Less smart electric front door key turning lock?

Hello interwebz!

I am looking for a non-invasive front door key turning lock addon like https://nuki.io without too much brain. I'd rather run the brain myself in a way I can trust.

 The invasive version that requires changing the lock is easy to find. The non-invasive one, not so much...

Any hints?

Flemish software developer or free software user? Marianne Thyssen = BAD pick

Please take the following into consideration when voting for your EU member of parliament:

One of the few members of the EU parliament active PRO software patents, so AGAINST your interests was Marianne Thyssen (CD&V).

At the time, Bart Staes (Groen!), Dirk Sterckx(OpenVLD), Sp.a and NVA díd do a good job. Merde, even Vlaams Belang (friends know how hard this is for me to acknowledge) has supported Flemish SMEs on this issue.
