Simple Remote/App Controlled Night Lock for Disabled Users

Hi. I need to find and install (or let someone more knowledgeable do the work) a remote or app controlled night lock. The whole smart system thing is a bit too much for me and also costs a lot. The lock would only be used to lock the house for the night and to open it in the morning by someone who has working fingers but not their whole hands. Whatever, because now it doesn't lock at all.

And an unrelated question. Is there a smart system that can be operated with the eyes? Or any extensions for people who don't have functioning hands at all?

Greetings.

The easiest, quickest and probably cheapest .... drive to an existing lock. Installation basically without interference with the existing door and can always be opened from the outside with a traditional key.

This works more or less like this: https://youtu.be/G5_03uPCaCA

Eqiva Bluetooth lock drive probably the cheapest.... used for just over 100zł.

Come on!
