and a credit card. I prefer to use the old-fashioned key.

With good scanners, it’s not the fingerprint that is scanned but, for example, the veins underneath. Additionally, there is a liveness detection. The normal lock in the door is still easier to attack. I wouldn’t want to give that up either.

A good solution would be a combination of such a scanner with liveness detection, an (RFID) chip card reader, and a classic hardware key as two-factor authorization (two out of three must be used); then I would see a security gain in it.

how the insurance evaluates such a lock

That’s a good question. Are there automatic locks and scanners with intrusion event loggers, or will no one believe the break-in because such high-tech is hardly tamperable? I live, by the way, in a multi-family house. If we see a neighbor arriving from the window with heavy shopping bags, we go to the door handle. For that I would need an intelligent technology in a single-family house!

Always interesting how individual it is. We want our next front door specifically so that it can be adjusted to open only with pressure and that it is not immediately closed when it swings shut. When we are in the garden or have guests, of course only so that not everyone always has to go through the open back entrance, but the front entrance doesn’t have to be left open either. This has always been somewhat annoying, especially at bigger parties. Personally, I’m always for less frills, I wouldn’t think all this is worth the extra cost.

Isn't there usually a latch on the door frame where the lock snaps in? If you flip it, the door doesn't close when it falls shut.

Yes, that exists, but our door from the 90s does not have that. The next door must have it, but I actually don’t need more comfort in a front door.
