ᐅ Retrofitting a fingerprint electronic keypad lock!

Of course, years ago we didn’t think about it or didn’t consider it important to be able to open our front door electronically.

By now, our daughter is 6 years old and will start school this year. She also often plays outside with her friends. We want to give her a key, but we have to expect that she might lose it 😉

However, ideally I would like to upgrade to a fingerprint or keypad lock.

There are cables only at the doorbell, and I would like to avoid running new wiring; this probably isn’t possible with a wooden door anyway.

During my search, I found the Burg Wächter Secure Entry.

It has pretty much everything we need, but before spending 300–400€ I’d rather ask if anyone has alternatives, experiences with it, or recommendations.

Thanks

I do not want to make a personal statement. However, I recommend reading the article that can be found using the terms "CCC" and "fingerprint biometrics ultimately just a security placebo."

That’s not true. It depends on the type of fingerprint scanning used, such as live detection and so on… Any standard locking system performs worse. You really need to invest more for better results.

Since there is no electronic door opener, it will have to be a retrofit solution that replaces the lock cylinder with a "smart" one. However, you need to make sure that the battery inside doesn’t run out, or else your child will be locked out.

I would advise against using numeric codes and recommend using a fingerprint or token instead. With a numeric code, the child might accidentally reveal it, or someone could watch you enter it. Without evaluating the products themselves, Nuki is mentioned quite often.

Nuki can also be combined with Ekey, as there is a module available for that.

That’s why the numeric keypad is designed so both methods can be used.
My friend has problems with fingerprint recognition; often it doesn’t register. I would suggest registering multiple fingers.

@guckuck2 Thanks for the tip, I will check it out right away. The token solution is offered by Burgwächter.
I am familiar with the battery issue from work—there, access gates secure chemical storage, and they alert us in time before the battery runs out. We have two entrances, so we can always get in.

Somehow, I feel that tokens are probably the most secure option, especially in case of loss.
