Electronic front door with fingerprint entrance

Then just take out the service, order the front door with fingerprint online, and have your carpenter install it for 400€! You just have to tell your general contractor where the screed should be stopped and where the wiring needs to go, because after that it won’t matter to him. Such a system is already quite expensive online and costs 1200€ from my front door manufacturer (without door and without installation).

As a fairly universal solution, you can browse at ekey, there you can get a feel for the technology. However, most door manufacturers sell their own technology. Fingerprint and motor lock definitely come at an additional cost of around €1000.

Motor lock +1,000 - 1,300€ Ekey with control unit etc +850€

Thank you for your response. I did some research today on the ekey website. The following components can be seen: 1 Connection cable detection unit-control unit 2 Power supply 3 Detection unit (finger scanner or code keypad) 4 Control unit 5 E-distributor 6 Motor lock 7 Cable transition 8 Connection cable control unit-motor lock

I'll throw the door lock system from Homematic into the ring. The whole system is visible, but the option of a normal lock remains. The whole thing works with a biokey fingerprint sensor and voilà, the setup is done. I want to install something like that myself as well. However, it is a radio system, no idea if that suits you.

I am currently dealing with this topic as well and maybe it will help you.

It would also be important to know whether you want to use KNX, that is, a bus system. I don’t think so, but it doesn’t hurt to ask. Therefore, I assume that the fingerprint is intended as a standalone solution.

First, talk to your general contractor, because anyone who doesn’t offer a door with fingerprint today is living behind the times. The window manufacturer, general contractor, etc. usually buy the doors. Often from Schüco, and the manufacturers offer this. I am 100% sure that you will get it, so just a bit of info.

The additional cost is about €1,000–1,300 because it’s not done with the fingerprint alone (I recommend ekey). The door needs a mechanical lock because what happens if you lock the door with a key? You cannot open it with the fingerprint because it is locked. The advantage of a mechanical lock is also that the door ALWAYS locks when it falls into the lock. If you then authorize yourself from the outside with your finger, a motor opens the lock. The locking mechanism is released when you press down the door handle.

Have a door like this shown to you, then you will quickly realize that you can’t just build something like this yourself. Especially for the fingerprint, you need not only the scanner but also a control unit. This is installed in the door in a standalone system. Also the transformer and the motor. The cable routing must be secure as well. Therefore, invest the €1,000 directly in the door.

There is another alternative:
The prerequisite is also a door with a mechanical lock (about €650 extra). You then install the fingerprint separately, e.g., at the doorbell. There are systems like Gira, 2N, Doorbird, Busch Jäger, etc. The advantage here is that you can possibly replace the fingerprint without major effort. The disadvantage is that you have to find a place to install the control unit. This is also visible in your ekey diagram. We will have a KNX system, and I will put everything in the control cabinet there. Otherwise, you have to discuss with the electrician where to best install it.
Another advantage is that you don’t have to do it right away. It is enough to buy a door with a mechanical lock. Later you can install your fingerprint and connect it to the door. Flexible, but a bit more effort.

My recommendation:
If you haven’t understood most of it or want something simple, have ekey installed directly in the door and you will be happy. Otherwise, individual solutions.

But first talk to your general contractor. As I said, it will work 100% and don’t let anyone tell you otherwise!
