I installed this mechanical key code maybe 14 years ago. No issues. These can be bought online for as little as $29 on a sale. No battery. No wireless. No bs. Just buttons and open.

This style mechanical push button door opener has been on the market since 1970. What I see with many of the more advanced door openers is increased complexity, cost and potentials for failure and invasion of privacy. Oftentimes simplicity is the best approach. At least in my life that’s been the case.
With old and common designs, methods to decode are very well known, especially on cheap models.
The fact that it was enough for you means nobody even really tried to break in. The only thing it says about that lock is that it may have worked as a deterrent for some very unskilled thieves.

I'd never use one to secure a house as it's just not secure, the only place I do use one it to lock my back garden door. It's a decent deterrent, but a terrible lock.
 
I would never buy a smart lock. Moment the cloud service is discontinued now you are locked out of your home.
 
Palm veins network is better than finger recognition for closed subset of registered users (ie discriminating within a limited set, not in the open) if you can make them lay their hand on the reader and stay put for a couple seconds. Typical use case is for prisons.
 
What makes it a terrible lock?
Because the code on these particular mechanical locks are not safe. Let's say my code is 4567X, I could enter them in all these combos. As long as I enter any of these, it unlocks just fine. They are not secure whatsoever. My old work place had this lock and I could enter any combo I wanted as long as it had the correct numbers, my back garden lock is the same.

Depends on the brand, I use a Yale smart lock, but it does not require the internet and doesn't need a subscription. As long as I have the RFID tag, or even use my phone or watch to unlock with Bluetooth it works fine, if Yale goes out of business it will still work, all I would lose it the ability to control it over the internet.
